by ResoluteHawkI have an Asus G14 (GA401QM) that has a power issue. Originally the board had a shorted 5V rail and dead EC. I reballed a working EC, soldered it on, and I resolved the 5V issue by replacing the APL6012 and the low side 5V mosfet. Resistances on all power rails are healthy now, but 20V does not make it through the first MOSFET. 20V is present on the drain of the first MOSFET, but there is no voltage on the gate or source.
When diagnosing this issue, I thought that the issue was due to the BQ24800 chip not outputting the correct signals so I soldered on a known working chip and the...05-08-2024, 01:30 PM -

by johnbetonHello,
I have a A1706 with 820-00923-A board. The laptop came in with non-working keyboard. I bought a new top-cover with keyboard and transfered everything to the new topcover.
Since then the macbook will not charge or power-up. Before replacing top cover, I started the macbook to test, and it worked fine apart from keyboard. Then shut it down and did replacement.
This is what I measure so far:
Resistance from F7000 to ground is 123 Ohm on pin 1 and 2
PPBUS_G3H = 0,79v
PPBUS_HS_CPU = 0,79v
PPBUS_HS_OTH5V = 0,79v

by dcbwThe PSU works, but shortly after powering on (either in the G5, or by shorting the power-on pin to ground) it begins buzzing loudly. It also makes the LED lights connected to the same circuit flicker. It's definitely a buzzing, not a high pitched whine.
The buzzing seems to come from the high voltage side of the board, perhaps from the white relay. Could the relay be bad, or could the 5V supply be bad enough that it's unable to keep the relay on? Any pointers to help isolate the issue? Thanks!

by caspianDear 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 -

by NagyeszHi 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 -

by Stefan SteffHi !
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?
Thanks-
