Laptop will not boot unless CMOS battery removed

[WallpaperMan]

I have a HP G60-126NR laptop. One day, it was stone cold when I press power button. I discharged the mothboard.  I then installed a new CMOS battery . I am using the power adapter to power unit. When I press the power button , I get nothing toally dead, except to show the power connection light. If I remove the CMOS battery, then discharge the motherboard again,  then plug in , and the laptop powers up without touching power button, and goes into setup screen to enter time. After entering time , it boots into Windows without issue. Windows SFC scan shows no error. If I shut down, not sleep, the laptop is dead again unless I discharge motherboard and start from square one. Also, I want to say that while Windows is running, if I close the lid to put to sleep, you can see that the screen is still active despite changing "what happens when I close lid". My diagnostics tells me it needs a new motherboard.

PS: I did flash the BIOS off of HP Website thinking it would  resolve my issue, but it did not ....

Hi @WallpaperMan ,

Thank you for visiting the HP Support Forums and Welcome. I have read  about your HP G50-126NR Notebook and having issues with the new RTC battery. You could reset the BIOS with this document selecting the reloading the BIOS default settings.

Please note remove any and all USB devices. Disconnect all non-essential devices, as these could cause some issues.

If it was the Motherboard the Notebook would not start at all. I would have someone check the battery. Hp part number from the manual  page 46, RTC battery 486624-001 as there could be a concern with it. The CMOS battery is  a Non-rechargeable silver oxide battery.

I hope this helps.

Thanks.

Good Morning, I replaced the motherboard. Same issues. I have concluded that the power switch is faulty and may have a short. I have one on order and we will see if that resolves the issue. The computer, once I reset clock, runs great when in Windows.

The issue has been resolved. The combination touch pad ciruit board for power and WiFi was broken and was replaced. Unit functioning normal.
