T43 Interrupts; Hardware Interrupts High CPU Usage (PICS)

#1 Post by powertone » Sun Nov 15, 2009 9:44 am

I have this problem, having high cpu usage for my Interrupts; Hardware Interrupts which I knew by using process explorer, task manager doesn't show it. Usually cpu usage hovering around 70-90% because of this Hardware Interrupts. I'm using my notebook as usual (Firefox usually, sometimes I just let it stay IDLE to eliminate any of my installed softwares that cause the problem but its still there) and BAMM, high cpu usage for Hardware Interrupts! And sometimes my svchost.exe for network service got high too or when I adds up all my svchost.exe cpu usage (Its 8 btw). Using firefox v3.5.5 for browsing. Been using this notebook almost 5 years if my memory serves me right and only now its being like this.

OS: Windows XP Professional (Using retail Win XP Pro) Is it OK to disable hidden partition in BIOS?
Keyboard: Salvaged my sister dead T40 keyboard to my T43 (Is it maybe the culprit?)
HDD: Still the original HDD Fujitsu MHT2080AH 80GB
Touchpad: Left button is dead.
Bluetooth: Already installed the driver but in control panel the icon is broken as in the same big X red box.

Other abnormalities:
Can't shutdown my T43 even after fresh install, always restarting even after patch sp2 and sp3.

My process explorer screencap without hardware interrupts problem.

Another problem, theres no uninstallation option for my intel wifi wireless driver.

This is the 8 svchost.exe that is running

Interrupt ; Hardware Interrupt using 70% at min.

edit: sorry for the earlier pics.

all this screencap is after I uninstalled all of my T43 drivers and softwares. Now my T43 only have WinXP Pro SP3 OS and my installed softwares without any official IBM drivers but the hardware interrupt problem still there.

I'm from Malaysia, Kuala Lumpur.
Full spec:
IBM Thinkpad T43, 2668-CA1,
Window XP Pro Retail (Lost T43 recovery disc) & install SP3; no hidden partition.
1GB of DDR2 RAM,
Fujitsu MHT2080AH 80GB HDD,
Fingerprint reader (Never use it)
ATI X300,
14" 1400x1050.

Once my CPU fan stop spinning, took it out and sprayed it using maybe WD40 (I'm not sure the exact brand, forgot). Let it dry and voila, it spins again with the same annoying noise only old T43 fan can make.

Any input is welcome. Thanks.

Am I the only one having this problem? No one experienced this?
