HAVE you tried to remove the battery and than PLUG the AC in ? SEE if this helps and if that doesn't put the battery back in and take the AC out and TRY it again.
IF that doesn't WORK you may have your computer set on Hibernate or Sleep mode? THIS is in your control panel in the start menu under the POWER SETTINGS...... You should see the problem if you do get the computer running again and it happens again.

Also try to hold down the power button for 5 seconds or until it beeps and than push it again to reboot...

There are a number of things that could cause this.
Starting with the simple diagnosis and moving onto more difficult problems:

1.) Check the On / off button is not sticking. If it does not free up after pressing it, the laptop will shut off. cleaning the area with some meths or isopropyl alcohol will help free it (laptop unplugged)

2.) If there is a small cut off switch (located just below the screen where the lid hinges close, see that it is not sticking, this causes the aptop to shut down if the lid is closed.

3.) Next, check to see if it will work plugged into the mains, with the battery removed. If it will, then get the battery checked. Check also that if the battery is fitted, the latches are in the lock position

4.) Check the AC adaptor green led light is not pulsing or flicking, it should be steady green. if is IS flickering, try a universal one. If the problem persists, you may have an internal fault on the motherboard

5.) Check the security of the DC jack, if this is loose or sloppy or feels worn, you need to get the jack replaced (see below), leaving it in this condition can cause arcing and permanent damage to the motherboard

6.) Check the adapters output voltage using a voltmeter, with the red probe on the inner contact and the black probe on the outer contact.

7.) Try swapping out the ram (if accessible) sometimes a ram module goes bad and stops the laptop from switching on, at this stage, disconnect the hard drive and see if it switched on with it removed.

After that, you are almost certainly looking at a strip down of the laptop, depends on whether you feel comfortable doing this..otherwise a repair technician will be needed

Possible causes will be:

A. The DC jack cable from the port to the motherboard is damaged (check continuity with a multimeter set to Ohms)

B. The Power capacitors or diodes on the motherboard are damaged (probably new motherboard needed)

C: The laptop has overheated at some point and the graphics chip has unsoldered, CPU fan failed, or CPU dead.

A good technician will be able to diagnose the fault from a few tests

Hi,
Good day. You can try to do these steps which is usually a normal solution to this kind of issue:
1. Take out the battery of your laptop
2. Remove main supply, or power cord
3. Hold power button down for 30 secs,
4. Put only power supply in or power cord Note: do not put battery in yet
5. Turn laptop on
6. Put the battery in.
If this will not work you might consider contacting toshiba tech support for laptop for other resolution. Hope this information will be helpful in resolving your issue. Thanks for using fixya and have a great day.

You've to replace the ac adapter, if it's brick doesn't get warm or LED does not glow on Power Jack on the laptop. offcourse, check with the wall different sockets

power jack can also be loose. so jiggle the cable to find out.

if notebook is getting power, you can remove the battery, ac adapter, hold and keeep pressing poer button for a minute, then, turn it on.

finally, you can take out hdd and ram, put them back again and turn on the laptop. hope it will help
