Freezes whenever AC plugged in
The problem is, the notebook (toshiba satellite A300 1t2 model to be precise) freezes or restarts on ac power plug in but works fine on battery. It charges though when power is connected on shutdown/ when its powered on "may freeze when on or remains on for a little while before freezing or restarts). A very frustrating experience that has no end/limit. Any meaningful solution is greatly and urgently needed. It works fine in safemode whether ac is plugged in or not.
I did lots of checks and fixes i read.Like, disable processor, install standard vga drivers instead of the real drivers to see if its a display related issue and other fixes i read on other forums. Pls help if you have a better fix that works/ worked for you.

Try this work around, until we can find a permanent fix. In SafeMode Go to control panel--> device manager---> go to processor----> disable one of the two processors --> reboot normally. Or you could try to disable your processor there. see if that will make a difference.
I've installed applications to check the heat and its always within low limits 55 to 60 degrees celcius. I've installed speedfan, battery care and other applications to manage system resources. i think there may have been a problem with power handling in normal mode or some unknown device conflict.
BMS,
The reason why I am seriously inquiring about the temperatures is a bit odd. I really just wanted to see if it is similar to other Toshiba's, that have had the same problem in the past. Toshiba's of the M series have had trouble with a NEC/TOKIN OE128 Proadlizer Capacitor. It is a SMD capacitor and therefore difficult to fix for the DIY'er. The habitual behaviour was that the temperature would go up whenever the AC adapter was plugged in, causing the capacitor to fail. It should be located by the CPU, close vicinity anyways.

I can confirm tht the problem is the nec tokin oe907 capacitor.
there is a guide how to replace the bad capacitor
Bliss Matha, wondering if you could assist me with something to figure this out. Is there any chance you could download any of the programs that are available to measure the temperature. Something like the speedfan utils and post your temp on battery power and when you plug the AC adapter in?
