  • Macbook A1398 bios/EFI password reset

    Hi guys,

    A1398 efi password.
    Emc2909
    Board : 820-00138-A

    I've attempted to delete the bios/efi password for a mabook Pro 15" that I bought from a fellow who sold me some programming books. It was in working condition but unable to be unlocked because he couldn't remember the passwords. Unfortunately, after flashing the BIOS with my attempt to remove the EFI password, all I get is fans spinning, black screen, seems like the EFI is not operational. Touch pad becomes active (haptic feedback) but external USB keyboard is not and only the power button on the...

  • MacBook Pro 15" 2010 820-2850 intermittent charging

    I would like to get some help on a 820-2850 logic board with intermittent charging problem. Sometimes the battery will charge all the way and sometimes magsafe would be cycling between green and orange.

    I have already tried replacing dc-in board, swapping good battery, swapping genuine 85w chargers. None of that helps..

    when it is not intermittent:
    PPVBAT_G3H_CHGR_R is 12.07v

    when it is intermittent:
    When the light is green, PPVBAT_G3H_CHGR_R is 12.99v
    when the light is orange, PPVBAT_G3H_CHGR_R is 11.62v

    data line on the battery...

  • Blaupunkt 236/2071-GB-3B-HKDUP-UK stays in standby

    I am currently attempting to repair this television.

    Currently the television stays in standby mode (red light on the television) even after attempting to switch it on via the remote control or controls on the television itself. I have opened the television up and there was a electrolytic capacitor that looked bad therefore replaced this however this has made no difference and the same issue still persists.

    I am now thinking that this could be a EPROM issue? If yes, i have not yet been able to locate a EPROM dump for this make and model of television, if anyone can help...

    started a topic Dell 5410 greyed out BT

    Dell 5410 greyed out BT

    Well I've learned something new today. Of all the Dell laptops I've come across I have never seen bluetooth greyed out, and only to learn this is during the build from Dell factory. I've tried to pull the original BIOS and fix with another dell with the same issue on the forums, however the original was not recovered from the forum upgrade so I cannot do a comparison to attempt the fix on my own.

    If someone could help me out with this unit and I'll try the next one as so far I have 2 on my desk with this issue. Thanks in advance!

  • A2338 820-02020 5v 0.04A PP3V8_AON low

    Hey mon, its me again (sorry) so after fixing my own Mac I’m back to try and fix another one.

    I changed a CD3217 on this one. And it started bootlooping a few hours after the fix.

    5v, 0.20-0.30A for the first few seconds then drops to 0.00-0.05A.

    PPBUS_AON is 12v.
    PP5V_S2 is present.
    PP1V25_S2 is present.
    PP3V3_S2 is present.
    PP3V8_AON is 3.8v, but its diode mode was abnormally low (.150v instead .350v)
    And to make it even worse I accidentally touched PPBUS and 3V8 with my meter and the resistance is now 100 ohms (don’t...

  • AlienWare area 51m R1 noPOST

    Hi guys,
    I'm new to "all of this" but i'm very eager to learn.
    Here is the situation, I just bought an second hand alienware whose description was roughly this:

    "don't boot after a bios downgrade, 2 red and 1 blue code".

    I thought as a complete noob that it was a good opportunity to start learning 😁, i think that i will learn a lot before it work again😂.
    I searched for the service tag in this forum, maybe by chance i would have some info...
    And here it is :
