The main problem with the laptop is that the charge does not rise to 56%.
I found a bios from this forum and wrote it. This time the charge increased normally.
But I get a problem manufactured error. I added the original bios files. The battery was tested and it is fully charged in another machine....

Hello! Has anyone encountered problems on the Imac 2020 27 inches with a T2 chip? I had to replace 2 T2 chips on two iMacs, the first one was successfully replaced, tested and given to the client. The second iMac after replacing the T2 is flashed, the system is installed through the target mod, it boots into the system, you can hear me tapping on the keyboard, but the image does not display (and to an external monitor). I reballed the T2 chip, changed the processor, RAM, display. No positive result! My friend said that he had 2 such devices and on both of them, after replacing the T2 boards,...

Need help, I took out the motherboard, because nothing is spinning, no fan, no screen, no usb. I'm trying to fix it... I've watched several tutorials but I'm wondering how to start checking. This is my daughter-in-law's laptop, she said, if you can, great, if not, scrap it. So I'll take my chance. I ask for help before I pose an unresolved problem. Thank you very much for the advice. Oupss, I forget, when I push the start button del is lighted about 1 sec. and shut off. I can do this again and no change.

Hi,

Finally got time to fix this board up.
At first it didn't give any POST codes. Turns out it was an unsupported Celeron D cpu. After dropping in an Celery 2.6gHz the CPU came out of reset with clock signal, but still no post codes. For a while it did work when I applied pressure to the ADP3168 chip, but on next reboot the MOSFETs started to burn. Then I left it as is for months.

Now I came back prepared. Replaced the bad MOSFETs and the ADPxx18k drivers. Now I don't get any MOSFETs blowing up issues anymore. But sadly, the Vcore is missing. The whole VRM isn't...

Hello,
I'm having an issue with the Samsung 740n's phase control setting. When I use the automatic adjustment, it sets the value to around 54 (with a range of 0-100), and the picture looks clear and sharp. However, after some time—like after playing a game—the text starts to look blurry. When I auto-adjust again, it may increase the value to 80, and everything becomes sharp once more. Yet, after a while, whether it's a few hours or a day later, the same blurriness returns, and I have to adjust it again.

Hello, hopefully somebody is able to help me. I recently purchased this msi board (MS-7D76 VER.2.2) on ebay in hopes of repairing it. And now that it's arrived it's got slightly more damage than I anticipated. I am looking for the values of these broken off components, or just the boardview. Thanks in advance.

[Éric Noiseux]

I don't know if I'm in the right place, but I'll take a chance. I would like to know if it is possible to have the boardview for this type of controller. I have a light that shows errors on the selenoid power supply. I opened the controller, I saw nothing that would indicate anything was burning. I have no idea what values I should be looking for.
Anything will be greatly appreciated. THANKS.

Recently, the [B]Raccoon Flash Explorer[/B] programmer has appeared.

It allows you to flash BIOS chips from any device without installing programs and drivers, and also very quickly make small changes without a long rewrite of the entire memory to change a few bytes.

Very easy to use and intuitive, even a housewife can handle it.

You can use absolutely any system binary file editor (HxD, WinHex, etc…) on any operating system, the possibilities are not limited by the ugly built-in editor like other programmers.

It has full cross-platform support,...

Hello,
The unit is stuck in an intermittent on/off cycle. When I plug in the power cord, the green "On" light activates without any command, flashes for a few seconds, then turns off. The red standby light comes on for a few seconds before the cycle repeats. During this time, I cannot turn off the unit manually; it will shut off automatically after about five minutes, and there is no picture. Occasionally, with repeated attempts to power it on, I eventually get a picture and sound, which function properly. When it does work, I measure several voltages, and they appear to be normal....

I upgraded display from HD to UHD recently, and I think I did everything right, battery was disabled in BIOS, and removed, yet the screen has no backlight. Both the old and new display behave the same way. I checked the motherboard and I see the fv1 fuse, and a fv2 spot for a fuse, but it's missing. Does anyone have any information on whether fv2 is responsible for backlight, or why it's missing? There's a schematic posted somewhere on this forum, but I can't view it as I don't have the hardware right now, since the laptop screen is broken and I run Linux.

I thought the sporadic posting might be capacitor related. Upon inspection, non of the caps are bulged or leaking and they are all original. So, I pulled them ALL. While the ESR is OK, over half of them are [I][B]leaking current [/B][/I]between 1 and 2 mA. The biggest offenders are way out of spec, like a 1500uf / 6.3V measuring 2600uF and many of...
