Laptop computers are subject to a lot of wear and tear, especially on their moveable parts. The monitor is one of the most used and abused parts of your computer as a result of this, and also its sheer size. Fortunately, it isn’t that hard to find and replace an HP LCD monitor for your laptop.
The first thing you’ll want to do is identify your machine, with a model number if possible. Typically, this will be displayed on the underside of the laptop on a white sticker called the service tag. If you’re not sure what is what on this sticker, write it all down. The model number identifies your machine, and the product number narrows it down even more.
If you are unable to find your specific model number, you may need to remove the LCD itself and find a part number on it. To do so, look at the front of your monitor. It will either have screws or caps along the edge facing you as if you were using the machine. If it has caps these can be removed simply by popping them off with a tool. Remove the screws beneath around the perimeter of the screen. Then, take a corner of the bezel (the part of your computer case surrounding the monitor itself) and carefully remove the entire face and set aside. Now at the bottom of your laptop, you should see screws on the hinges which will also need to be removed, carefully. Once this is done you should be able to lower the monitor itself face down to the keyboard, revealing its backside, which will list its specific part number.
If you do attempt to do this at home, be sure to remove the AC adapter and the battery. Remember always, safety first. If you are not comfortable with doing this, take your machine to a local repair shop, or contact your manufacturer for further assistance.
When shopping for replacement LCDs, there are a number of specifications of which to be cognizant. First and foremost will be size. Especially when purchasing a new laptop monitor, you will be locked into a specific size, so make sure your new monitor will fit your machine properly. Aspect ratio refers to the height and width of display, for example a 16:9 would be considered a widescreen display format. Resolution is typically the gold standard of performance rating. The higher the resolution, the more pixels the monitor will display. More pixels allow for a sharper, crisper image. Most common displays run at WXGA or XGA, depending on the aspect ratio. There are many other specifications that come in to play that you may wish to discuss with a computer repair shop or retailer, but those listed above will be the most influential to the quality and function of your display.
