Aspire 5520 has LCD Display. The
screen displays becomes dark/ dim if there is no backlight. There
are two parts responsible for lighting the display. First is the CCFL
(Cold Cathode Florecent Lamp), which is the back light and the second
is the Inverter board, which provides high voltage to the CCFL. These parts are inside the LCD screen. Either
of the parts may be faulty or in some rare cases both. Also, the video data cable may be loose or faulty, which can be identified only after opening the top cover. So,
my advice is that you get it properly checked by any professional for
replacement of Inverter or CCFL.
Hope it helps! Good Luck! Thanks for using Fixya! CreativeTECH
To check whether the LCD screen itself if the issue or the backlight or inverter. You have to carefully look in the screen and see if you see anything on it. It would be extremely dim but try white background and black screen. If you see something in it, then most probably it's either the backlight or the inverter. For that you need to buy those from the market and install it, OR IF YOU ARE NOT A TECH GENIUS I WOULD RECOMMEND YOU TAKE IT TO A DEALER IF ITS IN WARRANTY TAKE IT TO ACER THEY SHOULD FIX IT FOR FREE.(I dont know the rules of Acer, but most companies fix that for free)
As by your description, the FN F7 key combo did not solve the problem. Please restart the machine , press F8 then select from the list "Safe mode" then press enter. Then see how the Touch pad reacts in Safe mode. If it works perfectly in safe mode, we can assume you have a software problem that is preventing it from working in normal windows mode.
Please download and install the latest BIOS for your machine. The E525 has a issue where the TP just stops working, upgrading the BIOS solves the issue on the E525... Acer Aspire 5920 3813 BIOS
Please install one of these drivers for the desired Operating system...
Acer aspire has inbuilt web camera and therefore will work only if the correct drivers are installed. Please uninstall the drivers first from control/panel/add remove programs. Next reboot the system and then go ahead with the installation.
This is often a problem with the backlight on the LCD panel. If you gently tap the side of the LCD does it flicker more? If it does, then there is a loose connection in the LCD panel, and you might be able to get a comptuer shop to fix it, but it usually is expensive. If you don't mind using the laptop as a desktop, then get an LCD monitor and a USB keyboard and mouse, and you can use it as a desktop.
want to again see/want to see again the icon of your web cam? go to control panel and there you find the Scanners and Cameras..or other ways will you install new software ..hopefully it helped you...>(email@example.com)Tag__ City
