    820-4924 bios

    https://drive.google.com/open?id=1LuI6iWyfVq9NMtGe9SSVmIvtgYjeCBT7 Don't touch serial number without correcting the CRC.

    A1466 820-3437-b not turning on

    I think you do not know how to use a multimeter. If you are measuring a resistor you measure across the resistor and on the Ohm scale. Caps you can never measure in circuit if you wanted to measure capacity. On diode mode you would never get 80.1u. I really do not understand what you are trying...

    820-00244 no power anywhere

    If U6100 is chipped you are screwed. If it really is dead there is no way to get the SSD to work anymore as there is code in U6100 that is unique to the SSD on the board. Post a picture of U6100 to asses damage. If you have an adapter see if you can read U6100 through J6100.

    820-2610 LFXP2-8E5MGC replacable with LFXP2-8E5MGCAD2?

    No idea, but these have firmware. Normally they do not die, just need reflow/reball. You can probably get away with using one from a 15" 2009 board.

    Trackpad has corrosion. Either clean or replace.

    A1466 820-3437-b not turning on

    What is a "u" symble? Resistance is measured in Ohm, KOhm, MOhm etc.

    Just remove R6805 and be happy.

    820-3476 Green/Orange light, Not turning on, Corrosion around U7501

    I would first confirm pin 23 actually has 12.6V on it before doing anything else.

    A1466 820-3437-b not turning on

    12.50 what? K M Ohm? Are you measuring with power removed? The usual culprits are R6110-28 and traces between them

    LCDs have standard pinout. It is either a 30 pin eDP or 40 pin LVDS. Google is your friend.

    A1466 820-3437-b not turning on

    The usual suspects should be inspected now. Corrosion on U1900/U1950 pin 8/J6100/U6100 and traces and resistors going to U6100.

    820-3437-B not turning when battery is pluged

    PPBUS voltage? Inspected IO board and flat cable for corrosion? Orange light must always be present on charger even without battery.

    820-3476 Board gets warm, no fan spinning, not booting up, Corrosion around U7501

    This does not sound good! PPBUS is low and CPU is getting warm. I suspect PPBUS is shorted to some secondary rail. Probably RIP.

    820-3476 Green/Orange light, Not turning on, Corrosion around U7501

    Double check if pin 23 is actually making contact with the chip as it usually is destroyed. SMC_PM_G2_EN present?

    820-00165 not booting liquid damage (T3582)

    Can you get to the boot menu by holding down option key? Could be possible EFI lock, PRAM reset done?

    lenovo no backlight

    Only 3 signals to the LCD. 19V, enable and PWM. Look up the pinout for the LCD and check voltages. Did this happen after an LCD swap with the battery installed?

    820-3662 Video Issue

    I ordered from 4 sellers and all was garbage. I have 6708 on the way and I have no idea what the difference is as there is no datasheet for the 6808 as it is an Apple only part number.

    820-00928-A No display on internal (works external)

    U9800 certainly has firmware, get a donor board.
