Re: Problem starting notebook
Looking through the exhaust grill doesn't let you see well enough inside
to determine if dust is your problem. If the CPU wasn't spinning, the
laptop would immediately shutdown as the BIOS would detect zero RPM and
halt the system. That it takes 10 seconds could mean either dust has
accumulated which prevents cooling of the CPU or even the heatsink & fan
fell off the CPU. The CPU heats up and exceeds the shutoff threshold
configured in the BIOS. Whether the fan isn't spinning or the CPU is
heating up too high are protection measure to protect the CPU from
burning up (and consequently the surrounding components and
If the task of opening the netbook is too daunting to you, take it to a
shop. Ask them to open the case and blow it out clean. Ask them to
make a visual check. Make sure they check the fan will spin on power
up, that the fan is attached to the heatsink, and the heatsink is
attached to the CPU.
By the way, did you ever charge the netbook's batteries and retest?
It's also possible that your batteries are unusable. You could see if
plugging in the AC power adapter gets the netbook working (with the
batteries in and then retest with them out). You never mentioned HOW
your netbook is getting power. Could be something as simple as old
batteries that are dead and won't take a charge.
