Compaq Presario 1700T overheats and shuts down


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

What will be the possible cause when my laptop compaq presario C700 is automatically turning off?


If the laptop shuts down and won't boot up until it has cooled down, then the CPU is overheating and goes into thermal shutdown. This is caused by either a faulty fan or the fan and heatsink assembly is clogged with dust.
If this is not fixed then eventually the CPU will fail completely.
Check the fan to see if it spins freely if not then replace the fan.
If the fan and heatsink is clogged with dust then remove the dust from the fan and heatsink fins.

Compaq presario m2000 imediately shuts down after


Check for blocked air passages - vacuum out the fan ports. (Don't use canned air - you'll just blow the dust inside, where it will act as an insulator and help things overheat.) Make sure the fans are actually turning. If there's any mold growing inside, that could cause the problem too.And for more contact http://tinyurl.com/m7ghqz

Compaq Presario M2000 - Fan not running


It appears your CPU is overheating and is shutting down.
Does the fan spin at all when the laptop is switched on?
The fan could be faulty, if it does not spin freely.
To test the fan, try removing it and connect it to a 12 volt DC power supply, if the fan spins fast then it is OK and the fault is on the laptop, possibly the power supply to the fan. In this case you need professional help.
If the fan appears OK then the problem could be insufficient too old heat sink compound between the CPU and the heatsink. You will need to remove the fan and heatsink and the old compound and put some fresh heatsink compound on the CPU/heatsink and reassemble the fan/heatsink.

Laptop Wont Boot Up


In that situation, try to boot it in SAFE MODE. You get into this by pressing F8 during boot up. The menu will come up and you choose the mode you want. While in safe mode you will have to try and use system restore to go back to when the computer was working. It's like PC time travel.

Presario 2200 CPU fan appears to be dodgy


Not really, since the fan is controlled ny a thermal sensor on the Motherboard. You may want to start by having the fan and heatsink assembly replaced.
