keyboard not working(using onscreen keyboard)

2057 Views 5 Replies 4 Participants Last post by  PC person
My keyboard has stopped working. This happened once before. I took it to a shop, then they told me they couldn't find anything wrong. After I took it home, the keyboard was working again, so I wonder if this will be temporary too. My system has been overheating in the past few months. I can hear the fan running very fast then the computer will just plain shut off. It was after this happened a few days ago that when I turned it back on that the keyboard wasn't working

I have tried to reinstall the driver which device manage says is kbdclass.sys, I downloaded that file, but it won't install, nothing happens when I double click the icon.

Hi PC Person. Are you using a P2 or USB keyboard? Will you please post you computer specs? Also please download Core Temp and post the results.

You can see my specs under the my system tab. it's a ps2 keyboard, built into the laptop. I already have core temp, what exactly do you want me to report? The temp would be different depending on what I'm running, when I run eq2 or starcraft 2, or practically any program that demands a good amount f system resources, that's when my fan starts "screaming" and my computer is likely to shut down. Right now when I only have firefox, core temp and the onscreen keyboard running the fan is very quiet.
I take it that the PC is no longer under the Dell warranty?

You may need to open the access cover and thoroughly clean the cooling assembly.

Blow any dust/debris from the fans and vents.

Aldo check the keyboard connection to make sure properly seated.

The overheating may have damaged the motherboard.

you may want to consider a laptop cooling pad if seems to be overheating. if it is overheating, you really need to do something before you damage other components. You may need to clean the dust as previously suggested, you may also need to replace the cpu thermo paste.
Well, I took it somewhere and they did clean out it out. At least around the CPU (after a pretty hefty fee) I thought the problem was solved, but tonight after playing Starcraft 2 for a few hours it shut off again.

Yes, so I think I will invest in a cooling pad. Are they generic, pretty much any one for any laptop (so size is really the only consideration.)

But, I'm wondering how it got this way in the first place. What's making it overheat now, if not dust in it. It's gone almost 2 years never having done it, just normal wear and tear? I never had it happen with my desktop of 5 years 98-03. Or another system me and a friend built.
