thank you. I have tried the bios and the physical state is different, it still does not give an image. But, the fans now do not restart, they remain spinning constantly. I also notice that the Integrated U91 (chl8104) is overheating abnormally, probably short. open any equivalent to that ic?...

Hello sir, thank you for your comment. These are my files, I also cleaned the ME, it's just fans spinning without video. This board always needs a GPU connected. Same status, no video....

I need bios for DP67BA INTEL BOARD
Hello everyone. I have this board from a colleague, with a short in O2U2 GPIO, it was replaced. But when you turn it on it turns the fans at times as if it wants to display video on the screen, but the loop restarts. If someone has a backup it would be great.

Has anyone had a similar Dell model happen to them? The rtc_soc part was checked and it is at 3v, that is, rtc power is on, and also rtc_det# remains at a high level, because although these signals are there, it does not detect the bios battery. At D1 the cathode output is approximately 3v. The diagnostic LED flashes 3 amber and 1 white. According to the Dell manual, it says it is a CMOS battery failure.[ATTACH=JSON]{"data-align":"right","data-size":"custom","height":"239","title":"l.png","width":"500","data-attachmentid":3238075}[/ATTACH]...

hi, sir. I have a DELL inspiron laptop in service from a distant company. The "service etiquette" is in absolute deterioration. I have two saved bios, apparent corruption. According to the rules, I can't upload without the serial.?
Can someone help me discover its exact model?[ATTACH=JSON]{"data-align":"left","data-size":"custom","height":"196","title":"b.png","width":"400","data-attachmentid":3234983}[/ATTACH]...

Please I need to clean the ME region, LAPTOP HP CK0010LA
Hello guys, can someone help me clean ME region?
Board model: Granger-6050A2977601-mb-A02
Laptop model: 14-CK0010LA
I have extracted the bios from the original HP firmware and also made a backup from the chip. But I haven't been successful in both.
There is no upload option on the page yet

It seems that the problem is connecting the ram. I have tried several rams but the device turns off, it only lasts 10 seconds with an average consumption of 415mA, then the device seems to protect itself at 36mA. Now where to measure this piece of vegetable? In the meantime I will measure the RT3602AE ic to see if something is wrong with the cpu. I need advice.
I am guided by this similar schematic: [URL="https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/schematic-requests-only/106497-granger-6050a2977601-mb-a01-schematic?t=121493&highlight=6050A2977601"]GRANGER-6050A2977601-MB-A01...

Hello Sir mcplslg123, DDR4-DRAM RST# pin at 1.22v when powering on with a consumption of 451mA on the board, there is also VTT 0.615v. I am also noticing that the machine turns on for only 10 seconds and drops to 36mA in consumption. I will try with another ram, since in the VDD RAM coil the resistance is very very low, 2 ohms. I will comment on the result....

Hello, I have a similar model, it is 6050A2977601-MB-A02. Although they have the same KBC, it has video integrated into the CPU. I'm checking and there is no VCCGT either, but there is a very low resistance of 8 ohm at the output. Would it be too low for that line? Or will the integrated U66310 (SIC534) be short circuited? Note that the DRVEN or ZCD-EN# pin remains at HIGH LEVEL.

Thanks sir, I will check this option. Although there are few followers of that store, I doubt it is new, but I will take this machine out of the trash....

Identify and optional replacement ic max17035 charger. Laptop 6050a2357401 satellite toshiba
Who has replaced this old astronaut?
ic burned, holey. I have a BQ24168, it claims to be a customer replacement, but it is not. It seems that no matter how old it is, there is no stock at the distributor.

Another suggested measurement is, EDP_VDD_EN but this remains at zero volts. Does anyone know why it is null?
also BL_EN: 0.33v very low for this line.
quarz oscillators in good condition.
Basic low consumption processor, N2830 Intel.
