Check to see if the ram is securely in place. (that will cause a pc to not boot, usually there is a beep code tho)

SOURCE: C500 Laptop won't come on power button just flashes

Have you tried attaching an external monitor when the LCD screen is disconnected from the motherboard? this connector is located under the keyboard strip – a piece of plastic just above the keyboard.
If it works, this way, then the video cable isn’t seated properly in the connector on the back of the screen. Plugging the video cable back in should fix the problem.
I don’t know how comfortable you are with taking apart laptops but I think that this information could be useful for you.

SOURCE: Compaq C500- Will not turn on

Power drain would be a better solution in this case.
1.first shut down the comp
2.unplug the charger
3. remove the battery
   and after press and hold the power button for 60 seconds without any charger and the battery.After the 60 seconds replug the battery and the charger and turn the computer .

Samsung 46" LED - Screen goes to black every 15 sec and then comes back shortly. Do I need to replace tcon or main or is there something else possibly wrong?


Hi Todd,
Screen goes black means back lights go off. The power supply may not be responsible for this problem. Please check back light on command from main board. Good luck.

I dropped my T4220 and now the screen is blank and its beeping. There are no visible cracks on the screen or the casing... The fan is on and nothing else :( Any help pls...


There could be anything from a wire off to a hair line crack on the mother board. If nothing much works apart from the fan, it is possible the mother board is now damaged.

My fujitsu t4220 will not power up


try a universal charger/power cord to see if that is the problem.
if not you can always return it.

only other option is the battery.
this has been the case with a laptop I used to have. turned out vista was the real problem though. (LOL... Crying...I HATE vista)

I get a blank screen and 4 beeps what's the problem?


Hi,
This could happen when the RAM contact is not proper, may be due to dust. Remove the memory modules from DIMM slot, clean it (no moisture please) and reinsert it. This could mostly solve your issue.
Please come back and rate my solution if it turns helpful for you or also if you need more clarifications. Thnx
