1. Faulty RAM - try to remove, clean, re-align.

2. Remove battery, press power button for at least 30 secs. w/o AC power. Attach to AC power without

battery. power on. Hard reset

3. Faulty Processor - very risky of dismantling and aligning processor.

4. MOBO problem.

My compaq presario cq60 laptop screen goes blank intermittantly. I can not get the screen to come back on without forcing a shutdown.


Get some canned air and blow out all the dust you can.
Get a laptop cooler to take heat away from the bottom of the laptop.
Take it to a repair shop

Compaq presario cq40-144tu system starts with the start up sound of processor..but then screen goes blank and just the caps lock, num look indicator blinking.....


Could be ram or GPU. Find some one you know with a laptop that has working ram that is similar to yours. On the bottom you should be able to unscrew a panel that will expose the ram sticks. Remove yours and replace it with the known working one and turn the system on. I know that usually you're supposed to hear beeps if the ram is bad but I've fixed several systems where there were no beeps, just no video so it's always good to check. If the same problem happens plug your VGA on your laptop to a monitor or TV and see if there is no video. At that point it would more then likely be the GPU needs to be re-flowed. It could be other things but if it sound like it's posting and you hear everything running (hard drive ETC) but there is no video then 80% of the time it's related to the GPU which is a BGA chip. Similar to when people get the 3 red rings on an Xbox 360.

Without more information i would have to say that your inverter has died. The inverter provides light for your screen.
