    Acer Aspire 3100, boots to XP but cannot work the cursor from touch pad or from USB mouse. Cannot gain control of the laptop. Not my device just helping a friend. A shop updated their anti-virus protection but did not register it properly. I registered it and got everything working. The owner used it that night all fine. Then plugged in a new USB cable (one with the flashy blue led's in it) to connect a printer. this caused the freeze up. Since then its been cold booted a number of times always the same outcome. I cant get to the Bios proper, only options on acer are which gives windows boot order not bios setup. keyboard and pointers don't work in screen either. Looks like a bios/motherboard issue.

Acer aspire x1700 black screen, makes high pitched noise, doesn't respond

You may have damaged or dislodge a component.
I suggest you remove the cover and reseat the RAM modules and all the cards in the expansion slot (unscrew them pull them out of the expansion slots and insert them back then secure them with the screws.
If it still does not boot up then you need to take the computer to a computer repair shop.

I have an acer aspire and my document cannot be edited because the back space and delete button are not responding.

If they are still unresponsive after a reboot it is possible that the keyboard keys have gone bad.

Bad news, The keys themselves cannot be replaced, the entire keyboard must be replaced.

No so bad news. You can get a replacement keyboard for an Acer for about $15-$30 (plus install cost). Any local shop should be able to replace it in about 10 it 15 minutes.

If you are ambitious you can replace the keyboard yourself. Find and order it online, then just google "replace acer aspire keyboard". There are a number of sites with instructions on how to replace it.

For right now: You can hook an external usb keyboard to the laptop and it should work without problems, until you can get the laptop keyboard fixed.

Unresponsive keyboard + mouse pad

I guess you have a mechanical problem, sounds like the mother board have some issues on starting all devices.

If you could use keyboard to go in the bios, and see the screen, if would be the OS that need to be repaired.

Keyboard/touchpad problem.

The keyboard and touch-pad are connected to an internal USB interface, If no USB interfaces are working at all this suggests that the USB host controller (a physical computer chip) has failed.
You can try a chip-set reset; disconnect both power and battery and hold down the power button for 30 seconds (timed), this will reset all chip settings to default and discharge any static buildup but this is in no way guaranteed to fix the problem. If the laptop is still under warranty arrange for repair.
In the mean time most of the Aspire 5100 series have a PC card slot on the side so you could use a USB or PS2 host card to connect a keyboard and mouse.
