My m400 wont start at all, just an orange light blinks at the power light

Use this service manual to solve the problem.

this should be what you need

Only a select few (very few) M400's have a 3G wireless module, and from what I understand they do not use a Sim Card as they use CDMA technology. You can tell if your unit has the 3G unit with several different ways.

A. Check the device Manager

B. Try and install the 3G power management driver, and see if it loads.

C. Check using Toshiba Utilities if installed

D. This is the hardest way, but the best. Remove the keyboard, and if the 3G unit is installed, it will be at the top right hand side of the case under plastic film. (I have had three M400's, including the top of the range one that I am writing this on, and I have never seen a 3G unit).

If you do have the 3G unit installed, look for an ESN number. You should then be able to then call Verizon and have the service activated.

You look very much the unlucky owner of a busted battery.

I'm afraid the battery will have to be replaced. Meanwhile, do not use it with the power supply; not only it will do no good, as you already determined, but it might damage the power supply itself.

This happened to me. The computer will not work with the battery in it.
Solution: Take battery out and plug in without battery... It should work,
You will need to get a new battery

hi dear i dont think you can any test on this my addvice is take to toshiba service center ...

thnx

I have the M400 and it also does this. I don't know much about computers, but I found out when you apply a little pressure to the left of the touchpad and beneath the keyboard as you're flipping on the power slider, it boots up much more often. I know... sounds crazy and stupid, but it works for mine and it's been doing it for almost a whole year now. It doesn't work everytime, but whenever the light flashes and the fan cranks up to a million RPM i just pull the battery out

Any hope you may have left other than an expensive repair, is to remove the battery and leave the unit in an airing cupboard for a week and pray. Then replace the battery and try again. No change - then nothing lost. I know it's basic, and best done as soon as the damage was done, but has worked for me in similar circumstances. Don't be tempted to use a warm oven.
