4.01m33-2 battery charging issue?

Well i'm on 4.01m33-2. I was playing an ad-hoc game of the Punisher on CPS1PSP and it gave me a warning that the battery was low and needed charging. I plugged it in and the orange light didnt come on, and the notice didnt go away. The battery level didnt go down any further however. Then once i exited the emulator it began to charge and the power light changed to orange. Any thoughts...?

Its because you were using WLAN, which takes up 1.7x normal battery power.

still, does the light not change orange?

Your PSP doesn't charge AT ALL if you're using WLAN.

Yepp, so even if you're using WLAN, and plug it in...the litttle orange light will not turn on.

Oh ok, i guess that makes sense...

i never had that problem. i used to have Monster hunter parties with a few friends and we used to use it like that and play for like 30 hrs. or more.
