HP Omen 17 cmos

[Bostav]

Does the hp omen have a cmos battery? I'm trying to get fix my laptop after I updated it. The caplocks key blinks 5 times slowly and 3 times rapidly. I've removed my ram and placed it back, held windows key and b (v) but to no avail so I'm going got a cmos reset only I can't seem to locate it.

Hello @Bostav 

It all depends on what model number you have.

Please post that, or the product number so I can look up its manual.

You can run the HP Support Assistant to find the Product number.

On the bottom of the laptop it says 17-an010ca

OK thanks. Looks like that motherboard does not have a cmos battery.

You could go into the bios and use F10 to reset bios, then F10 again to save and exit.

You could also disconnect the power cord and the main battery to remove power to the board for 5-10 minutes to do the same thing.

Thanks! Unfortunately, I'm unable to access the bios due to the boot sequence never reaching that point 😞 I've also tried discontining the power and main battery for about 30 minutes but didn't have any luck.

If you rapidly tap the ESC key during Power-On, do you get a menu of options?

There you should be able to choose Bios from F10 at that point.

Does the bios open then?

To add, can you try disconnecting the hard drive before attempting to access the bios? see if that helps.

[Bostav]

Negative,  still seeing the same results. Black screen with a flashing caplocks. 

[Photoray002]

OK. The blink code indicates... The embedded controller times out waiting for the BIOS.

Usually a motherboard failure, but sometimes a hardware failure.

Hopefully you are still under warranty?

[Bostav]

Warranty expired in 2019, Oh no! Is the embedded controller soldered on?

I couldn't say for sure, but its very possible.
