- Topic title should contain: the device's manufacturer, full model and the brief description of problem.
- Topic message should contain: the PCB marking code (required in case of hardware repairs), an extended description of problem, things you have checked/replaced/measured, your conclusions and the question. If you are not able to find the PCB marking code, please read THIS TOPIC. If you still cannot locate the PCB markings, please upload a clean, both-side photos of the mainboard - it is required to remove any films, modules or brackets possibly covering these markings.
- Before posting a new topic please read all topics in TRAININGS subforum and make a preliminary diagnostic based on the content of those trainings.
- Uploading of any complete schematics, BIOS / firmware files or any other kind of documentation, or linking to 3rd party websites with such files, is STRICTLY PROHIBITED. You can only upload the small portion of documentation or, link to BIOS file on UNVERIFIED BIOS FILES subforum, which simplifies the diagnostics/repair. You are not allowed to upload more then one complete page of instruction/schematic per single topic. The file you upload must not contain any watermarks, "confidential" markings, links or email addresses and cannot be password-protected.
- It is only permitted to describe one faulty device per single topic - you should always open a new topic for each subsequent device.
- Requesting of the full schematics, BoardView files, BIOS files or any other kind of documentation is NOT ALLOWED in this subforum. If you need to ask for any of these, you should open a new topic in DOCUMENTATION/BIOS REQUEST subforum.

What do you mean by that? Did that coil burn, or was it physically ripped off the board?
While the laptop was working, it suddenly stopped charging. It ran completely on battery power alone. After removing the rear cover, the choke was glued to it from the outside. It is swollen and overheated.

PC8214= 10µF/25V, package 0603
I thought so.

Remove the damaged capacitor PC8214 from the board and measure the resistance to ground on any pin of resistor PR8201.
If the resistance is high (in kΩ range or greater), solder a functional capacitor and coil that burned and test the board.
PS: Edit your first post with the motherboard marking code according to the moderator's request, otherwise it will not ends good.

Resistance measurement at 400 kOhm on both sides of PR820.
A new capacitor and coil are scheduled to arrive tomorrow. I will let you know about the results after soldering.
After replacing the PL8200 2.2uH coil and the Pc8214 10uF/25V package 0603 capacitor.
The laptop is working properly.
Thank you for your help.
