                  Try a good power adapter, if adapters center pin is not connected then the behavior might be like that. If no good apapter at hand use 500kOhm resistor from id pin to gnd to simulate Lenovo smart adapter.

Aborting......I'm using another Linux Laptop with Zorin OS...to try and patch my Lenovo V15 G4 IRU with above specs....It originally had Windows 10/11 installed and converted to a dual boot Kali OS/Parrot OS system.

                          Lenovo X13-Yoga Gen 1: hibernation problems
                          by rumpumpel1
                          I have a Lenovo X13-Yoga Gen 1 that has problems with hibernation mode. When the laptop goes to hibernation mode - either via the start menu or after a time-out - after a short period of activity where the power-on LED flashes, the power consumption should go down to almost 0 and the LED should go out. Most of the time, however, the power consumption indicates further CPU activity and the power LED remains on, but there is no image. Sometimes the CPU activity stops after a few minutes, sometimes not at all. If the laptop enters this state, it can only be brought back to life by a long press on...

                          Make : Lenovo

                          System will not boot. I have tried the normal troubleshooting (external display, unplugged batter for 24hrs, holding the Novo button, tried to boot from usb using every typed of bootable media) i cannot get a display but keyboard backlight lights up but it's not responsive, fans spin and power button flashes but stops. After researching my symptoms, I am leaning towards a bad bios.

                          I have identified what looks to be 2 bios chips on my motherboard, both winbond...

                          Lenovo 11e problems (any sata hdds are not recognized, sleep battery drain)
                          by clabr
                          Need help to solve some problems with this laptop.

                          After working in bed with it one night and heating up too much (probably the cause of this problems) the sata HDD OS windows froze
                          After restart the original Sata HDD was not recognized anymore (but works fine in other laptops or PCs)

                          Tried connecting other good Sata 2.5 HDDs but not one is working in this laptop anymore (not the original nor others)

                          Before this had happened I observed some other problems:
                          When I tried replacing original mecanical HDD with a SSD HDD could not get them...
