See attached.
Measure the voltages on the DCIN mosfets and post their readings.
What is the history of the unit ? Any liquid damage ?
Just started to fail one day under normal use ?
Are you using the original power adapter ?Attached Files -

Re: Hp la-c701p no display
Can you post the DC power supply reading?
If there's voltage on the ram coil for some seconds before it goes off since you need the s4-s3-s0 then check accordingly.
Check if the slp_s4#, slp_s3# and it corresponding voltage like the susp# etc is generating and also check your DC to DC section.Comment
