My PSP 3.40OE randomly keep turn off itself when I'm playing games,watch movie or transfer dataa to memory card.Then when I turn it on it's display Sony Entertaiment logo and prompt me to setting the date and time .It' happen again and again and I do nothing to my PSP setting or fw.Try to restore default but not succesful.

maybe it's something to do with your battery... try run with adaptor connected see whether the symptom re-occur or not? If confirm ur battery "kong", replace the batt. U can get the batt at rm 29 from lelong

I have try with adaptor connected but the symptom happen again...u mean which battery CMOS or rechargeable battery.

He means the rechargeable battery.

Try taking out your battery. Plug in the AC adapter and try starting up your PSP. See if the symptoms persist.

i guess some problems with your hardware. is it a new set or still under warranty? if yes, better exchange for a new set.

do you use cwcheat or put any plugins inside your seplugins folder in the memory stick? If you do have plugins, try to disable them all inside recovery mode...or better yet, backup your memory stick to your pc and then reformat the memory stick..my psp got that prob before, reformat ms then everything ok already..

or if you have warranty, just replace with a new set like david888's idea..

I try what's you say and my PSP won't turn on as usual...try few time, it's on then for few minutes turm off itself
