Sometimes my laptop keyboard will simply stop functioning or have extreme lag. But it's different than the lag we are accustomed too. It's more of a one key takes about 10 minutes to appear and even if i continually press key's, it would not show all the keys pressed, only the first or maybe second one.
There appears to be no apparent pattern to this. It happens with or without battery power attached. It happens in the middle of anything. So, I really am doubtful it's connected to a specific issue or something.
I'm on an Acer TravelMate 2420, about 2 weeks old.
It is probably some system process that automatically starts up in the background like windows indexing, automatic updates, or system restore function kicking in to do its task for a few minutes or so and then shutting back off. These processes are a BIG system drain and can make computers slow down or even freeze temperarily. Since having these running automatically is NOT a needed process I would suggest turning off "windows indexing and system restore" and change "automatic updates" to manual.
I don't really think that's possible. Since it's more of a random occurance thing? I can't do all my work for the night in safe mode to see if it pops up If there's no other way I can do that, but I'd rather want to avoid it if possible?
I suggest going to security here because it might be malware though I still feel it to be a conflict, enable all start ups in msconfig simply most malware will be removed if you follow the steps in the link given here; however, in the rare case that the malware beats the steps mentioned, then the link goes on to tell what to do after that.
The prefetch, is the system's way of having those things needed to start a program ready on standby. I only suggested the prefetch deletion because it may have ophaned entries of uninstalled programs which sometimes cause a problem.
I did everything you said, and it still happens off and on. I think your initial diagnosis is correct though. I discovered that when they keyboard stops working, sometimes I can click the mouse pad buttons and get a few keys out. I discovered this with my frustration and hitting things when I couldn't say brb
Anyways, I thought 'hey lets look at task manager'. So just 2 minutes ago I had the keyboard malfunction occur again and I got to task manager, I noticed CPU usage at 100%! It was stuck at 100% too, because I know sometimes it spikes. So I took a look at what was hogging it. I found a task called LSASS.EXE taking up 70%
I don't know if this part is relevant, but when I was trying to get out and shutting down the PC it shifted the 70 to System Idle. I'm not sure what that is, but I lost track of the LSASS task.
- meaning all three links, or everything in the first one link, because this sounds like malware
- have you checked with links 2 and 3, what did security say then
- have you thought about reinstalling with your restore disk(back up your data first)
