1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad
.
6. The motherboard could be defective & needs to be replaced.

Try another hard drive in the system, sounds like the drive is going bad, then after replacing the hard drive, then go ahead and recover the system. Bad sectors on a hard drive can make it where it won't restore.

If you can get your hands on a windows boot disk, then you can try to format the hard drive, wiping it out and installing it can fix that problem as well.

FS050UA , COMPAQ PRESARIO NOTEBOOK PC CQ50-210US the screen has lines and a black spot


Hi,
Turn on the notebook and press F10 to get into BIOS screen. Even if the lines and the black spot appears then the issue is with the internal hardware of the notebook.
To check further connect an external monitor to the notebook and press Fn and F4 keys on the keyboard to get the display on external monitor. If the external monitor display is fine then the issue is with the LCD screen or else the issue is with the Video card of the notebook.

My compaq cq50 screen goes to black for no reason


Does it come back if you move the mouse or hit the keyboard?

If so it could be set in a couple of places.

Right click on your desktop , go to Personalize > Screen saver and verify your settings there.

It may also be in power options , go to start > control panel > hardware and sound > power options . Select change when the computer sleeps and adjust the settings there.
