Things You'll Need
Instructions
Check the charger and the power cord for any obvious signs of damage. Plug another electronic device into the electrical outlet you've been using to make sure it works.
Turn on the PSP. Make sure that the power switch is not down in the Hold position. If it is, turn it off. Make sure that the WLAN setting is turned off. You cannot charge the console while WLAN is on. Check that the backlight is on. If it isn't, press any button to turn it on.
Plug the charger into the PSP and into the outlet. If the orange light appears, the charger is working. If the light doesn't come on, disconnect the charger.
Take the battery out of the PSP and plug the charger in. If the console works, the charger is fine and you need a new battery. If it doesn't, you need to replace the charger or try a new one to eliminate problems with the PSP. If a new charger won't power the console when the battery is out, you may have a console problem.
Borrow a battery and/or a charger if you want to double check what isn't working. If a new battery works with your own charger, you know that your battery is at fault. If a new charger works with your battery, you need to replace your charger.
