Start taking your laptop apart piece by piece and test it after each removed component:
1. Remove the hard drive and test the laptop.
2. Remove the DVD drive and test the laptop.
3. Remove the wireless card and test the laptop.
4. Unplug the display panel from the motherboard/video card and test the laptop.
Continue taking it apart until you have only three major components connected: motherboard (with video card), processor, and memory. If you still experience the same problem, most likely it's bad motherboard.
By the way, before you start, try reconnecting the memory module. If you have two modules installed, try removing them one by one and test the laptop with each one separately.

Hi, how's it going?
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.
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.

Ok, if you have a installation disc, insert it and boot from the disc. Once you get the option, try a start up repair.
If you cannot find a disc, try booting in "safe mode", once in windows, do a system recovery to the last known good settings.
Hope this can steer you in the right direction.

My Presario CQ50 won't turn on even when plugged
Most likely issue is that the cord has been damaged, or that the power jack has become loose.
First step is to remove the battery and try plugging in. If the light comes on, on the front of the laptop, your battery may be dirty or defective.
If the unit will still not power, you will need to test your cord or look into a new cord. If the cord puts out the proper 19v (give or take .5v) then the issue lies with the laptop jack. Otherwise a new cord will most likely do the trick.

I sometimes accidentally switch the keyboard to
There should be a sequence that you need to press to change it from one type of keyboard characters to another. Look for a key that has the symbol of a keyboard on it. Most likely this is the key that is causing you the problems. Typically you have to press the Function key that is near the space bar as well as the key with the symbol on it to change it from one character set to the other. Evey laptop keyboard is alittle different than the next when it comes to which keys are "functions keys", so you will have to examine your keyboard to find the correct key on you laptop.

The stop error code is most likely STOP:0x0000007B because windows XP doesn't have the correct SATA controller driver to install without assistance.
If available, try setting the SATA controller in BIOS to ATA or Legacy Mode.
If not available, then you will need to download the SATA controller Driver and slipstream the driver into the XP version you are trying to install
