First clean the fans out - these get clogged pretty easily.
If it gets stuck where you cant turn it off - hold down the power button for 5 seconds.

Hopefully the system hasnt been overheating for so long it has damaged the CPU or motherboard.

If the fans are clean and it still does it, you may have a bad stick of ram or the mainboard you bought may have problems.
I would inform the company you got the mainboard installed that it is having problems right away in case you dont have much time left in warranty.

Good luck!

Can a Toshiba p15-s409 be upgraded to another motherboard and processor?

Motherboard is usually a big no when it comes to laptops as that motherboard was specific to that laptop. That is the way they are made. It will support a max 2GB of RAM, according to the specs.

The CPU? Well it depends on if, and that is a big if, the motherboard will support a faster P4 proc. I believe the fastest P4 that was made was 3.8Ghz, but have never found one. Then will the motherboard support a proc that fast? You have to look at the heat/cooling issue also.

If you don't want to get a new lappy, and don't have 2GB of RAM in it, then get more RAM. A 2.8Ghz with 2GB of RAM will run Win 7 fairly well.

No Power Issues on Laptops

There are 3 things to consider in order for you to determine a No Power Issue

1. Battery
2. Mother Board
3. AC Adapter

1. Remove the battery from the laptop

2. Disconnect all non essential cables (external hard drive, usb memory key, printer...etc.)just connect the AC Adapter

3. Take out the Battery....Usually there is a battery indicator that you can push at the back of the battery

4. By Now the battery power indicator should be full since it was never taken out

5. If still theres no light on the battery.... replace battery

6. Turn the laptop on without the battery

7. If the computer still did not turned on check the AC Adapter if there is light coming out

8. If there's no light that comes out from the AC Adapter. Reseat the cable from the AC Adapter to the Cord

9. Check if there is no light that comes out from the AC Adapter. AC adapter needs to be replaced

10. Otherwise the Mother Board needs replacing

If you have used the discs to try and restore your laptop, it will have formatted and destroyed all data.

I just purchased a toshiba mini notebook NB 505 it has about 5 hrs. of time on it. Went to turn it on the other night and when it starts up the screen was lite up but nothing else. I can not shut down...

It happens when the NB was not properly shutdown, NB was turned off due to battery drained and left idle or worst there is a problem with the mother board. You may try this; Turn OFF the laptop, remove the power sources (ac adapter and battery). Without power sources, hold power button 10 secs. Put back the power sources, and power ON the NB. If the laptop will not boot by doing this, take it back from the reseller for replacement.

I have a toshiba LT a205; the LED flashes 6x; what does that mean? the psu is rated at 19vdc, and puts out 18.5 vdc. The end of the power connector that goes to the mb only has 0.5 vdc on it, so I'm...

19volts is a nominal value. The AC Adapter will be fine from 18 volts up to 20volts because the power unit on the motherboard regulates the voltages very accurately.
You say you only have 0,5volts on the Mother Board power input. There's your fault. Between the Mother Board socket and the AC Adapter.
Replace the AC Adapter or Laptop Connection lead if you mean there is 0.5volts actually on the Mother Board but full oiutput from the Adapter.

Toshiba Satellite L300 shuts down when ac power plugged in

How about this step, try to turn off the laptop itself. Remove the cables and battery just like what you did before, then press and hold the power button for 10 seconds. Then, reinsert the cables and battery on the laptop and then turn on the computer itself. If the laptop restarts, shuts down or freezes with the AC power cables, two things that you should seriously consider. It might be the power cable itself, AC cable port or the circuitry going to the motherboard. And since you have cleaned out the fan and heat sink, you have isolated that problem. Have you plug-in another power cable on your laptop? If yes, then check if it works. Otherwise, the main issue is that the AC port is loose or the circuitry of AC adapter going to the motherboard is not not working. You can re-open the unit and check the circuitry from the AC port going to the motherboard. You may check the circuitry from AC port to the power supply if it is ok. If symptom persist, please contact your local dealer...

I do have a toshiba Satellite L300D and No full power or no display . the power only turn on but no booting . I am just wondering what could be the problem. In fact this happened only after I tried to fix...

As per your descritption, it might be due to AC adapter problem which is not giving enough power to notebook to power on. However, try to power on the notebook only on battery power or alternate AC adapter. If it does not turn on, then it might be due to motherboard problem due to some short circuit in the AC adapter.

Additionally, please perform the below steps before trying the above procedure:

1. Shut the computer down.
2. Disconnect the AC adapter and remove the battery.
3. Press the power button down for about 30-60 seconds.
4. Reconnect the AC adapter and the battery.
5. Restart the computer.

Are you sure the ac adapter is providing power to the system? You should check it with a multimeter first before ruling out a problem with the system.
