I did the following Bios update, seemed to work fine for a couple days, until again I drained the battery! would not charge it, or turn on with battery out and power supply plugged in.
I did find a solution that is frustrating to understand why its like this~!
Have to have the lid / screen closed on the laptop. plug in power supply, then unplug where the power cord connects into the power supply ( the 3 pin that plugs into the HIPRO block) and wiggle its around and plug and unplug untill you hear some sparking sounds! The battery light on the laptop should eventrually flash for a split second , and you hear a power surge sound from the laptop! Make sure to fully plug the power supply, open up lid and it will power up fine.
I have tryed an aftermarket power supply unit as well, and still didnt solve the problem.
I know this procedure is un-sound, but its the only way I can get to power up my unit with the power supply. Doesnt seem to be a BIOS problem, but an internal issue to sensing (seeing) the power supply, until it gets some sort of voltage surge.
It runs and powers up fine with just the battery all times, just when I want to plug in the power supply I have to run this procedure everytime. i've been doing it for over a month and im getting very tired or messing around with the power cord for like 5 min until I see the battery light flash and then I can turn on my computer.
Any ideas or do I need to call for warranty work, which I dont want to do since it will slow down my progress with my project.
Thanks for any advice other than flashing the Bios with 3309 which I already did!
