Acer Nitro 17 VN7-793G Black Edition Neptune_KLS Thunderbolt firmware
Hello,
does anybody have the firmware for the TPS65982DA conroller? Type-C 3.1 gen 2 and HDMI is not working. I have replaced Alpine Ridge controller JHL6340 so far (bought on Ali Express), since it had low resistance on one of the HDMI diff pairs. I tried the firmware from the VN7-792G, which has TPS65982ZQZR (different index!) onboard which at least has stopped hanging when restarting and HDMI started showing discolored picture on my monitor with DVI adapter (but no picture on my TV with native HDMI port). Would be glad if someone could upload working firmware, so I can proceed...

OK, I'll check what else could go wrong. Thanks so far.

Re: Bios request for Satellite P50-C-147 PSPTSE
Thank you ver much! But unfortunately the behaviour did not change. It stucks at 600mA consumption and no init.
All main power rails have voltage. I removed the audio codecs as it looked to me somewhat too warm. GPU and CPU power blocks are at 55° C. NVIDIA dGPU power rail has impendace of 10 ohm. Maybe its too low and the GPU is faulty...
Or do you have any further ideas regarding the BIOS?

This is the original dump. I tried to clean ME with ME/TXE Injector tool before without success......Last edited by Greg81; 05-11-2022, 04:07 PM.

Bios request for Satellite P50-C-147 PSPTSE
Hello,
I have motherboard DABLQMB16B0 Rev. B from Toshiba Satellite P50-C-147 with no init. I could not find any free download so far. According to a paysites title BIOS for following Models should fit also: PSPTNE, PSPTPE.
I tried the PSPT2E one I found on this site, but it did no work.
Does anybody have a working dump or even a copy of offical update?
Any help is welcome!
Thanks in advance!

Re: Laptop battery charging circuit
Hello,
I have a question to the following:
DCIN/VCC: input voltage from the AC adapter, should be close to AC adapter voltage
Does the input voltage always come from the AC Adapter? Is the charger IC inactive when running from battery? I was trying to understand the input voltage for Quanta FH5 mainboard, there seems to be no connection to the battery rail although in every IC charger datasheet you read about input from battery and in other schematics VCC is connected to the battery input.
