T40 keyboard problem

Hi,

I have a problem with my T40. Sometimes when i am writing, the keyboard and mouse becomes slow and inresponsive. (couple of times a day)...

In other words, it lacks and sometimes take up to 5-10 seconds to complete the sentence I am writing and I can not do anything until the sentence is complete...

Now here is the question: why does it do that, and is it the system, driver
or hardware? I can imagine something about the keyboard buffer being filled and waiting to be emptied before the new input can be processed?

Anybody have had this problem or any posible solutions to this problem
please e-mail me at rauff<SPAM>@daimi.au.dk (rauff ad daimi dot au dot dk) or secondly post here...

Best regards

Are you connected to a network when this happens? I have a somewhat similar problem at work, at first it bugged me but i have learned to live with it. After unplugging the ethernet cable the problem would go away.

I think people like to post here possible same case scenarios, suggestions, solutions to constantly build a data base for others to use for similar problems. That is why this is such a great place.

Ohh yeah sorry it was not ment that way, just because I dont check the forum that often... But it is a really nice forum for your problems

Yeah i am on WAN, so it might be that...

I think it's caused by IBM software "Keyboard customizer Utility", you can uninstall it and try again.

See if it happens while you have the wireless adapter turned on. Some are reporting high CPU usage with a weak wireless signal and the Atheros cards.

My brother had a simular problem on another computer, and it turned out to be a corrupt video driver.

Open task manager (ctrl + alt + del), and see if any processes (except the System Idle Process) are using a large amount of CPU cycles.

I've noticed, particularly on my T41, that sometimes Windows extremely modal, keyboard shortcuts and clicks are ignored for 30 seconds, then slowly get executed every 20 seconds for a few minutes. Happens without wifi active (a Cisco Aironet 350 pc card on that TP), docked and on AC, logged into a domain, software like Office, Visual Studio 2005 (i know, Beta and buggy), etc. running.

Sometimes I pound the keyboard (old IBM model M, it can take it), sometimes I just restart and take a Microsoft-enforced coffee break.

Hehe microsoft enforced coffeebreaks

I will try the uninstalling the keyboard customizer...

The problem is that when i am using my laptop for anything I am always on WAN...

Though with strong connection...

Can you modify your keyboard anyway so that one button is used as a windows button? And how?

(regarding WIN key mapping)

Yep, I see you figured out how in your other post. ,:)

Bingo ... I've found that Symantec Antivirus uses a HUUUUUGE amount of RAM (for what it does), and on some test systems I noted that it also would gobble up CPU cycles at spontaneous moments. Maybe uninstalling Symantec and using another virus/firewall product will help your problem. I've done so in a test environment and seen improvements.

I'm not sure about that ... I have it not installed on my work T41 and I have similar "lockup" problems anyway. YMMV.

Hi,

Well, in my case I can always reproduce such slowdowns after a network access IF the bluetooth adapter has not been opened since the last machine reboot.. so there are several things that can cause such behavior...

I have tried both Symantec and Norton, although I know its probably the same engine code...

But I most admit, I have now fully updated the system once again, and have not had problems in a while now...

Any other good Anti Virus to invest in?
