The laptop will only power on using the power cord but if i remove the cord the laptop will continue to run on battery power. I tested the battery using the HP diag tools and it passed. I bought a new battery and still have the same problem ( i tried 2 different new battery's). If i remove the battery and hold the power button for 30 seconds, install the battery it will power on properly but only once. So, i decided to re-test it and now it shows no battery even when I'm running on the battery. It has the latest BIOS update, and it runs great otherwise.
Thanks
