You're a legend.
BQ24780S is the original IC and I was replacing with BQ24780.
I found the exact suffix with S and replaced.
Laptop is fully operational.
Thank you very much.

HP Victus 15-fa1024nt - DAG3PAMB8D0 REV.D MODEL: G3PA
Hi, everyone.
I need help with this repair, please.
This laptop came with no signs of life.
There is no orange/ white light on the charger.
The only voltage present on the motherboard is 19V.
After inspecting it with a thermal camera I found the charging IC (ISL88739B) very hot.
Pin 21 shorted to ground which goes to the date to the mosfet next to it.
I've replaced it with another ISL88739A and the short is gone it started to get an orange and white light on the charging port.
5V present
3.3V line not present. The IC on the picture RW=9J... -

Re: G7a-2g da0g7amb6d1 rev bios needed
Hi, good afternoon all.
I need help, please.
The laptop came to me with no display and a 5.3 code on the caps lock.
Found 3 pins with soldering broken on the RAM slot. I've soldered it, but still has caps lock flashing.
So I decided to flash bios.
After the first attempt, it stopped flashing, but no display.
I've tried about 6 attempts of flashing BIOS I finally got it to turn on, but it takes about 1 minute every time I turn it off and on.
I guess maybe BIOS firmware is still not compatible....Leave a comment:

Crucial X8 2TB Portable SSD External Hard drive
Hi, everyone.
I'm trying to fix this portable external SSD.
It suddenly stopped working, according to the customer.
After diagnosing it, I found this IC in the picture shorted on pin 5.
It's a High Voltage Boost Converter (PS6117-40).
I can't find any datasheet for this specific IC.
I found a similar one, TPS61175-Q1, but the pins don't match.
Can you guys help me find where I can buy it?... -

HP ProBook x360 435 G7- PRIMROSE-6050A3154701-MB-A01 (A1)
Hi, everyone.
I need help on this one, please.
Liquid-damaged motherboard.
After reflowing the corroded areas and doing U.S cleaning it still won't turn on and there is no light on the charger.
The problem is that I can't find schematics. 3.3V LDO is up, but not the 5V LDO. The IC that created the 5V line is AKLM 161 and I can't find a datasheet for this IC.
Thanks All.

Acer Aspire v5-572 Quanta ZQK DAOZQKMB8E0
Hi everyone.
Trying to fix this laptop that works intermittently, when it turns on works absolutely fine if it shuts down and disconnects the charger it will not turn on unless the screen cable is reset.
I've tested with another screen and had the same issue.
I have the schematic for this. Can someone share the board view? Please. -
A1990 Constant Kernel Panic: AMDFramebufferVIB::setPowerState
Hi, I have an A1990, i9 & Radeon 560X. Before it was freezing every few seconds, almost as if failing SSD, even on external macOS installation. I have tried a clean reinstall, revive + restore T2 firmware and it now works fine, other than it seems to kernel panic after some time in sleep.
Below is the kernel panic log, its similar to a lot of posts online for the same model, with no comments on how to fix the issue, and whether its firmware related or an LB issue. Most seemed to happen running Catalina but I am on the latest version of macOS Ventura.... -
