It seems to be an overheating problem, but not entirely sure of that. The problem occurs during any intense disk access, eg... virusscan, defrag, etc... I managed to get a full scandisk to complete, by sticking the pc in the fridge while it ran, lol. I checked this site and found there is settlement claim pending by Toshiba: http://www.a70m30xsettlement.com/ <snippet> Plaintiffs in this class action, known as Elihu, et al. v. Toshiba America Information Systems, Inc., claim that Toshiba Satellite® A70, A75, M30X and M35X notebook computers contain a system defect that causes them to freeze, reboot and/or crash, shut down, and/or lock-up with a black screen due to static electricity. Toshiba denies these claims and denies that it did anything wrong. Moreover, Toshiba asserts that it proactively addressed Plaintiffs’ claims by developing and voluntarily providing an effective remedy. </snippet> This is the part I am most interested in: "Toshiba asserts that it proactively addressed Plaintiffs’ claims by developing and voluntarily providing an effective remedy." I cant seem to find out what the effective remedy is, would appreciate any help, thanks... |

verheating. So if it is out of warranty you can either fix it yourself or have somone else do it for you. If you want to do it yourself, locate a factory service manual so you know how to open up the case in such a way that it can also be put back together again. Next, look for the obvious. Is the heatsink gummed up with dust? If so clean thourougly with pressurized air can. If it seems clean, then watch the cpu fan as you boot up and stress the computer. If it does not spin up, or runs very slowly, then replace the fan. If this seems ok, watch the gpu fan if it has one in the same way or the case exhaust fan if it has one. If all fans are spinning up nicely then pull the heatsink and really clean it. Next, clean the cpu die of old compound and then put 1 drop of Arctic silver or other high quality compound in dead center of your cpu die. A drop the size of a grain of rice is correct. Then replace heatsink making sure you redo wahtever restraining scheme the chipset uses. The pressure of the heatsink will spread the Silver correctly. If the laptop is still overheating after this then you may have a crack in mainboard that only shows up when the temp rises in which case taps for that board. All these steps are very doable once you get over fear of cracking open the case.Good luck |
