Computer start-up my computer will not turn on. I have a presario C500. I got it about six months ago.

Computer is probably too old to recognize an SSD. You may be able to find a firmware upgrade. Did you boot into the BIOS and try and find the SSD?

Regular maintenance of your Compaq Presario laptop helps to keep the machine running properly.

Keeping the fans clean is especially important, because the fans blow out hot air and bring in fresh air to cool down the laptop.

Fans attract dust, however, which can slow them down, resulting in a hot laptop.

If the laptop overheats, vital parts can cease functioning altogether.

Consequently, keeping your laptop's fans clean is crucial.

or Remove an HP Presario C500 Fan Assembly to clean it

HP Presario C500 is a laptop that, like most other laptops, requires a clean, functioning fan in order to work properly.

If your fan is too full of dust to function properly or needs to be replaced because it is no longer working, then your computer could be in danger of overheating and crashing.

Instead of having to purchase a new laptop because your C500's fan has failed, remove it and clean the fan or replace it with a new one.

Turn off your computer and unplug all the cords and cables from it, even the power cable.

Turn the laptop over and remove the battery, then remove all the screws at the bottom of the computer with a Phillips-head screwdriver.

Remove the two face plates from the bottom of the computer and you'll see the hard drive and RAM below.

The face plates will come out easily once the screws are removed.

Remove the two screws holding the hard drive in place and then lift the hard drive out.

Remove the screw found directly below the hard drive.

Turn the laptop over again and pop off the keyboard.

If all the screws at the bottom of the computer where removed, then the keyboard will come right out.

Remove all the screws underneath the keyboard and case and then lift the case enough to access the fan assembly in your HP Presario C500.

Unhook the cable coming from the fan into the motherboard and remove the screws holding the fan in place, then pop the fan out of the computer.

Hope this helps

Look for it in the power options on your laptop.

try,,holding the delete key down as it is starting up,,,will the computer boot into Bios?
do you see any information on the screen when you start the computer at all?

Contact HP this is a serious fault and it should still be in warantee so they should fix it for free.

Hi All,


This happens because of static energy storing in the motherboard components.

We can try power drain to resolve this issue.


Try doing power drain by taking out the battery & keep holding down the power button for complete one minute to drain out the power from the computer components. Restart the computer after putting the battery in.
Try restarting the computer only with the AC power, without the battery & vice-versa.

That should resolve the issue, if the issue persists, then you have to contact service center.


Hope that information helped you!!
