:rolleyes: i have a PGG-GRX570. the bottom of the computer says PCG 8A2L . . . it won't stay on and when you reboot it goes into hibernation mode and turns off. Comp USA says i need another motherboard because it won't get power from the power cord to keep the battery charged. any suggestions on how to fix this? does anybody know which, if any, other motherboards can be swapped into this unit? thanks!
