2020 MacBook Pro M1 bootlooping after repair.

[Gueric]

Basically, this never opened before MacBook Pro had some liquid damage around a few keyboard backlight components, that I replaced. Turns out it wasn’t the actual issue, the actual issue was a defective CD3217.

Removed it, replaced it. Laptop booted fine, I erased it, installed a new macOS version, checked battery health, speakers, screen etc. Turned it off to put everything back together, turned it on again, and it started bootlooping.

Chime, shows apple logo, then a progress bar, and when it fills at about 1%, reboots. Back to the Apple logo, progess bar almost empty,...

Hello guys,

I have recently aquired Lenovo Legion 7 16ithg6 NM-D721, with weird issue. From time to time it will POST fine, boot to windows and work without a single issue. After restart however, it will not post again and then it will not post at all.

After messing around with bios (reflashing it), removing ssd, wifi, battery, etc, none of helped, I checked 5v and 3.3 coils and to my surprise, multimeter showed both coils hovering around 4V for 5V coil and 2V for 3.3v coil.

Thermal camera did not showed anything hot, but I'm sure something is either going...

Hi guys i'm posting here because I think that there's a battery or BMS issue even do the problem is with a pure discovr smart speaker found with one battery at 1.6v and the other at 3.2 v not drawing any current from the type c port. The speaker was new and unused , my guess is that the BMS is somehow in protection mode or something, I have tried to disconnect the wires from it charge the batteries from the lab PSU and reconnect them and still not charging after that.What should I Try? I also bought another bms that you can see in the pictures but i have this white wire coming from the usb type...

Hi everyone,

I'm trying to recover a Fujitsu Lifebook E5513 (most likely 2023 model) that was bricked during a BIOS update. The update was interrupted (probably due to power loss), and now the laptop is stuck in a boot loop showing "PBB rollback" / "SBB rollback" messages.
BIOS access (F2) and Boot Menu (F12) are no longer possible – the system instantly reboots after the rollback messages.

I extracted the official BIOS update package from Fujitsu (contains FJNB2FD.CAP, ~18.7 MB) and tried tools like UEFIExtract, but it seems to only contain...

Hi All,
Anyone out there did any fault finding on the above amp with no reverb. I suspect the spring reverb tank is faulty but want confirmation before ordering a new one. Scoped that audio is present at the i/p to the tank (sinewave gets distorted when the tank is connected). I also injected a tone on the o/p of the tank which I can hear on the amps speaker.
Any advice appreciated.
