Hi, everyone.
I have this notebook that won't charge.
In Windows, the charger icon doesn't appear on the battery, but the charger turns on the notebook normally.
PU301:
Pin 5 (ACOK) - 5.97v
Pin 6 (ACDET) - 1.83v (should have 2.6)
Pin 16 (REGN) - 6v
PQ308 has no gate voltage, so it doesn't drive PQ309 low
With the battery connected, its voltage goes the reverse way to the jack, having 14v and not 20v:
PQ301 e PQ302
Pinos 1,2,3 14v
Pino 4 5v
Pinos 5,6,7,8 com 14v...

Looking for a BIOS dump. From HP site it looks incorrect to flash.
See attached (corrupt?) Bios dump.... -
Hello guys!
Please, I need to reset my Latitude 3420 BIOS password. I'm new to this and I want to know the best way to get the dump for you. I have access to the O.S. (Windows)
Thank you very much! -
Hi,
I'm having some issues with a Dell Latitude 3420 laptop I'm working with. The chip itself is an XMC25RH256CXIQ but I've not been able to find the exact settings for this chip using NeoProgrammer.
Instead, I've made a dump of the image using the following three chip settings within the software:
- XC25QW256C
- W25Q256BV
- MX25L25635E
All three images have been uploaded. Oddly enough all three images aren't identical, but I'm guessing that the XMC XC25QW256C version might be the closest match.
If someone... -
i bricked my bios using the smokeless umaf tool and trying to tighten ram timings. i purchased a ch341a programmer and made the mistake of not backing up my bios before flashing the stock bios on the chip. i tried injecting my serial and all in the bios and then flashing but now the hdd light just blinks when powering on and nothing else. ill attach the firmware i flashed to the chip and the default i added it to. also the chip is a winbond W74M25JWEIQ. my serial is N2NRKD019645059...
