    Dell Latitude 7290 enable touchscreen entry in BIOS?

    For those that have worked through the 7290 BIOS in the past, do you happen to know if there is a switch in it to enable a touchscreen entry in the BIOS setup?

    The 7290, 7390, and 7490 all use the same BIOS, and the 7390 has an FHD touchscreen as one of its' options. It turns out it can be installed in a 7290 BUT since the BIOS doesn't have the entry to turn it on, it just becomes an FHD upgrade to the 7290.

    I was hoping if any of you that had worked on the BIOS in the past would know if either the touchscreen settings could be turned on in the 7290, or the BIOS could be convinced that a 7290 is a 7390. Since they share the same motherboard, the screen works on both, and the 7290 DOES have the touchscreen socket for the cable. I have a 7390 touchscreen installed on a 7290, would LOVE to get the touchscreen working.

    There might be a differet OEM configuration in the ME firmware settings, havn`t checked. It`s possible that it could also be set with resistor straps on the motherboard, depending on the motherboard revision, dell D/PN

      ASUS TP500LA BIOS request/repair/merge?
      by jbonavita
      Hi, my laptop wont boot at all
      With original bios no POST, only LED lights
      With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
      Some issues
      A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
      B- If updated from 500LN version 203 to 300, the battery stops being recognized

      Things I tried

      1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

      [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
      by zenius
      Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

      Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

      Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
      by Wahaz
      Hello,

      I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
      So I thought it was a Bios problem.
      I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

      HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
      by Bloodhoundje
      Hi everyone,

      I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

      I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

      After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

      I have desoldered the bios chip (GigaDevice...
