๐งต [Help] Acer Aspire 5 A517-52G โ Onboard RAM Removed, BIOS Mod Done, Battery Not Charging
Hi everyone,
I have an Acer Aspire 5 A517-52G-53NB laptop.
The onboard (soldered) RAM was faulty, so I physically removed the chip.
I also successfully modified the BIOS using the SPD Removal Tool โ the laptop now boots fine and works with an 8โฏGB DDR4 SO-DIMM installed.
โ System status:- BIOS mod is done (SPD removed)
- Laptop boots to Windows normally
- RAM is detected and stable
โ Problem:
The battery is not charging:- Power adapter

Hello Everyone
First I must say I am trying to learn electronics. I have an Acer Nitro 5. Board is LA-861P. The laptop does not charge but when it has battery life it would power on and work fine. I have use a multimeter to check the charger and I get 19v.
Input on PBQ3 mosfet is 19v but no output or very low voltage. The voltage on PCZ65 and PCZ48 is 2v and it keep dropping after putting the charger for a few second. Battery pin would give like 0.200v declining.
If I put the laptop off for like 2-3 months it would start charging again but I need to do this... -
This was a no power initially. Thanks to your help, I discovered it was the first mosfet, so I replaced. Now, the device will power up only if the battery is NOT connected. As soon as I connect the battery, it shuts off. If I connected the battery while the device is off, it simply will not respond to the power button. I replaced the battery, and while I suppose the new battery could be faulty, I'm assuming it is not. I'm having the same behavior with the new battery. I measure .2v at the charging coil. Manually applying power to the + and - at the battery header, there is no charging happening....

Looking for some advice on a 820-02016 board as I don't have much experience with these M1 machines. Learning the nuances of them as I go.
So the history of this machine was it had been in a bag where a bottle of water leaked. Presented as dead about a month ago, corrosion was mainly around the battery connector and it's sub-PCB. Some corrosion was noted on the board around UC300, CC325, CW1C7, CW1C8. That was it really.
Now without battery connected, USB-C will stay at 5V and cycle between 0 and 120ma. PPBUS_AON is cycling between 0 to 12.3V. If battery is connected,... -
Hi All, I am working on ACER Spin SP113-31-P6NZ ( board # Ironhide_APL 16835-1M) boots up well but does not work on main Battery & sometimes shits downs automatically. As soon as I unplug the Power adapter jack, Bang!!! it turns off. In Windows 10 it shows the battery is present & charging. I even checked the battery voltage by shorted BAT_G to GND & it shows 16 volts. Below I will share the voltages of the BQ24737 IC. What may be the problem & if anyone willing to share the Schematics, would be great. Thanks in advance.
These voltages are when the Battery is plugged...
