This fix was a lot more of an inside cleansing position than repair. Tremendous basic to do, presented you have the correct screwdriver to take away the cover. The concern started off off intermittent and not very long later on, it would not charge. Cleaning exterior contacts with Alcohol was NOT successful.

Methods: shut off gadget, Eliminate deal with and gentle clear the contacts if you see corrosion. I utilised a pair of curved tweezers. Shut up (no screws) and check out if it charges. If it does, reinstall screws.

Note- I did put a meter on charger contacts initial to make sure there was ability, which there was.

Hope this assists!
