I've replaced the CPU in my laptop from a Pentium dc 6100 2Ghz to an i5 560m 2c4t 2.6GHz CPU, which is listed as compatible with my motherboard in the service manual. This cpu did work "fine" with the laptop for a month or so.
However the laptop kept shutting down at when it reached 75c in games. This isn't that hot at all for a laptop, so I assumed some bios protection had been reset when I changed CPU. I am sure the laptop had previously gone over that temperature before with the old dc chip without shutting down.
So I tried to go into the bios to have a look. However, my laptop now turns itself off, as if the power cable was pulled off, about 2 seconds after turning it on. No beeping. Sometimes I just about get a flash of POST before it turns itself off, Weirdly, it works without the fan plugged in but I am only brave/stupid enough to let it run for six seconds or so without the fan plugged in...
I've tried switching over to the old cpu, disconnecting everything from the motherboard, using the VGA port... no success. I've got a new fan on the way in case something broke when I replaced (and cleaned it) when swapping CPUs. Any other idea what it could be?
It's a HP Dv3-4100sa. It's pretty old so more a 'project' than a useful laptop now, although with an SSD, 8GB of DDR3 and that i5 it will be good enough for most things still
