thanks for the advice
hai, i saw your posting and thank god it really helpful. i own a p1010 and some how it cant turn on twice!. what ever i do, and what ever tricks available in the internet i had tried it all, all with no success. so the first time around i had to sent it for repair and because my tab's warrant had already ended i had to fork out a lot just to make it running. the repair shop just stated that the battery and the touch screen need to be replace. how stupid of me to fall for that. after that my tab is usable again. then it happend again. two days later the same problem occurred. now i know it is not the hardware but the software that causeing all this headache.
now, with your posting, i opened my tab, disconnected the battery for 15 minutes and walla my tab is ok again. phew...save me a lot of money.
i see that the problem might be in the software. i see that alot of p1010 owners face the same problem here after upgrading from froyo to GB. and i notice that the blank screen syndrome would happen if we put it in a standby mode (my standby mode would be you touch the power button once just to make the screen goes blank).
just my 2cents.
