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?...

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.

Vertical Lines on Half of LCD Display

by rfxcasey

I have an Siemens HMI with vertical lines on half of the screen. These lines aren't scrambled garbage but rather very regular in pattern and color. I have replaced the LCD with a new one and still the problem persists. I'm wondering if this isn't indicative of a bad video process chip or video memory? Any help would be appreciated. The cable appears to be OK but one pin on the header is unpopulated, though there isn't any loose wire to suggest one broke off or popped out of the connector. In the picture below where the connector is busted out of the side, I did that with my small screw driver...

TCL 43S405 No image

by m4a2t0t

Backlights do come one but I see no image on screen. If I remove the LEFT side TCON cable I get an image on the left side of the screen and I can see the menus working (right side appears black/dark grey with a few large lighter grey bars), removing the right side cable and I get a black screen. It appeared there was a damaged IC on the TCON so I replaced it but there was no change. Is the panel bad?...

by hotgly

After upgrading the factory 128Gb SSD to a 512Gb WD_Black SN770M, this surface pro lost touch on screen, no touch in windows or in UEFI.
The Human Interface Devices did find touch and stylus but it shows Disabled in windows device manager.

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...
