Laptop charging circuit
Hi everybody first time poster
I have disassembled my HP Beats Envy 14 laptop to replace the back cover. On reassembly laptop no longer boots up (nothing happens at all). I've tested all the way to the battery board and voltage is ok. The charging pins however are only showing between 1.3 to 1.7 volts per pin on testing and I believe this should show around 12 to 15 volts - is this correct ? Want to be sure before buying a new battery board. Also I've broken the ZIF catch that secures the ribbon cable from the battery board to the motherboard socket. Could this be causing the problem ? The cable sits in the socket quite securely even without the catch. I've tried to locate a replacement ZIF catch but can't find any. If this is causing the issue it may mean a new motherboard which would be rather expensive for the sake of a ZIF catch.
