      Lenovo B590 20208 Bios Problem
      by bbusterscruggs
      Hello, I wanted to update my laptop's BIOS from h1et40ww to h9et92ww. The website says I need to install h9et75ww first, so I tried installing that version first, but the installation failed and when I press the power button, the laptop momentarily turns on and off (the power light immediately flashes). I tried the crisis files with Fn+R but they didn't work (it works for about 30 seconds with Fn+R but nothing displays on the screen). How can I get a BIOS update file that I can use with Fn+R? Maybe I'm naming the files I put on the USB drive incorrectly. The ones I've tried are bios.bin, bios.cap,...

      Summary of BIOS Whitelist Removal Problem


      Problem:
      I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
      Initial Findings:

      For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification.

      Lenovo E15 Gen 2 GE4B0 GE5B0 NM-D011 Rev 1.0 sometimes not opening problem
      by s_specialist
      Recently, I have started to encounter a problem with Lenovo E15 Gen 2 models not opening. When you try to open the device, it gives a warning sound and does not display an image, when you apply light pressure on the keyboard, the image appears and works for a while, when you turn it off and on, the same thing happens again. Bios was tried, RAM slots were cleaned and soldered to the legs, the problem still persists. There seems to be a problem with the onboard processors, but since Lenovos glue the processor firmly from the sides, the paths are very damaged when removing it. Has anyone encountered...
