Batteries Not Working At All...

[Azure]

My GP32 stopped booting up with batteries several months ago and only works with a PSU. I've tried numerous different batteries (Made sure they weren't dead a million times) but none worked. I opened it up and looked around but I couldn't find anything wrong. Any idea on what might be wrong or what I should look for? Here are the best pictures that I was able to get:

See anything wrong? Thanks for reading.

EDIT: BTW, it's a FLU.

The only times I have seen this happen is when people report accidently running batteries and a PSU at the same time, seems it does no harm on some GP32's but on others it causes this strange problem.

I had a little casio keyboard did the same thing.

I guess the PSU uses a different circuit to the batteries.

Follow the wires and check the connections.

Wiggle the wires with batteries inserted while switched on.

EDIT: I have an FLU bought 2003 and I've not had any trouble running from a psu with batteries in. Bought mine from craigix too.....

The psu jack has a switch in it that switches off the battery circuit, and this switch can become loose. Some people have stuffed their psu jacks with paper to fix this.

My GP (a Blu+ from GBAX) did the exact same thing! I had it plugged into the wall while it had batteries in it. Once I unplugged it, it wouldn't run on batteries AT ALL! I tires everything I could think of but it would not run. So I purchased another one. A day or two before the new on arrived my old one decided to run on batteries again! I was pissed!!! Why would it do this? Does anyone know?
I havent had any problems with the old one since then but I am glad I have two now so if one gets messed up I have a back up.

To anyone who is having the same problem I have no real advice except maybe it will all of a sudden start working again so keep playing with it plugged in (w/o batteries) and checking it with battieries.

Anyone who has any idea what is going on please let me know. I am scared to open up a perfectly (or in the case of my old one - not so perfectly) GP32 to figure out what might be wrong.

Thanks!

Well, I've accidentally used the PSU with batteries already in the GP32 numerous times but it never caused any problems.

Have you got a multimeter? You could test the continuity on all the contacts right back to the board then...

Some one else had the same problem a wile back he/she(idr) found that if u took a small chunck of paper wraped it around a tooth pick or some other small thing to make a small cylinder and slyped it in to the psu port then it would work on battrys again.

EDIT: I found the post here

Yeah, like I said, but if you're too lazy for that, you can test if that's the problem
by plugging the ac adapter into the gp32, with the adapter unplugged from the wall, and the batteries in the gp32.

i go along with evildragon. find someone with a multimeter who knows about electronics...

gamepark fucking suck at electronics design... i mean... you plug an adaptor in with the right voltage but wrong polarity and it fucks the lot??? any sensible manufacturer would have put a diode in so that this can't happen...

but we all know gamepark aren't sensible :S


hope you get it fixed, anyway...

I tried the paper idea but it didn't work, but then I just got a toothpick and started poking the little pin and I got it to work. Thanks anyways. Now I can finally play R-Type on the go, again

*Supreme Bump* This thread helped me out massively over the weekend. Just wanted to add I used a metal spike tool to bend the DC pin, it then worked again with batteries <phew>. I'm not using my AC adaptor again!
