    replied to Dell Inspirion 15-5567 LA-D801P - power problem
    in Troubleshooting Laptops, Tablets, and Mobile Devices
    Please look at the picture.

    I have 3 Ohms on the bottom pad. I have a boardview from LA-B802P (similar to my board). The bottom pad is connected to the CPU but if I check the resistance with the RC137 resistor then I have 1.13 kOhm. On the other resistors next to it it is also high. The R137 resistor itself has 1.13 kOhm. It's possible that these values ​​are too small for this processor anyway. The top pad is 30 kOhm.

    PL500: 30 kOhm
    PL100 still has 0,8 Ohm but it connects to the PU100 system. Pin 6, 19, 20. I'll check if that's the problem here.​...

    ASUS ROG GR8ii - need bios or fix

    Hello!
    I have an Asus ROG GR8II computer with an I7-7700 processor and a GTX1060 3GB graphics card.
    The computer starts up but there is no image. I did some research on the Internet and it turns out that it may be a problem with the BIOS. I am looking for a functional BIOS image or if anyone is able to repair the original, I would greatly appreciate it. Thank you!​...

    I received an X270 laptop whose owner incorrectly updated the BIOS. It looks like the bios is definitely corrupted. Can anyone help me and is it possible to rebuild this bios? Is it better to upload another one?

    Lenovo T580 - LCD Panel problem - error 0288

    Good morning,
    I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....

    I confirm. I replaced mosffets q39 and q40. When they are gone, the board works, but when I put new ones in, the effect is unfortunately the same. My processor is damaged.

    Hi.

    Re: HP Elitebook 850 G1 Bios Unlock



    This is imposible. The chip 2 mb and 16 mb bios was in half (i don't know) cleaned/broken. Looks like someone has damaged the bios or interrupted its update.

    I need any bios with support both graphic card. In the future I will change the motherboard serial numbers if I have the appropriate bios...

    Re: HP Elitebook 850 G1 Bios Unlock

    Hi

    I bought hp 850 G1 in an unknown condition. I checked this model and the problem was a damaged bios, so I bought SOP8 programmer. In next step I desoldered two chips. One is 16 mb and second 2 mb. I cleaned both chips. My motherboard model number is 6050A2559101-MB-A03. I find in internet bios for my motherboard but the bios was to the HP 840 (this is the same motherboard model). So I flashed both chips and solder to the motherboard. Laptop turn on but I was glad too quickly.

    In this moment i have two problems:...
