Acer 5100 laptop - keyboard and touchpad dead...

In my wisdom....I pulled my USB stick out yesterday without safely removing first. This caused a light blue screen with horizontal lines to come up, and now both keyboard and touchpad refuse to work...apart from that the laptop boots up fine.

Is it possible something has short circuited? If not, any ideas on what it might be?

its a driver failure for both devices.

Unfortunately its a tricky problem... the most proven solution to this would be to repair the OS installation
#2
As in a complete fresh install?

I'm happy to do that - but my boot sequence is set to hard drive first, this can't be changed as I can't press F2 to enter setup on boot, and so can't boot from CD...

How would I go about a clean install?...Or repairing the install?
#3
Oh I should also add that I have a USB mouse which refuses to work- possibly more than a driver failure?

If something as basic as a keyboard fails, it means you've either got a hardware or a software problem, and the easiest way to figure out which it is is to rule out the software. To that end, what you need to do is try using the keyboard without Windows being loaded. This should be easy enough. You know when you start your laptop up, you get the Acer screen which perhaps tells you to push the F10 key to enter Setup, or maybe tells you other keys to push to enter or do other things? Hit them repeatedly. If they work outside of Windows, you know the hardware is good, and that it's just a Windows fault. If not, it's time to be calling the warranty line.

Btw, safely removing a USB device means nothing in terms of physical safety. All it does is makes Windows write to the device anything not yet written, which saves you from losing data on a pen drive, and stops filesystem damage to the device. USB's designed to be hot swappable, so you should be able to plug and unplug devices all day long to your heart's content. But only if you're reaaaaaaaaly bored.

Ah ok, well yer...can't press F2 on boot...or anything else for that matter.

And it's out of warranty :-(

Now - this may be asking to much....any idea what it costs to repair? Is it a motherboard replacement? And if so - is it worth just replacing the laptop?
#6
maybe its not F2 key.. if you cannot access bios setup at all, than the problem may be more severe i.e. hardware like the dxx says

if you can access bios and change boot sequence dont perform clean install UNLESS youre prepatred to loose ALL your data and softwares

heres how to repair install: http://www.microsoft.com/windowsxp/using/helpandsupport/learnmore/tips/doug92.mspx
#7
Well I can't enter the BIOS in the normal way...pressing F2, ESC or DEL....also pressing F8 to try and boot in safe mode is irresponsive.
#8
Thanks for the help, but is the general conclusion that its hardware?
#9
dont give up just yet :)
apparently different makes have different method of accessing bios setup.

for ACER its CTRL + ALT + DEL Have a look at here:

I'll give it a go, but normally I can press F2 to enter BIOS, and F8 to boot in safe mode, now I can't do either...
#11
oh OK.... well ive got some ideas but theyre based on try n error which would take a lot of your time...
better go to pro or get a new lappy

sorry couldnt be of much help
#12
My guess is the keyboards wired to the USB circuitry and you shorted it when you pulled the device. Easiest way to test if the keyboards completely dead is to keep tapping the caps lock key when you switch it on. No light, no keyboard.
#13
I'm happy to try out your ideas - I just can't right now as I'm not with the laptop, if you can post them here I will try later and report back.

Pretty sure caps lock light doesn't show either...

If the keyboard is dead - is it worth repairing, or is it a new lappy?

You have lost drivers for internal usb hub. Many laptops will run mouse and keyboard through this. You need a standard mouse or keyboard (not USB for obvious reasons). Look in Device Manager. Easier with mouse, lots of Tab'ing and arrow keys with keyboard. Delete Mouse and keyboard and then any USB stuff (drivers will be there, just not working). Now, before doing anything else do a restart (using start, shutdown etc and NOT by pushing reset button). Once restarted they should re-discover. If not, do new hardware search. Hope that explains ok.

You assume it has PS/2 ports.
#16
But I'm pretty sure my laptop hasn't got a PS2 port for a non usb mouse...
#17
bump :-) anyway I can try removing the devices in device manager without the use of mouse/keyboard obviously....

And a USB mouse won't work...

And I don't have a PS2 port...
#18
So options.

1: Pay through the nose to get it fixed.
2: Say sod it and buy a new one.

3: Buy a PC Card USB adapter and plug a mouse/keyboard into that. Think yours has a PCMCIA slot?
