minus_13 Posted May 19, 2013 Share Posted May 19, 2013 Hi there. I have Mountain Lion on my HP laptop with sleep working (with open/close LID also) . My laptop is on AC + Battery Everyday but at nights ( The battery is 100% ) I close the lid and it goes to sleep and I unplug the AC and let it be on battery for the whole night ( At mornings I get 80% battery which is so far so good ). However last night I did the same but in the middle of the night the battery had compromised the plan and failed so the laptop ( I guess, because I wasn't awake ) died being on sleep mode. This morning when i opened the lid expecting it to welcome me warmly I saw it is turned off so I knew something was wrong. When I tried to turn it on it didn't on battery ( No reaction to the power button ) but It turned on on AC but it didn't even display the HP logo at the very first and so It was broke. I assumed it was the LCD dying but it wasn't. After so many ways ( Hard-reset using power key, trying to boot into OS blindly, ... ) I finally solved it by opening the laptop and forcing a CMOS Reset by removing my BIOS battery and RAMs. So It turned on this time and displayed me a message saying that the CMOS checksum is invalid and so we need to reset the CMOS I preesed OK and it restarted and everything was working fine again however I noticed that I have a problem with my battery. On Windows it says 0% plugged in, charging.. but it won't charge. for 2/3 hours the battery level is the same 0%. I tried flashing the bios again but it didn't help. Any ideas about this?

minus_13 Posted May 20, 2013 Author Share Posted May 20, 2013 Does the laptop has Nvidia graphics by any chance? I love HPs with failing Nvidia chips Yes the laptop has a nVidia GT 230M 1024mb in it with no on-board cards. It took me 2 months to figure out how to make that card work! Problem with GT230M on a 10.8.2 HP Laptop - nVidia - InsanelyMac Forum Link to comment Share on other sites More sharing options...
3.14r2 Posted May 20, 2013 Share Posted May 20, 2013 Yes the laptop has a nVidia GT 230M 1024mb in it with no on-board cards.That's not what I thought. These were 7xxx/8xxx series chips. Even MacBook Pros suffered from the issue. Link to comment Share on other sites More sharing options...
