Things You'll Need
Instructions
Go to the "Settings" menu on the PSP XMB dashboard and select "USB Settings." On this screen, set the USB charge option to "On." Connect your PSP to the computer or PS3 using the USB cable.
Check the PSP's LED power indicator. If it turns orange, the system is being charged. Leave the PSP to sit and charge or you can turn it on and use it. The battery will charge either way though the latter option will slow down the process.
Monitor the PSP's charge progress. If you're playing it, the LED power indicator will turn green. If not, the LED will just go out when the system is fully charged.
