    Modify BIOS to non-uefi
    by hexdy
    Hello, I wanted to know if it is possible to modify a BIOS file to accept a legacy disk when it does not have the capability, I had this problem on a Optiplex 3060 that were donated to my job where we use non-uefi linux distros, we cannot use uefi since is a "big machine" with this systems beign the center of all of it, we can't change the distro now, maybe make some changes, but if I can modify the BIOS it would be awesome.

    Samsung LED UHD TV - Bad Main Board or Bad T-Con Board? Pictures inside
    by E--Man
    Hi All,

    Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.

    Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.

    The lines are green in color when the tv is in "Game Mode" and...

    Samsung QE50Q60TAU - Horizontal screen lines
    by Runlinc
    Hi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.

    I am left with a good image apart from the black horizontal lines that I cannot get rid of.

    I cannot find anything on the buffer boards that has shorted.

    Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.

    Many thanks for your assistance

    Dead LA-H323P (no light) - HP 15-DW
    by Patan
    Need help here...
    I'm new on the forum and I'm not professional in electronics so i ask sorry in advance for eventual errors...
    As title says, i have a LA-H323P dead.

    Now, little background.
    The computer was working fine, just seems that the cable of screen was dying because it had the classic color problem, sometimes green, sometimes violet, sometimes perfect, but anyway working.
    When i opened it the battery was so fat that was seriously near to explode.​
    So i removed the battery... and turned on the notebook... that was, again, working perfectly fine....

    Yamaha stagepass 500
    by gbaicu51
    Hi all,
    Looking for advice please, regarding those 2( film capacitor?? - honestly not too confident if are film capacitors). Short version of story : I bought a stagepass 500 active speakers, and found those components nearly blown. I know they are 1= L 125. Any advice where I could find them to buy, and also what else could lead to this fault?( I have a multimeter and soldering iron and I can get fixed if someone could give me some instructions)
    Thanks all

    Battery not charging in ASUS G532LWS Motherboard -> BQ24780S
    by cope
    Hi everyone,

    I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.

    Some history:

    Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.

    As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)

    Now, with a new battery the system will start up and run off...

    Lenovo Ideapad 320-15ikb: Comes on and goes off
    by Nagyesz
    Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
    After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.

    (!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.

    Any insights on what might be causing this?...

    A1706 Won't Turn on 20V/0.3A draw
    by fharris1977
    I have a MacBook Pro Touchbar A1706 that won't turn on. With the board removed I'm getting 19.62V and an average amp draw of 0.300A. When I first plug in my ampmeter it goes from 5V to 19.62V after a second or 2 and the amp draw starts at about 0.688A and up to about 0.790A and then it gradually goes down to about 0.155A and works it way up to around 0.330A and then it fluctuates in the range of about 0.200A-0.350A. The voltage stays at 19.62V. Can someone with any experience with this issue help me out. I checked all the main power rails and they were present. Anyone know it would be greatly...
