CTRL-Lock Problem

By darren ·
Hi there,

Firstly thank you in advance for any advice forthcoming.

Client has a Acer Aspire 3515 running vista 32 bit service pack 1.

From the start up IE bios screen the keyboard doesn't seem to work. F2 wont let you into the bios. Once the PC actually loads into windows nothing seems to work but on closer inspection it seems that the CTRL is locked. As the keyboard reacts as if the CTRL is pressed.

I have subsequently found that if i press CTRL-ALT-DELETE and then click Cancel and return to the desktop i can type normally. But on restarting the keyboard goes back the the CTRL LOCK.

I have checked Sticky keys and they are not running. I have removed sticky keys from the Registry. Still happened. Brought sticky keys back from the registry back up so i can use them again should i want.

I have inserted a usb keyboard shows the same symptoms.

I have uninstalled the keyboard and reinstalled the keyboard drivers from the acer website.

I have updated the bios to the latest version.

I have Googled high and low and cant seem to get an answer to this problem.

Help me before i take a sledge hammer to my customers computer please..... Arrrghhhh!

I am at a complete loss.

Darren

Have you...

Tried a live CD to see if it is the Windows installation or a hardware issue?

Well then start off with the easy steps

by OH Smeg In reply to Live CD

Do a Repair Install of the OS.

If that doesn't work reinstall the OS from scratch after wiping the HDD.

The customer has done something to Windows and messed things up. If you don't know what that is it's faster to reinstall.

Of course I do have 1 client who parked a 40 Ton Excavator Track on a computer once because it Pi$$ed him off. So I know that cures all problems as well.

Start Easy

Have you removed the keyboard from the laptop and reinstalled it. Physically, I mean. Sometimes this seems to help this particular problem.

Don't need to do this as the Live CD worked

by OH Smeg In reply to Start easy

So it has to be something to do with their Installed OS.

Start attacking the OS now to fix this.

Dumb solution that might work

by paige_l In reply to CTRL-Lock Problem

I was having this same problem with my supervisor's computer. I found that by pressing the ctrl keys simultaneously, then doing the same with the shift and alt keys, it turned itself off and the problem hasn't repeated itself yet. Obviously it looks like this solution is a bit late for your problem, but maybe if other people are experiencing this, my answer might help.
