Hi, I have an acer aspire 7730 that was working properly, both the key board and mouse suddenly stopped working. I fixed a usb key board and mouse that worked for some time and also stopped working. Now the laptop powers up and gives an option in which I need to use a keyboard before it will boot to windows. no usb port now works. Any help will be appreciated Eno

Hi,
I hope i can help resolve your problem for you.
this may be a problem relating to your system device driver files.
Try This:-
go to My Computer/Control Panel/System/Hardware/Device Manager. at the bottom of the page you will see USB.
If you have any yellow symbols ( exclamation Marks ) then the driver has been corrupted, or installed incorrectly.
if you have a system restore disk. this may solve the problem for you. or recovery cd.
If you require further assistance, please ask.

Try booting your computer from CD ROM with the OS CD/DVD already inserted and when prompted just try repair. If that does not work re-install the same on the same 'partition' assuming it to be C by deleting the the windows system files only. While doing so keep the internet on and immediately after the basic version of the OS is installed and the m/c boots-up for the first time, go to the official website and download the latest drivers for every component like toch-pad, keypad, display, audio, etc.(i.e. almost all the drivers)

Almost same problem: the mouse froze.
Found a nice solution at another website: switch off the pc, unplug the power supply cable AND remove battery. Press "on" switch for 20 seconds. Now re-install battery, plug back power supply cable, and switch on. Worked for me (what exactly worked for me I don't know but hey)
Good luck.

it might not be a problem with the software.
With the power out I would try taking the keyboard out and reseating the keyboard into its slot.
Turn on the laptop and press F2 to see if you can go into the BIOS. If you can then you know your keyboard is working. If you can't get into the BIOS then you know the keyboard is defective and will have to be replaced.
If you can get into the BIOS also make sure to get out and let the laptop reboot, if you cant do the ctrl alt del to get to the login screen then you know its a Operating system problem cause it works for the BIOS but not for the OS.
Hope this helps cause now you know how to tell if its either software or hardware related.
