Acer Aspire 5820T Pc Notebook - Its not detecting the usb drivers. No usb ports work and neither does the Web Cam. Showing as Unknown Device under the usb devices.


I would guess the drivers are either not installed, or the wrong ones are installed. Go to the Acer website and select your model and download the current drivers from there and install.

I have ACER ASPIRE 2920, the power suplly can't turn ON


There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

If this did not work, try also disassembling the laptop & make sure that all main components are seated properly. Also make sure that all ribbon cables interconnecting the various components of the laptop are tightly connected.

Problems whit my acer aspire 2920 display


Check your memory card. Reseat or clean its edge connector with soft eraser.Do this after you shut it down properly , battery disconnected, and no any other power source is connected.

That is the first thing to suspect. Or try it also with a spare good ram card.

ACER ASPIRE LAPTOP 2920 NO DISPLAY


Ckeck if your adaptor has power on the connector to laptop.

Might be damaged power cord (to and from the adaptor) or broken adaptor.

While there was power in the battery, it was running, but not charging.
Now the battery is emty and can't be charged because of broken adaptor/cables.
If you find there is no power from the adaptor, bepair it or buy a new one.

Do not try to repair the adaptor by yourself if you are not a technician, it is DANGEROUS !
Either give it to a qualified servicer, or betteer, buy a new one.

Regards.
