    Lenovo thinkbook 14-ill BIOS
    by Chapita
    Hi team,

    I bought a lenovo thinkbook 14-iil with a core i 5 processor, Radeon graphics chip, board number: DALVACMB8DO - REV D from an auction. It does not have a bios chip and my guess is that someone disoldered it, so I am planning to buy a new replacement bios chip but I do not know how to reprogram the chip, can someone assist please​

    Help Identifying this chip - 324
    by cook
    See the attached drawing of the chip I am trying to identify. I think the last character (the 'H') may actually be the manufacturer logo, but I am not sure.

    This chip is part of a hand held device that detects metal. Its called a pinpointer, and is used in the metal detecting community. The chip is located on the main power rail which is from a 9 volt battery, noted in the drawing.

    I tried many searches to find the part, but did not see anything that looked close. But then I have very little experience doing this and I could have easily missed something obviou...

    faulty loudspeaker amplifier-no sound output
    by Cornboats
    I've several amplifiers of different sizes which are faulty. I haven't fixed them because I haven't a clue. This is the smallest culprit. 240v in (UK) and 12v dc to the board. Small neon lights when power button is on. Different dc voltages across all of the capacitors. Where do I go from here?

    Samsung flicker - BN44-00932T board or else?
    by fixit007
    I picked up this TV that the prior owner said - just died.

    Tested the fuse - burnt. A dead capacitor is visible too on the hot side (CP801). Got the replacement power board (cheaply - used). Replaced the board - the TV turned ON!

    Now, about a month later (yesterday) I noticed the left side of the screen was flickering from time to time. That was already happening with the antenna input, not through HDMI.

    Also, some glitchiness with a Fire stick on HDMI3 - I hit an app with quick dark screen in stick, the TV goes - no input. Then I had to choose the stick...

    by Franito
    I have a rx6600xt in the same situation.
    The first pin of npc81022 ( powerok) has 0 v, and doesn't activate the other and gates.

    I'm not sure if I can bridge with powergoods.

    I don't have the schematic for this gpu sapphire, and i dont know why I don't have power ok if all coils are marking good voltages.

    ¿Maybe gpu core dead?
    I see in a msi schematic powergood and powerok are bridged wwith a resistance, but in my gpu this place is empty....

    HP Elitebook 2540p - WP884AW#ABU - won't start!
    by smaniak
    The laptop won't start. When plug power supply, on 19V in gives me 0,14A, without turning on the laptop.
    I check it with thermal camera, and there is one resistor that is very hot, I change the resistor with new on but the result is the same.
    In the attachment there is schematic of the resistor area, and schematic of the laptop.
    I can't understand, why this resistor is getting so hot....

    Main rail / charging circuit issues on Bucky/BenSolo 17859-1 board from Dell Vostro 5581
    by benwaterson
    Hi All

    Been a while since I have been here, and a bit rusty.

    I have the above laptop motherboard that was working and now the charging circuit is faulty.

    Have 19v in fine until it hits PU4403 - not shorts I can see and thermal cam reveals nothing.

    I have swapped out the ISL9538 and also the two mosfets (PU4403 and PU4405). Have 2.8v at the power switch, which pulls low when pressed - charging light comes on and goes straight off

    Below are measurements (pin names are per the datasheet for the ISL95338 (couldn't find one for ISL9538,...

    Lenovo t470 Bad pathway
    by lofton
    Hello, I was updating the bios on my t470 20jn pf1q6dx5 using the soic8 clip that came with the Ch341A on the bios and pressed the clip too far back when i was taking it out and it knocked off what look like little capacitors, can this be repaired or bypassed with solder or a wire or what was originally on there, they are extremely small. I have attached two pictures, one with the capacitors on and one with them off. It took me weeks to figure out why the board wouldn't power on. I thought I had broke the bios. THe machine turns on for a second then turns off.
