Auto-Shutdown Issues

[gymnotropic]

Hey,

I've looked around a bit and I've been unable to find a solution to my problem. My PSP continually automatically shuts off (you know--with the low battery icon?) This wouldn't be a problem... if I had no battery life left. The problem is, it does it when I have a full battery. Or well, to be more precise...

From 91%-100% or so, it hardly gives me the message.
From 81%-90%, it gives it a bit more often.
etc, etc...
At 21%-30%, it won't stay on for more than a few seconds.

Is my battery dead or something? It only really started doing this since I upgraded to 3.71m33.

P.S.:
There may also be some ratio between the time it is on and the time it is off.

Interesting, my PSP exhibits similar symptoms.

Do you know when the problem first started occuring? Could you provide more detail as to exactly what you did?

[gymnotropic]

Well, as I already stated; It's been happening since I upgraded to m33. I had been using 3.40 OE. I think I downgraded to 1.50, then upgraded through the different m33 versions. Or something like that.

Come to think of it, my PSP battery seems to be doing the same thing, but not as severe. :(

[EvilSeph]

I guess I should have been more clear.

Could you both tell me all the details about your PSP?

Current firmware?
Firmware history?
TA-082? 086?
etc.

Current: 3.71 M33
Firmware history is not much to note, was on 3.52 m33 but this started when i upgraded to 3.71
TA-079 I think
I think it's stopped the shutting off thing now, battery kinda reads wrong (is 100% 3 hours?)

[gymnotropic]

Hmm... not certain about all the details, but I can make guesses.

Current firmware is 3.71m33-2, I believe.

1.50->2.01->1.50->2.71 SE->3.xx OE->3.40 OE->1.50->?

? = upgrading to 3.71m33. I don't recall right of what exact firmwares I used, but I think I upgraded one-by-one through the m33 firmwares.

I don't know what motherboard my PSP has. But I do know it uses the motherboards that the released v1.50 PSPs used.

Well, I know that the problem is not caused by a battery for me, since I have two and it happens with both.

Try placing your battery in the fridge for a bit, cooling a li-ion battery makes it more lively.

Nothing bad SHOULD happen but I can't guarantee anything. I've done this to many of my batteries for different devices and it works.

[gymnotropic]

Well, I put it in the fridge, and it's still acting up.

At 1:20 PM, I put back in the battery and loading GTA. At 1:45 PM, it started acting up.

Not sure if that helps at all, though.
