Toshiba E740 Power Problem

Hold the power button down until the unit shuts off, wait 10 seconds then turn it on again.

Upon restarting, make sure to choose Start Normally if the startup failure menu comes up.

sometimes these will go into an automatic sleep mode and will restart once you power it down and restart..

Either a power supply fault or there is a fault in the main circuit board. You may find a replacement power unit (they are held in by two clips ) at an electronics recycler or auction site like e-bay, but the main board is not an available part.

Hello,
I have looked around for you and here's what i found:
Try holding down the power button on the front of the unit till you hear a beep (4-5 seconds). If you don't the unit will power on, but won't reset the video settings. Most people don't hold the button down long enough.
i hope i have helped and i hope it works,let me know how goes !!

check the following power supply components
power transistor of the supply
zener diodes
rectifier diodes

In my opinion it is always very risky to buy some second hand unit because you can not be sure if every hardware component works properly. The best solution for you is to contact service partner and let them check the PDA. It is also possible that power supply electronic has some malfunction

In y opinion there must be some problem with battery power supply. In my opinion you should contact service partner. I hope that your unit has still valid warranty.
