Toshiba Laptop Memory Replacement

When looking at upgrade options for a Toshiba laptop, you will find that upgrading the laptop memory is likely to have the greatest impact on the overall performance. Programs store their data in RAM when they are running. If multiple programs are open at once and the laptop runs out of free memory, it must begin using the hard drive to store and retrieve the extra data. Since hard drives are much slower than RAM, this results in slower performance. Upgrading memory allows users to run more programs with fewer slowdowns and speed up operating system load time.

Replacing your Toshiba laptop memory is one of the simplest upgrades to make. The basic steps are as follows:

  1. Disconnect the AC adapter and remove the battery to ensure no power is going to the laptop. This reduces any risk of electric shock when disassembling the machine. The battery is most often removed by sliding the battery slider and removing the battery.
  2. Locate the memory access panel on the bottom of the machine. It is usually marked with an icon that resembles a memory stick. In some cases it may be located behind the battery. If you have trouble locating this panel, consult your manual or a service manual for the exact location.
  3. Remove any screws securing the memory access panel in place and remove it.
  4. Gently release the two fingers holding the memory stick on each side and it should swing upwards. Carefully pull it out of the slot. Repeat for the second stick if there is one.
  5. Place the new memory stick in the lower slot and snap it down into place. Repeat for the upper memory stick if there is one.
  6. Replace the memory access panel and screws.
  7. Replace the battery and reconnect the AC adapter. Boot up the computer and test that the full amount of memory is recognized by the computer.

At this point, if the memory is recognized and the laptop is working properly, you are finished. If you are having trouble you may want to check that you selected the proper memory module for your machine, or the possibility that the memory is not seated completely in the slot.

Issues with third-party batteries and Sony laptops

Sony laptops are arguably some of the best Windows laptops available, but there are a few issues that many users won’t appreciate. One of these issues is a type of protection that Sony includes to prevent users from using third-party batteries with their Sony laptop.

Sony would prefer that users use only Sony laptop batteries, partly because it means they must be purchased directly from the manufacturer, but also to ensure quality. Users who have found a trusted third-party manufacturer for their laptop batteries, however, are likely to be frustrated by this limitation. Fortunately, there is a workaround to let you use third-party batteries with your Sony laptop, as the battery check is a software program rather than something included in the Sony system board. Follow these steps to disable the software check.

  1. Power down the laptop, remove the battery, connect the AC adapter, and power the laptop back up.
  2. Click the Start button and type “msconfig.exe”. You may need to enter your password to continue.
  3. Click the “Startup” tab and look for a listing for “ISBMgr.exe”. Uncheck the box.
  4. Click “OK” to save the changes, and choose to restart the laptop. There may be a popup once you restart; alerting you that certain programs have been disabled. Simply dismiss this dialog box.

Now you can install your third-party battery, and you should find that it works without problems. Visit our Sony laptop parts page to view other parts and upgrades that are compatible with your laptop.

Diagnosing a Laptop AC Adapter Problem

Laptop AC adapters can sometimes take a lot of abuse. As an external part of a laptop, they are designed to be rugged, but problems can still crop up from time to time. If you suspect that yours may be having an issue, here are some steps for diagnosing a laptop AC adapter problem.

  1. Try another power outlet. This may sound silly, but if you are not getting power to your laptop through the AC adapter, try another power socket to ensure that is not the cause of the problem.
  2. If possible, try another AC adapter. This may be more difficult, but if you have a friend or a repair shop that has a compatible AC adapter, try one that is known to be working. If the problems still persist, you know the AC adapter is not to blame.
  3. Try running the laptop without the battery. Sometimes problems with the battery can cause symptoms unrelated to the AC adapter. If the laptop runs fine when running only from the AC adapter, it is likely caused by a faulty battery or some other component.
  4. Look for signs of wear and tear on the AC adapter. Large cracks on the “brick” or transformer could be signs of problems, as can frayed wires or bulging. If any of these conditions look serious, replace your AC adapter.
  5. Listen for strange noises. AC adapters that are failing often make whining noises or other strange sounds. Replace the AC adapter if necessary.

If you have tried the steps above and are still uncertain whether your laptop AC adapter is faulty, it may still be a good idea to order a replacement. As one of the least expensive parts of a laptop to replace, it may be worth the peace of mind knowing that your AC adapter is working correctly.

How AC Adapters Work

Laptops are useless without AC adapters. They are what run your laptop when your battery dies. They are what charge that battery when you want to use it on the go. With that in mind, it’s important to have a basic understanding of how they do what they do, especially if it comes time to replace them.

A laptop AC adapter will consist of essentially three main parts: the cord that carries unusable AC to the box, the box that converts the AC to DC, and the cord that carries the usable DC to the laptop. Your house is powered with AC, or alternating current, because it travels well without losing energy, but alternating current is not usable by laptops. They require direct current, or DC, power.

The box of your adapter technically does more than simply converting current, or rather there is more to the process. As alternating current enters the box from the cord connected to your wall, it is run through a transformer. This drops the current from about 110 volts to around 19 volts, which is what most Sony laptops can work with. Other brands of laptop often use 15 Volts, but most other variations are plus or minus a volt in either direction. The current then runs through a rectifier which essentially forces the current out in one direction only, thus making direct current. Finally, the current runs through a regulator, ensuring a steady stream of voltage despite any changes in power consumption. After running through all these components, the current continues through the second cord, and into your laptop.

Knowing the basics of AC adapters will allow you to make some more educated decisions on replacement or upgrade adapters. First, check your cords. Match your main power, or AC, cord to whatever plug you’ll be using. For example, plugs in Europe are different than in the US, and plugs in your car or on a plane are different than the ones in your home. Also, invest in a surge protector to help ensure the longevity of your AC adapter, essentially protecting it from being overloaded.

Your laptop will also require specific voltage from your adapter, and a minimum wattage as well, typically listed on the underside of your machine, or available from the manufacturer. When it comes to wattage, you can get higher than what is listed on your machine’s specifications, but going lower can cause the box to overheat, and shortening the life of the laptop AC adapter.

As for the DC cord, the main thing to look for is the connector. If it doesn’t fit the DC jack on your machine, it won’t do you any good at all. If you’re not sure, check with your spare parts retailer, chances are they will be able to assist you in finding an adapter that will fit your machine. Also, when looking at replacing an adapter, be sure to confirm that the problem isn’t with the physical DC jack on your machine, as it can become loose or unsoldered. A loose DC jack can cause problems that may simulate issues with your AC adapter and may require the DC jack to be repaired.

Review of types on connectors found on AC adapters

When it comes to laptop AC adapters, there are a wide variety of connectors that connect the adapter to the laptop’s power supply. Manufacturers specifically try to make their adapter unique for each model, and even compared to other manufacturers, to avoid a user plugging an adapter into the wrong machine, which could cause damage. Here we will look at a few of the most common types of connectors.

Barrel Connectors

Most modern laptop AC adapters use a “barrel” type of connector. It consists of a cylindrical shaft that is hollow inside. When the barrel is connected, a pin (tip) goes inside the barrel, and the outer portion of the barrel makes contact with a different part of the power supply. The tip usually carries the positive pole while the barrel carries the negative pole. Barrel connectors come in a wide variety of sizes to avoid confusion between different manufacturers and models. For example, HP laptop parts often use a different pin and barrel size than another manufacturer such as Acer.

3-Pin and 4-Pin Connectors

Some laptops and AC adapters use a 3-pin or 4-pin type of connector, also referred to as a “Snap and Lock” type. These connectors use a large cylindrical connector with 3 or 4 pins inside. Snap and lock connectors are particularly useful in laptops that are designed for durability, as they are very stable and secure, and not prone to breakage.

Oval Connectors

Oval connectors are similar to barrel connectors, but utilize and oval shape to prevent connecting them to standard barrel connections, since connecting an adapter to the wrong laptop could cause damage to the system board or other components, requiring a costly laptop repair. They are not used frequently.

Octagon Connectors

Octagon connectors are similar to snap and lock connectors, but they utilize 8 pins that give even more stability and a more solid connection.

Finding the proper HP Laptop AC Adapter

If your HP laptop is not charging the battery while your AC adapter is plugged into the laptop, you probably need a replacement Laptop AC Adapter. It is important to ensure you have the correct AC adapter for your specific HP laptop, as using an incorrect adapter could potentially cause damage. Here are a few methods for finding the proper HP laptop AC adapter.

The simplest method is to use an online parts locator tool. Many online retailers offer such a tool. Simply enter your HP laptop’s model number into the search and the tool will provide you with the proper replacement parts that are compatible with your specific model. The benefit of this method is that you are often given a choice of both OEM and third-party Laptop AC adapters for your HP notebook. Third-party adapters are often much less expensive than their OEM counterparts, and as long as they are purchased from a reliable source, should perform every bit as well as the OEM version.

Another method of finding the correct AC adapter for your HP laptop is to use the support software provided. Click Start, the Help & Support. Here you will find the product name, model number, and serial number. This will help you locate the correct part for your HP laptop. The product’s serial number is usually located on the bottom of the machine as well. You can call HP support directly to order a replacement AC adapter, though this will usually be the most expensive route. Another option is to call or email an online retailer with your model number and serial number, and they can often help you locate the correct part.

Finding replacement parts for an HP laptop is not as difficult as it once was, with the benefit of online parts locator tools. It is now a simple process to find parts even for older models. Take advantage of the many tools available for finding an AC adapter for your HP laptop.

Buying and Installing a Dell Laptop Battery

Buying and installing a Dell laptop battery replacement can be very simple, and doesn’t have to cost a lot of money. There are a few things to consider, however, when buying a replacement battery.

Buying a replacement battery directly from Dell is one way to ensure quality, but buying directly from the manufacturer is usually the most expensive option. Instead, many buyers may want to consider a third-party retailer. Make sure you find a reputable retailer who stands behind their product, especially one that offers a satisfaction guarantee and a solid return policy. If you buy from a third-party retailer with a reputation for quality and customer satisfaction, you can pay less for your replacement laptop battery and still have the peace of mind that your battery will work reliably.

The best way to ensure you purchase the correct replacement notebook battery is to use an online parts locator tool. This tool allows you to choose your laptop’s model number and then shows you the parts that are compatible with your model. It is a good idea to compare the voltage and amperage from your old battery to ensure they match the new battery you are planning to buy. In some cases, you may have the option to buy a battery with more capacity and longer battery life than the one you are replacing. Most of these batteries accomplish this by including more cells. For example, the original battery may have 6 cells, while the replacement battery has 9 cells, and therefore, longer battery life.

Replacing the battery in your Dell laptop is very easy. First, shut down the laptop and disconnect the AC adapter to ensure that no power is running to the machine. Second, release the latch near the current battery, and remove the battery. Align the new battery in the same way the old battery was removed, and snap it into place. You may need to fully charge the battery before running the laptop from battery power only.

Benefits of Memory Upgrades for Netbooks

Netbooks are becoming increasingly popular of late, due to their incredibly portable size and convenience. However, as a result of their size, many netbooks don’t have the kind of powerhouse hardware you’d expect to find in a laptop or desktop machine. One way to offset this and cheaply improve the performance of your machine is simply to upgrade your RAM.

RAM, or random access memory, is the storage your computer has for data that can be accessed immediately without searching or pulling it from the hard disk. You can think of it like your hard drive being the books in a library, and RAM is how many you can check out and reference at a time. The more RAM you have, the more easily accessible data your computer can pull from, which reduces the amount of time it spends polling the entire hard drive for your machine.

There are different types of RAM, each one progressing and becoming more and more efficient and effective. When purchasing your RAM, you’ll need to check it against your computer’s specifications. The newest form is DDR3, which means it allows data transfer rates of 3 times the original form. Some newer netbooks like the Toshiba NB305 support the higher speed DDR3 RAM, which makes it an attractive machine for users seeking a little more power.

When looking into purchasing RAM, you’ll want to check your machine’s configuration to see how it’s set up. Some are set up in banks, which is built for pairs of RAM. Others allow them to be placed individually. Your computer will handle any size listed in its specifications, but make sure that if they are in sets, that all sticks in that bank are the same size.

As far as pricing goes, you can get 2 GB sticks of memory for around $55 to $60 at many memory suppliers. Most Netbooks like the HP Mini 5100 have 1GB memory standard, and can be upgraded to a maximum of 2GB due to mainboard chipset limitations. Generally speaking, and upgrade to 2GB will do plenty to improve the speed and performance of any netbook, making it an even more useful and convenient machine.

PCMCIA Cards, Cardbus and ExpressCards – What exactly is the difference?

PCMCIA, Cardbus and ExpressCards are similar technologies that are very easy to confuse with one another. In fact, many experienced computer users still get the standards confused. Let us try to shed some light on the differences between these three standards, and eliminate some of the confusion.

PCMCIA

PCMCIA stands for Personal Computer Memory Card International Association, the organization which standardized the format. It is an interface for connecting external memory cards, modems, and other devices to a laptop as a means of expansion. It later began to be referred to as “PC Card” instead of its long acronym.

The first cards were Type I cards, which had a 16-bit interface and were 3.3 mm thick. These Type I cards were prevalent on many of the early Compaq laptop systemboards. Type II cards are somewhat thicker, at 5.5 mm, and use either a 16-bit or 32-bit interface. Common Type II devices are modems and network cards, which often have to use a dongle, as their height does not support a full-size jack. Type III cards and devices are even thicker, at 10.5 mm thick, and can support full-size connectors without dongles and even hard disk drive cards. Type II Cards were the standard size of PCMCIA Card for some time before they were replaced by CardBus.

CardBus

CardBus is the successor to PCMCIA. In fact, it is the name used for cards and devices that supported the PCMCIA 5.0 or later specification. It has much in common with the PCI bus on a desktop computer, as it provides a 32-bit, 33 MHz PCI bus with a smaller form factor designed for laptops and notebooks. Most CardBus slots support earlier PCMCIA devices, but CardBus devices can not be inserted into older slots, as they are notched differently. If these newer cards are forced into the older PCMCIA slots, it can cause damage to the card slots and a relatively expensive laptop repair.

ExpressCard

ExpressCard is the latest successor to be developed by the PCMCIA organization. It was introduced in 2003 to replace earlier form factors. There are two form factors included in the specification that are used on laptop systemboards; Expresscard/34, which is 34 mm wide, and ExpressCard/54, which is 54 mm wide. ExpressCard/54 cards can be rectangular or L-shaped, supporting either 26 pins or 68 pins. ExpressCard/54 slots are often used on HP laptop systemboards to support a remote that conveniently hides away in the slot. The ExpressCard interface allows for much more bandwidth than previous technologies, up to 2Gbit/s. This allows users to connect high-speed disk drives and other devices that need more bandwidth to operate effectively.

Understanding the progression of these three technologies will hopefully clarify their differences and applications. Currently, ExpressCard slots offer the best performance for external devices, but it will likely be replaced by a faster technology in the future as well.

Ways to Extend the Life of Your Laptop Computer

Laptops can sometimes be troublesome devices, and anyone who has had either a hardware or software problem with a laptop may have wondered if there was anything they could have done to prevent it. While some problems are unavoidable, there are a few steps that any user can take to help prolong the life of a computer and prevent problems from occurring.

  1. Cleaning

Dust and dirt are two of the biggest enemies of a laptop computer. Since dust buildup can sometimes cause overheating, it is important to ensure that it doesn’t affect the function of laptop fans or block air circulation. Turn off the laptop, remove the battery, and gently spray compressed air into any vents in the laptop to dislodge any dust buildup every few months.

  1. Repairs

If you suspect you may be in need of a laptop repair, don’t put it off. In many cases, you may be able to perform the repair yourself. Do a search for Toshiba laptop parts or HP laptop parts, for example, and you may find the replacement parts you need to solve the problem yourself. Putting off a necessary repair could cause more damage to your laptop and lead to more problems down the road.

  1. System Maintenance

Not all laptop problems stem from hardware issues. In many cases, users purchase a laptop because their old one has become very slow. This is often caused by software problems. Every few months, uninstall any unnecessary software on your machine, defragment the hard drive, empty the recycle bin, and clean up temporary files. If the system still seems slow, you could consider backing up necessary files, formatting the hard drive, and reinstalling the operating system.

  1. Upgrades

As a laptop computer ages, it may not have the performance to handle newer software. This can be a good time to make upgrades to your machine. For most laptops, upgrading the memory to the maximum amount supported is the most cost-effective upgrade. Upgrading the hard drive is also a great way to gain more storage space for files.

At some point every laptop becomes obsolete and will need to be replaced, but if you follow these steps, it will be less likely to be due to hardware or software failure of some kind. With a little extra care, you may find your laptop outlives its expected life.
