20 Most Recent Toshiba Portege M400 PPM40U01000E Tablet PC Questions & Answers

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.

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

have you had any power surges lately?
Try taking the battery out of the laptop and starting just on power.
if this doesnt help then take battery and power and leave laptop for few hours then try again on only power or battery.

Let us know how it goes.

i did find this manual for it
maybe it might be somewhere in it of how the bios sees the hard drive. normally a bios will boot to the DVD drive first then a hard drive so make sure you dont have anything connected like a USB or a cd in the DVD drive unless it is the OS software. also disconnect the network cable if it is plugged in.

Go to the Toshiba Mobile support web site for you exact model. Select Drivers download. Select Windows 7 32bits or 64 bit and download the latest versions of all that relate to the Tablet module, and that includes the Wacom driver.

If you Windows is genuine you can uninstall all the Wacom drivers then execute the Check new hardware wizard ( of Hardware changes) or even Windows Update
