    A1990 820-01041 5V .4A Troubleshoot
    by abajor
    I have the above mentioned MBP, quick scan with thermal camera revealed that only U3200 was heating up. I found that C3208, C3219 and C3205 were all reading ~6.8ohms to ground.
    so I swapped U3200.

    I connected the PSU again for a quick check on thermal it's drawing about the same amount of current but now I'm seeing only heat radiating from U7800 and the T2 chip from under the black shielding fabric, and the bottom of the board.
    It's hard to judge the actual temperature without removing the shielding.

    Does anybody have any insights?

    820-00165 Random green light on charger
    by ahoonid
    Hey everyone,

    I have a MacBook Air 2017 with a weird problem. The MacBook was totally dead at first and the culprit was the C7430 capacitor which was obvious upon initial inspection as it had a fracture on its surface.

    The F7140 fuse was also blown so I changed them both. L7130 due to corrosion was also replaced. Now everything works again. Laptops turns on and everything seems reliable at this point.

    The only issue that I'm afraid might bite me in the ass later is the magsafe light as it randomly changes light from orange to green while charging. Other times...

    by pietrek1133
    Hi, Lately I bought an Razer Blade 14 laptop, from 2016 (RZ09-01652). Unfortunetaly, someone probably practiced soldering on it and there are few lost components: L1, U5 and PU7. Model of motherboard is Betty_R4 MB V3.0 20151216. Could someone check the names of the components for me? Thanks in advance.

    Can I fit a UE49MU6470 Diffuser into a UE49NU7100K?
    by fuus
    Evening all,

    Long time no post!

    I have a UE49NU7100K here with the classic melted diffuser and damaged backlight from getting too hot. Locally there is a UE49MU6470 available which I could pick up to replace the melted diffuser. Would this work or am I missing something? They look like the same style of backlight.

    If this sounds good, where is the best place to buy a new backlight? Will I regret buying from Aliexpress?

    Thanks in advance for any help

    TRIAC circuit
    by прямо
    Anyone is familiar with a TRIAC circuit?

    I came across this schematic, and I built it, but I can't seem to figure it out why I'm getting a low AC voltage output at the TRIAC terminals.

    With 230V AC hot side at the TRIAC MT2, I measured 60V AC between MT1 and neutral side when the comparator output LED indicator is on, and 20V AC when it is off.

    Same result if 230V AC hot side is at MT1, and I measured between MT2 and neutral side.

    My heating element doesn't work with 60V AC. It's not even getting hot and the thermocouple amplifier output is a...

    INSPIRON 5570 bios maddeningly slow
    by Txus3232
    hi guys, i have dell inspiron 5570 with a maddeningly slow bios.
    specs are: service tag 6MSTDP2 CAL50/DAL10 LA-F115P REV: 1.0(A00) CORE I5 with radeon graphics
    When I turn on the computer it takes approximately 5 to 10 minutes to boot Windows, sometimes up to 15 minutes.
    That slowness is visible even within the bios menu. It seems as if the clock frequency has been reduced drastically
    I already tried some dumps that are in this magnificent forum, I also followed the tutorial by mr [B][URL="https://www.badcaps.net/member/237374-smdflea"]SMDFlea[/URL][/B]​ to...
