I use my HP Ipaq H5550 to tune my acoustic piano. The software will only run on this model so I need to get it working.
The HP charger is 120/240V to 5V dc 2A. Recently it stopped charging and the iPAQ battery is completely flat. On checking the charger output voltage I noted that it was only a few millivolts d.c. However on switching my UT70D meter to a.c. it reads 3.5V.
Can someone explain to me why I see an a.c. voltage at all?
Unfortunately this is one of the friction welded plastic cases and it probably is too much trouble to open it.
