Try reseating the RAM and any pci card plugged in underneath. If those don't help - it's probably a crack in the board or a soldered joint broken. Very hard to fix in many cases.

1) Removed graphics card? Sounds like this is an NEC desktop computer, not laptop. 2) Loud pop? Have a look at this Vai,

http://capacitorlab.com/visible-failures/index.htm

See if one exploded.

(Those are Radial Aluminum Electrolytic Capacitors. They do pop. What REALLY makes a loud bang, is if a Solid Polymer Capacitor pops! Explode like a small grenade inside your computer case!

May not even see it anymore. Just a place on the motherboard where it was, and shrapnel from it all over inside the computer case.
When THEY pop, you KNOW it! )

My toshiba satellite U505 turns off suddenly when i turn it on. What might be the problem


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:

Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

It does sound like a complete motherboard failure, do you have a recovery disc for the laptop? remove the hard drive and leave it out, remove one stick of ram, remove the main battery, and remove the wireless card. Now fire up the computer to see if the acer logo comes up and then it should go to blank screen with the cursor blinking, if it works to this point, turn off computer. Now install the hard drive and load the recovery disc, make sure the boot sequence is set to start the dvd driver first, if everything works and you have full control we are starting to get somewhere, if it fails, this is where I would change the hard drive and see if that makes the difference, if it does, replace the ram and wireless card back into position, and last the main battery. If all this fails it leaves the motherboard as the problem. one thing I forgot to mention swap out the ram if windows freezes.

Toshiba Tecra M2 Series


Was the laptop on when it turned off? It may be a PSU problem but we can determine this by removing the battery. Make sure you disconnect the AC adapter while your removing the battery. Inspect the contacts and make sure`there are no black marks or any other dirt. Leave the battery out and plug in your AC adapter. Try the power again. 
There are a couple of possibilities in terms of problems that I can suspect so far. Did anything out of the ordinary happen when the computer just stopped working all of the sudden.
1. Battery has failed and short circuited the contacts 2. Power supply failure 3. Motherboard could have failed in style. 4. Power contacts for the AC adapter are damaged.
