Hello, I would like to share Abir x6 vacuum robot cleaner rom files that I extracted from SPI ROM chips. One chip is on main board and another is on camera module (the problem with robot was in camera rom, after re-write with other robot's rom it started working perfectly fine).
Maybe this will help you, because I couldn't find it anywhere.
Camera Dump: 4MB
MB Dump: 2MB...

Asus X552C(X550CL Rev 2.0) onboard ram disable
Hello, I would like to share info about onboard ram disable for asus x552c board x550cl rev 2.0.
Since I couldn't find anywhere info for the configuration of pcb id's, I had to try for it to work.
PCB_ID0 - LOW (moving resistor from R2422 to R2424 close to pch)
PCB_ID1 - LOW (other side of the board, move R2423 to R2425)
PCB_ID2 - HIGH (R2433 was the position but if there is no resistor, move it from R2432 close to pch)
All of the resistor values are 10kOhm in 0402 size.
I hope this helps!... -
Re: ASUS GL553VD-Will it work from dc supply??
It should power up, I think the problem is in graphics chip, since of the asus poor design. I am not a pro, correct me if I am wrong. I have tried on bunch different laptops that use more power than DC lab psu and they powered on, since you are not using full power on start up like lenovo legion y520 uses about 0.8 - 1.2A just for idle. -

Hello mcplslg123, do you mean these fets? I thought about them, and haven't check them yet.

I have tried 3 different chargers, all the same. I have ordered another motherboard and will try to identify the problem, will see if it's the battery fault which I think is not faulty (because it works fine, discharges, can charge it normally with PSU).Leave a comment:

Re: HP Pavilion 14 chewbacca_14_u_uma battery charging problem

Re: HP Pavilion 14 chewbacca_14_u_uma battery charging problem
Yes, it works from battery without AC, it discharges as normal, but when connecting the AC it does not charge just stays same percent as if it starts to work from AC only....Leave a comment:

Re: HP Pavilion 14 chewbacca_14_u_uma battery charging problem
ACOK should be 0V since its inverted signal, when removed AC - it goes to 3.3V
Correct me if im wrong.Leave a comment:

Re: HP Pavilion 14 chewbacca_14_u_uma battery charging problem
This battery was charging before, it charged once to 97% percent, everything was fine and after trying to charge it for second time it didn't charge at all.
I have 2 batteries from GREENCELL, both of them are non working.Leave a comment:

Re: HP Pavilion 14 chewbacca_14_u_uma battery charging problem

The charging chip is BQ737.
Voltages (battery plugged in):
1. ACN - 19.66V (19.6)
2. ACP - 19.65V (19.6)
3. CMPOUT - 0V (0)
4. CMPIN - GND
5. ACOK - 0V (0)
6. ACDET - 2.61V (2.61)
7. IOUT - 0V (0)
