Dear Members,
This laptop used to work with a 19v 3.4A adapter.
After 4 years of using it, now, the adapter's output voltage drops to 17v when windows loads up. Then the laptop suddenly turns off.
Today, I have connected a 19.8v 4.5A adapter to this laptop. Then the adapter's output voltage dropped to 19.4v but the laptop worked fine.
In addition, I noticed that the cpu power coils get warm to about 50'C but the mosfets are cool.
All the voltage rails on the mainboard are fine without any reduction except for the 19v rail. All the ICs and coils on the mainboard are...Today, 01:36 AM -

This is a list of compatible laptop motherboard information that I have been collecting for some time.
And it's still ongoing.
Every time I come across information that a board is compatible with another, I write it down.
Anyone who wants to, can continue to expand the list.

Hi,
I am looking for the schematic of this motherboard or this component, PQB4 reference (Unable to read the text beyond P5)
Also, if someone with experience could tell me, why would this component burn in order to avoid this happening again?
Thank you.Yesterday, 02:38 PM -

Hi !
I wish to know how to remove SVP from this model with I7-8565U CPU.
Try already the MEC method, read EC-erase-wait5 min-write back but password remains.
Obviously the Lenovo Autopatcher not working for 8th gen CPU.
So how to do it?

Hi all,
Model: HP Pavilion 14-ce3010nh 8BV97EA
Board number: DAG7ALMB8C0 - G7AL REV C
Issue: I have an HP Pavilion 14-ce3010nh 8BV97EA laptop. When plugged into the charger, it turns on, but there is no display, the fans do not run, and the processor gets slightly warm. Unfortunately, I haven't been able to figure out what the problem is. I've reflashed the BIOS twice without any success. No post. Already tried out with another ram stick with no luck
I measured the voltage with the HP turned on in red, and I measured their resistance with the HP turned off in green....Yesterday, 04:10 AM -
