Unfortunatly with the end of the containement here in France, I will have less time to spend on it... So I might buy a new MB, and I will tell you how it works. Thanks again for everything, that was very helpful and I learned a lot

Hi ! I had the mod made, and followed the guide. Very clear, thanks for that I create a backup file: https://easyupload.io/cpc6br When I tried to write the file @lga1156_ftw sent me ( with cleared ME ), I had an error. So I unplugged everything apart from the clip and did it again. Always...

Ok.. Plus I touched the MB a lot during the process, could have cause electrostatic discharge etc... I feel like this reparation might be too hazardous for me :sweatsmile: Is it worth to try just flashing the bios ? Just too see ? To be honest if I could pay 250e for a new MB and get it for...

I can't find the exact same model ( apart from some websites, offering it for around 900€..) But I found some of the same series. It should be compatible, as everything apart from SSD, screen, fans, touchpad and keyboard is directly on the motherboard. For example there is this one ...

Some news. I got the mod made on the programmer, so I will probably try it in the next dew days. For the bga chip, I received 2 positive answers. It would cost me between 60 to 90 € for the replacement, chip excluded. I would do it without hesitation if we were sure it could solve the problem...

Hi have contacted several repair shop, but they all say that this is a bga chip, and the replacement is too difficult for them ... Maybe the french repair shop are not as skilled as yours :sweatsmile: To be honest I don't see what I can do now, apart from buying a whole new MB... Especially...

I visited this website, no service dealer in France ... I will go to visit a repair shop

Thing is, I can't find any authorized repairs shop on the HP Website that is located in France.. But I am going to try to flash BIOS, and ask if a repair center can changed the KBC for me, and I will see. I think there is nothing more I can do with my own gears and skills

I think the best for me is to make this mod https://abload.de/img/3.3vfixq5cpf.jpg Then, I received the bios file, but do you have a guide or something which explains how to use the programmer ? About these observations, nothing we can sort out ?

I was talking about the mod to transforms 5V into 3.3V on the programmer. To do so I do need to solder a thin cable right ?

I will try that, but as I said, I do not have what is required to do soldering. I am going to try to find it by asking to some friends, but I am not sure I will find everything. If I don't, I am not sure I can make this mod.. Is it the only way ? I did find the pin on the KBC that is...

Hi, I do have a more precise multimeter now. I rechecked impedances of the BIOS chip, between pin 4 and the others. Here are the results on the display: 1 : 5 Mega ohms 2 : 5 Mega ohms 3 : 68 kOhms 5 : 5 Mega ohms 6: 5 Mega ohms 7 : 16 kOhms 8 : 14 kOhms (Datasheet) ...

Ok, I will get a new one at the beginning of next week normally, and redo the tests. I found this chip, which should be what we are looking for. But there are no pins reachable from what I can see. But I can see the lines between the chip and the resistances around, so maybe I can check voltage...

Before pressing : VIN_SEN (47) : 0V VDD33 (44) : 2V VDD18 (26) : 1V EN (37) : 0v PE (36) : 2V SLP_S0# (35) : 2V After pressing, the values remain the same. The pins are very clothes to each other, so especially for the 36 and 35, i might have touch both of them at once, but I was very carefull...

I made a GDrive link, to keep the pictures in High quality. I made 1 image focussed on the chip you asked, and 4 others showing all parts of the motherboard. Hope it will helps ! https://drive.google.com/open?id=1nHiXbjGt1KWSCpkHkn958fZSk6ldIs3Z Tell me if there is any problem with the link
