This audio chipset has been a pain to deal with, most of the time its impossible to find drivers for chinese laptops that have no name/brand, or generic rebranded laptops.
Huawei also started to use it BUT they no longer host drivers on their website since they want you to force their PC manager app that often refuses to install after bios flashing and apparently the generic drivers around wont work on some intel systems and others wont work on amd systems, the generic ones have worked only once and i think i have had this problem on 30+ laptops so far in the last year.02-21-2025, 12:33 AM -
I have try with 3 different adapter
Dell adapter 40w - warning "Slow Charger" (charge rate 8mW)
Dell adapter 65w - warning "Slow Charger" (charge rate 8mW)
Power Supply Connected with BY-3200 (in bios detect 65w) - okay and no warning (charge rate 25000mW-32000mW)
i already tried update bios and update all driver but problem still persist....any idea to solve this?... -
Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages
The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

For the second time this week I received a Lenovo laptop with onboard ram and one sodimm slot. Both laptops run stable from their onboard 4GB RAM, but turn out to be very unstable when there's a sodimm inserted in the slot.
Both times it was a GS44D/GS54D NM-C711 rev 1.0 board.
Both times there were no loose pins on the slot and it did not matter what sodimm I put in. It just artefacts and crashes randomly when there's extra ram.
What I did notice is that almost all coils have very dirty phases one the mosfet side when checked with an oscilloscope. Not something I see very often....06-07-2024, 09:16 AM -
Hello Everyone,
I am looking for schematics of good quality laptops and tablet with 11th gen CPU.
I'm an engineer and I'd like to study them.
I can find:
- Macbooks
- Surface laptops
Does anyone have any schematics of 11th gen Dell XPS laptops, or other good-quality premium laptops and tablets?
it would be much appreciated!02-08-2022, 07:28 AM
