    8th gen 13" HP Spectre X360 - Is there a MODS like utility to determine which chip is faulty?
    by AJ847.63e
    Hi All,

    We've got a 8th gen 13" Spectre X360 which seems to have faulty onboard memory. Windows was bluescreening with Memory_management errors. Running HPs built in memory test brings up memory errors, but it does not tell you which chip. Is there a MODS like program so you can determine this? Memory is on board unfortunately and don't really want to go order 8 chips and replace all 8 if I don't have to.

    Lastly do you have to use the exact same chips, or can you use chips with the same specs but from other manufactures?

    Thanks for your assistance....

    Replacing a Current Sense Resistor
    by Darren Hibbert
    Hi.

    Quick question.

    I have a laptop that is completely dead. I opened it up and it looks like the current sense resistor is blown. However, because it's blown, the value printed on the top has disintegrated and there is no schematic available for this particular laptop (Dynabook Portege) so I'm not sure what to replace it with.

    Marshall Stanmore II - chip flash
    by jingleslacks
    Hey Friends!

    I have both a live and demo unit. Demo unit firmware disables Bluetooth, power toggle, and other settings. Resets via button combos will not work on these. Reaching out to Marshall is not an option either.

    I copied my live CMOS chip and flashed it to the demo unit, but that didn't fix it (MX25U3235F) This has worked for other devices in the past. I'm not a chip expert, but I'm assuming the firmware is stored in another chip.

    If anyone has any experience or ideas, let's hear them!

    There is 2 sia ics and in 1 section where u see dots on the coils i have 2.2ohm there and there is no voltage on them at all.

    Also i read in other topić how psu works on these tvs and when u pług it in there is constant 40w draw from wall. When I unplug display from tcon it drops 10w when I unplug tcon it drops another 10w (unplug done w/o power ).

    I'm mostly sure its main board cpu cause no sygnał to turn on 24 volt for panel and its constant draw.

    For now I'm just curios about these w coils . Could not find any datasheet for ic thats the lines go...

    by HTR-Informatique
    Hello,
    I have a Dell Latitude 5420 stuck on the Dell Security Manager message on startup, I can't do anything.
    Here is my BIOS and what I assume is ME (32MB for BIOS and 1MB for ME).
    If someone could remove my BIOS password for me so I can reflash it afterwards.
    It's an 8FC8.

    Caps and num lock blink 4 times
    by AdrenalinTL
    I am sitting with a very similar issue.

    Basically, had a probook that worked, gave it to someone, they returned it DOA. what the heck happened, I have no idea.

    Caps and num lock blink 4 times, as per HP, thats a board failure. I am very new to this, so perhaps I should be posting a new thread?

    Anyway, I resoldered the bios chip on after trying EVERYTHING else including reseating ram, cpu etc.

    Multimeter shows 19.5V on power, so I presume thats correct. Fan spins, no display. No post. Bios chip looks good from what I can tell just not sure how...

    Bios password removal request for Zbook 14u G6

    Hello there, thank you to whoever will be kind to look into this.
    I need a bios password removal for a Zbook 14u G6, SN 5CG9516ZPT and not sure if this is the mobo identification you are after (hope so) M/B SPS:L65694-601

    I attach my 32,768 KB file which is the only one I managed to locate and extract for now, hoping it's the only one needed. I tried to read as much as possible on the forum and I have already
    downloaded the 6050A3022501-MB-A01sound fix final flash.bin file that, from what I gather, could be already what I need... but since I'm so crap at soldering I would...

    Macbook Pro 2020 Touch Bar A2289 Ambient sensor and camera not working
    by kuba2102
    Hi everyone. I have this laptop after water damage. The main board wasn't really affected apart from a slight residue but components seem unharmed, but trackpad was very corroded and had to replace a few components. The problem is that the ALS ambient light sensor isn't working as well as camera. Sometimes even my screen image goes blank with backlight on and I have to close the lid and reopen it. I believe there is some issue with communication as

    Hi,

    Trying to work out if this is TFT problem or TCon issue.
    The TV powers up but the top half of the screen, from the right it is OK, but as you look across to the left halfway across it starts get duller and duller until it is very dark on the lefthand side, currently I trying to clean the remote as it seems to have something film wise on the pads stopping it from registering buttons pressed.

    Also when changing the screen size of Windows PC display to say to a smaller pixel sizewindow, the original window displayin the top left stays/takes a few seconds to disappear?...
