My compaq 610 wont start up. went i connect de charger the powerbutton lights goes on en off.


When the power button blinks do you hear the laptop fans run on full speed? If that happens its because your laptop is overheating and is trying to cool down. It will not turn on until it cools down to protect from damage due to heat.

Use your laptop on a hard surface and dont block its vents with anything. If you want to use it on bed keep it on a laptop cooler or a thick book to allow ventilation.

If laptop doesnt turn on at all, the motherboard might be damaged. Take it to repair shop and check whats wrong.

I WAS HAVING PROBLEMS WITH OVER HEATING, NOW MY LAPTOP HAS CUT OUT AND WONT RE-START. WHEN YOU PRESS THE POWER BUTTON IT LIGHTS UP AND YOU CAN HEAR THE FAN OR SOMETHING BUT THE SCREEN STAYS BLANK. ALSO...


When a laptop overheats the CPU will shutdown, this is known as thermal overload. The laptop will not boot up until the CPU has cooled down. If this problem in not fixed then the CPU will eventually fail.
This problem is usually caused by a faulty fan or the fan and heat sink is clogged with dust.
Replace the fan if it does not spin freely and or remove the dust clogging the fan and heat sink.

My compaq laptop F500 has black screen when power on


That sounds like a power supply problem. That would be the first thing I would check. If it was the processor, you would have heard a long beeping sound or if it was the memory you would hear about three 'annoying beeps'. The main reason you indicated there is no display on the screen and that the fan spins for a few seconds then shuts off, would hint that power is not going to the mother board long enough to spin the processor or cooling fan. Hope this helps :)

Hp 6720s lap top running - vista does not load


If the laptop runs extremely hot, then CPU will shut down (thermal overload) and will not boot up again until it has cooled down.
Overheating problems is caused by faulty fan (stop spinning) or the fan and heatsink assembly is clogged with dust. Check the fan, it should spin freely and remove and vacuum the dust from the fan and heatsink.
Replace the fan if it is faulty.
