psp cant read battery well

[elite999]

my psp's shuts down on a 15%battery left and the time indicates that there is 1:10 hours left and sometimes it shutdowns at 18% is this a problem or not and what is the solution?i nearly tried everything and i used a different battery but the result was the same so it is a problem with the psp...need help

[rceckspurt13]

a firmware update may solve this problem.

[elite999]

i did that 3 times now and nothing happened

[rceckspurt13]

wells dont know what is wrong. Do you have any extra LEDs or anything?

try it on another psp to confirm its your psp. im pretty sure its your battery though. its probably gotten old and its loosing its charge memory. its about time to get a new battery. and when you do remember to drain the battery down untill you get the warning that the battery is low. then charge it. dont just keep on charging it thats what makes them not last long. good luck

[rceckspurt13]

that could be the problem...accept he said he tried a different battery  with the same result. i dont think its the batteries fault.

might be a problem with the power connector on the mobo. if thats not connecting as it should then that could cause the problem. but it really does sound like a battery problem.

no i am sure that it is not a battery problem...i went to an electronic fixer and ,, after examination,, he told me that there is a problem with the diode so do u think he is right ?? if not tell me what to do

[rceckspurt13]

you could try just letting your psp sit for a week or so with no battery and it may reset itself. Then at the end of the week put in a nice freshly charged battery and see if the problem persists. My camera had a similar problem.

correct me if im wrong but lithium batterys dont lose there charge time once its there time to go it does

[elite999]

nobody read my last post i said that i said that maybe the diodes are the problem

[elite999]

so nobody know a solution to this problem oh well

[rceckspurt13]

ell there is one really obvious solution......buy a new psp. Sorry I can't think of any way to fix it.

it's hard for us to resolve the problem as we can't see the psp. it's like asking a mechanic to find a problem with a car over the phone. Very hard. you have two options, 1) buy a new mobo or 2) buy a new psp.

[elite999]

i went to a mechanic and told me about the diodes that they are missed up so when the battery becomes at 20% they stop getting more did anybody read my post

[ApheX]

Unfortunatly i don't know how to repair that. hopefully some here will be able to explain how.

buy a new mobo

The only way to fix this kind of problem is to set two PSP side by side and take measurements on them both.

One as the reference and one as the problem that you are trying to fix.

If you have a mutlimeter and a logic probe you could trace it. Check at points on a system that works and compare to the system that doesnt.

You may find the signal is fine all the way into one of the major chips on the motherboard and there is nothing to do but replace the motherboad.

I am not saying to replace the motherboard without knowing what is wrong, just that it could be that.

Like you said it may just be a bad diode and all you have to do is replace it. The diodes used in the system are very common and easily obtained.

Or you can sell it as it is and let someone else deal with it while you buy a new one.
