D640 and Bios A10
Recently my laptop seemed slow and after checking the performance tab in task manager I found the CPU utilisation to be spiking at 35% every 2 seconds continuously. Hence the slow
performance. Note the slow down occours only if the network cable is unplugged...

Using TaskInfo2003 I discovered that the proces using my cpu is "DPC Time Place Holder" and I think it's something related to acpi power management.
My Bios is version A10.
Any problem with this bios version ?
Thanx

I think you are on the wrong forum site. Dell has never made a D640, They did make a C640 and they still make a D600 but no D640, or at least not yet.
As to your problem it sounds like the system has a virus or some type of hijack or a Trojan horse.
Do a google search for the program and see what it is related to.
A10 works fine on all the C640s I have but if you have a D640 I have no idea what version BIOS you should use.

options, the abnormal cpu usage stop. It's the nic driver that is bugged, and with the cable unplugged causes high cpu usage...

The reason I suggested a infection is because my C640 and i8200 do not do that when I am connect wirelessly and I have no cable connected to the NIC. To my knowledge I have never changed that setting you posted.
