Acer aspire 5100 notebook kb and mouse doen't work on boot up

try to boot in safe mode. press F8 several times before bootup, then select safe mode. better yet safemode with networking. and did you try hooking external kb and mouse thru usb? if it proceeds, try checking online for chipset drivers and touchpad drivers at http://support.acer.com/us/en/drivers_download.aspx

Check booting the system with safe mode and clean the drives.

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)

inside xp you can go to the hardware section and uninstall the usb drivers. when you reboot the drivers refresh for the usb and you can continue as usual.

Hi there
You can get all the drivers for that model from acer support site>>>>

Good luck and thanks for using Fixya!

try removing the battery and restart only using the mains lead. it worked on my aspire 5600

i had the same problem. apart from keyboard and mousepad, all usb weren't working at all... except the pcmcia slot. so i bought a pcmcia usb card and plugged in the usb mouse and keyboard in those slots. it works! at least on my aspire 5100

first thing you want to try and find out if this is a hardware or software problem. Try connecting an external keyboard and mouse (USB if you don't have mouse and keyboard ports)...then go into the device manager (On XP its control panel, system, hardware tab, device manager)...and see if your laptop keyboard and mouse is registered there. If so then uninstall them and reboot...there is a slight chance that they will reinstall and work, but may be more complicated than this. If they do not show in the device manager, then there is most likely a hardware failure and they may need to be replaced or check the connection.

kINDLY CONNECT A USB KEYBOARD AND/OR MOUSE TO TROUBLESHOOT THE NOTE BOOK IF USB KEYBOARD/ MOUSE (EXTERNAL NORMAL USB DESKTOP KEYBOARD MOUSE). THEN WE WILL BE ABLE TO TROUBLE SHOOT
