Pavilion will not boot after bios update

[seilermike]

I have an HP Pavilion 11-n010dx x360 that would not boot if plugged in after a normal shut down.  If it was not plugged into power, it would boot just fine.  

After troubleshooting on these forums, the next suggested thing to do was flash the bios.  So...I downloaded the bios and went through the normal on-screen prompts and flashed/updated the bios.  

Now, it will not start at all.  When I turn the power on, it never even gets to the pre-boot and bios.  I found where there is an emergency bios recovery by powering off the notebook.  Then press the "Windows" and "B" keys at the same time and then turn hit the power button for three seconds.  Well...No love.  Another post said for newer notebooks, to use the "Windows" and "V" key instead...Still no love.

Are there specific buttons to do the bios recovery?  Or, another method for HP Pavilion 11-n010dx x360 notebooks?

Any and all help is greatly appreciated

Hello;

Allow me to welcome you to the HP forums!

I don't know if this will work, but it's worth a try:  http://support.hp.com/us-en/document/c02693833

Thank you but...Still no love!  

That link was where I found the pressing the "Windows" and "B" keys...

I figured it out...

To reset the bios on this HP model, holding the power button for three seconds and the "Windows" and "B or V" keys at the same time until it goes into the bios to reset will not work.

To reset the bios, I unplugged everything,  removed the back cover, unplugged the main batttery and then unplugged the RTC (real time clock) battery, which on this specific make and model doubles as the CMOS battery too.

In unplugging all power for two minutes, it resets the bios back to the factory bios.  I plugged the batteries back in, reinstalled the back cover, turned it over, hit the power button and BINGO!!!  Back to normal!

Here is the link from HP on how to remove the RTC/CMOS battery.

Good luck to anyone else having this issue...I hope this explanation helps!
