    Lenovo G555 Num Lock not working

    Today I got one Lenovo G555, which drinked too much coofee and energy drinks massive power shortages on board, corrosion, burned traces and so on, after repair few keys on keyboard were super sensitive, and Num lock didn't work.

    So I replaced keyboard with new one, but Num Lock not working again hmm...

    Checked KSI0-7 pins all ok 3.3V, checked feedback when pressing keys all ok.

    At first I thought SIO fault, then I tryed to reflash BIOS with older version, and hey "everything is working now"

          Lenovo T14 Gen 2 Type 20XK Model 20XK0069US Odd Charging Issues
          by coasterghost
          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. The System is out of warranty as it is but does have the option to have it extended.

          by hopkok
          Hi masters, I need your help.

          I am working on Lenovo Legion 16ITHg6
          Motherboard number NM-D721, no BV, no schematic but I am attaching very closes ones.

          INPORTANT: My motherboard version is with IT8258 IC, that is controlling keyboard and RGB LEDs.

          My problem is on UI142, +3VALW_AG is not stable, floating from 0V to 3,3V.
          AGKB_PWR_EN_N signal is floating too (that is why+3VALW_AG not stable).
          Power LED is not working as well, power button working well.
          UI26 ??? is there any firmware too? Powered by +3VALW_AG.

          Motherboard...

          Lenovo A485/T480 USB stops working when USB2.0 is plugged.
          by someonenotyou
          Hi.

          I have 2 Lenovo laptops (A485 and T480) with identical USB problem.
          When I plug in a USB 3.x device (USB storage), the USB ports are working normal.
          But as soon I plug in USB 2.0 device (mouse, USB storage), all the USB ports stop working. Even if I plug in USB 3.x device.

          The only way to get USB working again is disconnect battery and reset BIOS.

          Has anyone had anything similar?
          I have not yet tried another BIOS, but would that be the problem with USB?

          Thank you.
