    Asus X705UV bios
    by MDSI
    Hello.

    I have an Asus X705UV which no longer starts since the last Windows update. I suspect Windows Update of having tried to update the bios and having corrupted it, because currently, I have the charging indicator when I plug in the charger and I have the power indicator when I press the on/off button but nothing more, not even a fan running.
    Could someone check this bios and if it is broken, repair it?

    Sorry in advance, google translate is useful but not perfect. 😂

    Thank you in advance !​ 🙏...

    Troubleshooting Asus Tuf Gaming A15 FA506QM 33v & 5v rails
    by orgamisho
    Hello!

    I am still learning on laptop repairs and I am currently working on the above mentioned device.
    Currently the laptop is dead (no power on). The device takes 2-3 mA when 20v are injected onto the charging plug.
    Main power rail is present (20v), but no other power rail is present, including the 3v and 5v. I noticed that when no power is connected the 3v and 5v coils have large (normal) resistence to ground, but when I plug the power, both are being shorted to ground.
    I wonder is that an expected behavior or there is an outer protection activated.

    Yamaha delay D1500, zener diode broken with no marking
    by debidoobs
    Hello,

    im actually trying to save a d1500 delay from yamaha. I found the service manual but schematic is missing and BOM list is a bit unclear as components listed have no reference linked to the pcbs... In my case, one zener diode was broken (114 code on the pcb in attached file) and couldn't be repaired : it was a zener type package. In the BOM list i found 3 reference on this board : 1S555 (can be replaced by 1N4148), RD4.7EB2 (approx 5v rectifier), RD7.5EB3 (approx 7v rectifier)...

    Actually the cathode goes to VCC of sram M5M5118P, without this diode missing, i have...

    Evaluating Mechanical Hard Drives SMART Data in Linux (Ubuntu) Using the Disks Utility.
    by abajor
    I've gotten into the habit of Looking at peoples Mechanical Hard drives with a Ubuntu thumb drive to boot their system.
    I understand the raw values are not really uniform between manufacturers, but I have noticed that high seek and read error raw values at the very least correlate to a drive that is going to have sub par access time, and extremely slow OS booting.
    The odd thing is I've often seen very high seek and read error rates on drives with fairly low on time.

    Does anybody have any other takes on evaluating smart data? I've used Crystal Disk Info, It seems to present...

    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?
