    Asus GA401IV, power on, black screen

    I should mention pr8015 is only reading 3.4 ohm (6.4k should be on this), and pr8011 is only 154 ohm (23.2k should be on this). These are near the liquid effected area, so maybe I need to swap these out? I haven't found anything else this far off from specs in the schematic.

    Asus GA401IV, power on, black screen

    Just getting beck to this today.... The BV was a help. Checked if BIOS recovery worked, and it doesn't, so before trying a manual programming, I have been checking around the replaced chip. R0609 has 1.8v at pin 1 but not pin 2. Tests 4.7k Ohm. If this is PWR OK, shouldn't 1.8v go all the way...

    Asus GA401IV, power on, black screen

    Came in for repair and would cut all power when on switch was pressed. Found UP9505S had pin 16 damage from an old liquid spill.replaced the chip and fixed the pad. Powers on, keyboard lights up for a second. After about 10 seconds both fans max out. Hold power button will shut down after about...

    820-00923-A, known good tp/kb ribbon, not working.

    Body bent, not much but enough. Looking at R4513 first, and it was missing. Pretty sure this is now solved. Will verify by end of the day, just for a few things to do first.

    820-00923-A, known good tp/kb ribbon, not working.

    Board had slight bend, replaced pretty much everything, but the board never seems to work with built in tp/kb. Bought a macbook pro to test and the parts I got are good on the test system. the tp feedback still works, not that it matters with this design, but 3.3v and 5v are also present. Afraid...

    2018 13" MBP, to touchpad/keyboard when powered on. 820-00850

    Thought I turn off my subscription when I moved, and just getting a work flow going again, so it's good to still have this active. I try another part and see if that works. I don't have a working model on hand, but I'll update this when I get parts in. Thanks.

    2018 13" MBP, to touchpad/keyboard when powered on. 820-00850

    KB/TP don't work in the OS, and don't show as connected. SMC reset works. I need to turn my subscription back on to edit my typos... Thought it would prompt me to subscribe when I went to make a post. Rules must have changed here or my account is bugged.

    2018 13" MBP, to touchpad/keyboard when powered on. 820-00850

    Shift+Ctrl+Opton SMC reset works. Can't boot recover, no KB BL coming on. System was bent slightly, Replaced palmrest and screen. Same issue with replacement touchpad and keyboard. So I checked LB700, no power, looked at QB701, 11.8v on pin 8 with battery connected. Does this mean UB700 isn't...

    LA-B753P CPU error, 7 beeps. Alienware 17 R2

    the fix was to flash Super I/O. Connection was done through keyboard connection. Still used the TL866 II to flash it, then flashed a matching EC and BIOS. Everything is working again.

    Yes. Redid the flashing again. Back to 7 beeps. Also redid the EC chip solider after finding a loose leg.

    Same behavior, just a different color on the AW FX LEDs.

    LA-B753P CPU error, 7 beeps. Alienware 17 R2

    Got the chip needed from an AW Ranger. Used BIOS ver. A00. and programmed before placing it on the board and flashed EC to match. First boot was 5 beeps (normal after BIOS rest) power on to black screen, no beeps, reboots after about 1 minute and does the same, reboot, black screen. BIOS...

    LA-B753P CPU error, 7 beeps. Alienware 17 R2

    Schematic says it should be W25Q64FVSSIQ, my board has 25Q32FVSIQ, and when I go to read it, the software says "external short or IC revers or incorrect package". Second Winbond chip is EC. 25Q80DV, marked on the board as UE2, BIOS is UH4. There is flux left around and on both of these chips...

    LA-B753P CPU error, 7 beeps. Alienware 17 R2

    I was just able to get around to placing the order for a programmer. Found a US seller for the TL866li Plus. Never used a EEPROM tool before, but I doubt it will be hard to manage. ME region is in the same chip, right? These boards have two Winbond chips, Should i do a dump of both?
