Hi Nikko, I've got the same issue. If you confirm that the battery you are referring to works on other PSPs, you may follow the link below. Hopefully we'll find a solution ;) PSP working with power supply but functioning batteries not detected
I have made use of “ptest” (thanks Amir) and have been able to find interesting results… Test has been performed on the following devices using the SAME battery: (1) 2x PSP 2000’s presenting the issue (PSP works like a charm when connected to power supply BUT battery would neither function nor be detected in any way) (1) 1x PSP 3000’s not presenting the issue (battery detected and working) As you can see from above screenshots, in the case of the 2x PSP 2000’s, there is a battery detected and even charging, but communication between battery and device fails to establish. In this case, battery won’t be able to power the PSP. That may confirm a mobo/IC issue… perhaps the “charging IC” as shown on the pic below: Please let me know your thoughts if any, or if you’ve come across similar experience, comments would be highly appreciated!! :) Olivier
In my case I had used faulty 2 in one USB/power supply cable from geek.com. I noticed the psp charging light turned off 2s after I plugged it and that was it... As if it was not enough I hadn't noticed the issue at first and connected the cable to charge another PSP which as a result got the same problem... We have to be careful about cheap items from the internet!
