laptop won't turn on

hey guys

my hp laptop (15-af156sa) won't turn on. Took the back off to see if there was any obvious problem but all seems well.

The little led on the power jack is lit and when pressing the on button a little led with pwr led lights up for a few seconds then goes off but the hdd led next to it doesn't light up

everything seems dead no lights on the motherboard flash, fan doesn't start up. I've unplugged various things (hard drive, ram etc) and tried turning on again but nothing.

I've swapped the power jack to a new one but still the same problems.

any ideas what it could be ?

A free thing to try then try the cheapest part it could be.

1. Do a generic reset. No files are harmed.

2. The RTC Battery 697917-001 is just a CR2032. You as a tech would measure it and anything above 3.00 in circuit would be a pass. Else replace and repeat step 1.

3. The SERVICE MANUAL is at:

Using the service manual try it with just one stick of RAM, no ODD, HDD, SSD or WiFi to see if it will power up.

Remember I take it there are no other obvious signs of abuse or old big battery incorrect power adapter use.

tried all them apart from the round battery but still nothing

So is it worth trying the CR2032?

I do encounter folk that demand it be anything but. OK I get that. New motherboard it is?
