Product: HP ProBook 640 G1 GE46UC
Operating System: Microsoft Windows 7 (64-bit)
Hello Everyone... since this is my first post/ first Hp Notebook , I thought I would ask a couple of things. so please bear with me 🙂 1: The notebook powers off on battery anywhere from 80% down to 10%. also reboots and powers off constantly on battery, also the Bios date and time reset to 1999,when all power is removed. . windows also said the computer date and time is wrong when its on the power cord with battery in but shows correctly . T he Hp Diagnostic software said everything "OK" on the battery check running 4 times. Complete system diagnostic is "ok". all drivers and software updated (July 31/2019) . 2: The Windows 7 64 bit Professional restore image I made f rom windows backup/restore feature will not go back in to the 250 gb ssd when I tested it nor on the 1terybye mechanical drive . The notebook is out of warranty and I have had it fro 30 day's. Help.. any thoughts ... thank you a head of time. Bruce

it seems as if the overall problem is with the date/time kept by the BIOS... that affects Windows as well... I would replace the  real time clock battery... not a trivial thing, but doable
