    Hey Guys,

    Upgraded my laptop to a T9400 (Engineering Sample).

    It runs fine when plugged in, encoding video etc.... The issue is when the laptop is running from the battery, it'll just bluescreen within about 5 mins of unplugging it... every time without fail. I have the latest BIOS 1.13 installed.

    I'm guessing it's because it's an engineering sample? Would formatting the PC be worth a shot? I'm using Windows 7 Ultimate at the moment.

    Any advice appreciated cheers.

    What CPU did you have before, the T9400 needs a higher voltage, maybe there isnt enough when on battery and it blue screens, I do undervolting with RMClock and if I select a too low voltage it will blue screen, I maybe wrong, think its something to do with the voltage (VID) though.

    Had a P7350 before.

    Thanks for the tip I figured it was something along those lines, just played around with my power settings on Win 7 and changed the "Minimum CPU Usage" from 5% to 100% and it's working fine now although battery won't last as long.

    Just have to watch your temps now, the P7350 is 25W, where as the T9400 is 35W, I changed my CPU form a P8600 to a x9100 but the x9100 was 45W, I noticed a big increase in my temps when gaming but no real diifference in performance so I put the original back in, I have the 8930 which is abit of a pain for running hot, this may not be the case with yours but just something to keep an eye on.

    When you upgrade the CPU be sure to watch your power adapter supply.

    There's your problem, Kashinoda.
    Engineering Samples are not meant production chips, and as a result can have unfortunate quirks and instabilities such as yours.
    Had you spent the extra cash and gotten a production T9400, it would be a safe bet that you wouldn't be having that problem.

    Intel SLGEB & SLGEA are great options of your looking for T9800/T9900 spec CPU's and very affordable if you look on ebay.

    Ive found they are very stable if you get the final version and the same core stepping

    Yes I'm well aware, but like I said a fix was found I'm happy to life with slightly sacrificed battery life. Also the core on this is 2.66ghz (sometimes 2.7) which is actually the T9550? Swings and roundabouts, not bad for £65!


    No heat sensors on the engineering sample!! Well if they are windows reckons it's at 250oC haha, the 6935G's cooling is pretty good... also this laptop ships with P9600 also so I'm assuming it can cope with the T9400.

    Don't follow your logic, the P9600 puts out less heat then a T9400.

    Well I am running X9100 ES and this one is stable and runs as cool as dog's nose. I was ripping a Blu-ray which took me 10 hrs but temps at the end reached just 55° C. Works fine on battery as well with battery life being 2Hrs 20Min approx.

    What I suggest, is have a look in Windows power management and go to advanced settings. Look under CPU and play with the values to see if that works for you.
