repair of HP65 - richard ask - 05-10-2006 I recently bought a HP65 in (I think) good condition. I replaced the battery pack with a brand new one, and turned it on. It started up and I played with it for maybe 10-15 minutes. Worked perfectly. Then did a small program, tested it, worked fine. Finally inserted a magnet card and tried to record data into that. Some mecanic trouble occured and a screaming sound (rubber wheel skidding?) Had to by force pull out the magcard. Re: repair of HP65 - hal - 05-10-2006 Hello Richard.
Was the new battery pack fully charged before you started using the machine? Also, have you tried operation with the AC adapter connected (with the battery pack in place!!)? The card reader draws substantial current even when working and a bad one can draw even more. It sounds to me as if the attempted card read took the battery down to below minimum operating charge. |
