Battery on Toshiba E740 doesn't run the unit. As soon as I disconnect the external power, it goes dead and nothing is saved

Remove your battery plug in your a/c power - you should get a power led light on your unit - if not power led try your power pack on someone elses toshiba or try there power pack on yours - if a good power pack starts your unit then refitted the battery whilst its running and left it charge - that means you have a dead power supply - if it doesn't respond with and alternative power pack your d/c input cct has failed. new m/board.

Will it start if attached to a charging cradle directly?

it has nothing to do with the ram, it is the issue of the adapter or battery for toshiba laptop, if the output volatge form the adapter is not steady, the light will get yellow and blink,try it on another toshiba laptop. if it is normal, u should test the toshiba laptop battery by the multimeter, connect the electroprobes wiht the anode and cathode, if the pointer does not fixed in a short time ,the battery is the issue. change it for a new one.

Are you using a headphone or the Pda's speaker?

The speaker could be damaged or disconnected - try connecting a headphone to the Pda to see if the sound works.

Hi, I noticed that the firmware that you have is not the latest, the last provided was 1.0623.049 which was released a few years ago. I would install this, in addition to the other patches from the Toshiba web site. Hopefully this will overwrite any software quirks for you. regards, Keith

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.

I get much the same, but it comes and goes. For a week or two it will behave itself, then goes pop for a month or three! Do you find if you have external power (cradle or USB) that it will switch off? I also find that if I switch it off from battery power, it will switch itself back on, but then the power switch is ineffective for 6 or 7 seconds. Then you can switch it off, only to repeat the whole excercise again (and again, and again, and again...)
