Since the original question in this thread was solved and my problem is kind of connected, I'll hijack it for a moment.
This is the deal: I received a brandnew PSP 3004 today. I just introduced it to my wireless lan at home, and naturally, I wants to update itself to the latest system software (6.00). Sure thing ... I thought. So I start the update, and the PSP downloads a 28 meg data package and beginns installing it. After agreeing to the TOS, when actually starting the install, the PSP stops and says "The battery is almost empty. Please connect it to the power supply. The update will start as soon as the necessary power level has been reached.".
Hmmm ... the battery is not really full, but not empty either, but anyway - if it wants power, it'll get some. So I connect the power supply and wait ... and wait ... and wait. The battery is being loaded, but the update doesn't start. Then, I aborted the update and started over again - with the same result: "The battery is almost empty.".
Then, I aborted again, switched it off and removed the battery to make the PSP run on power from the plug. It does that fine, too, but for some reason, it still persists that "The battery is almost empty.", even if the battery is lying on the table beside me. I found this problem once on the internet in a forum, but no solution was found.
Also, it doesn't matter whether I re-download the update or I start a previously downloaded version from the memory stick.
Anyone?
EDIT: I just found out that the battery symbol has to have three of three bars displayed (= be at 80% charge) for the update to work. Also, it seems it has to be in the PSP for the update to work. A safety feature for sure, but not programmed very well it seems. I'll keep you updated...
EDIT: false alarm! The system actually updates fine when the battery level reaches three bars. My confusion simply emerged from the bad wording of the problem in the PSP, which doesn't say that the battery needs to be inserted and needs to be full enough for 3 out of 3 bars.
