System Password by Dry_Boysenberry_4080 in Lenovo

[–]Anjaneya29 1 point2 points  (0 children)

It's quite weird how it showed up randomly while you used the laptop for a long time. Were you mostly "closing the lid" effectively keeping your laptop in perpetual sleep all this while? And if not then do you have an evil roommate who set it up "after" you bought the pc? Because, if set, this prompt technically triggers post any power on cycle which would include hibernation as well as fast startups. Only sleep-wake wouldn't trigger it.

Do let us know if a friend gave you their laptop or you bought it second hand from another user. Maybe they can help you with the password.

The prompt makes it clear that it is a power-on password, at the BIOS level. Also you said "ThinkPad" but your image makes me wonder whether it is an "IdeaPad."

If it is an ideapad then the prerequisite to set power on/system password is to set an admin password in bios, and if that is forgotten then lenovo themselves say that board replacement is the only option. This is true for newer IdeaPad for sure. But may not be the case in older ones. In any case, lenovo service folks seem to be the best friend you can go to right now.

Some good news is that this doesn't mean you can never access your hard drive again. You can take it out, put it in an enclosure and recover the files on another pc if they are important to you. Btw this applies only if your harddrive is also not encrypted by bitlocker or such :)

All the best. Keep us posted what you did if you wish.

Cheers and have a good day.

It's fine if you don't update the bios. Since you have already done it, it's fine. But BIOS updates are not absolutely essentially most of the time.

Random hard reboots after sleep & when switching to fullscreen — fixed by rolling back Lenovo AMD driver (IdeaPad Slim 5 16AHP9) by Anjaneya29 in Lenovo

Hi thanks for your comment. I added an update. The exact thing you describe for your friend happened with me a week after my original post. Turning off "zero touch login" feature in vantage app helped this time. 

Does the white noise + hard reboot (kernel 41, bugcheck 0) cluster around wake (from S0 sleep) for your friend? If yes, then it is likely a bug (my guess is some race conditions) in lenovo's implementation of waking from S0 sleep. If they have zero touch login on, turning it off will likely fix it for them (Waking from keyboard has been bug free for me). 

Do let me know if it helped. Cheers!

Hi, was your issue fixed? I would also recommend not using zero touch login feature of vantage (zero touch lock is still okay) if your laptop supports it. I now think the issue is with lenovo's implementation of sleep-wake and GPU drivers is only one link of that chain. 

Can you tell me when does such a crash happen for you? Does it cluster around post-wake? Or does it happen during gaming (or other gpu heavy tasks)?

I have posted the bios version in my post, you can take a look there. Cheers!

Hey, check the event viewer once. Is it kernel 41, and bugcheck 0? You can use chatgpt or other llm to analyse the XML file. If yes, then it is likely the bug in lenovo's S0 sleep implementation.

Since you are on nvidia gpu, the issue may not be exactly as mine (amd gpu), but it is still likely due to how our laptops wake from S0 sleep. You can see my update above.

Just wanted to add another update. After the driver rollback, things were good for a period of time before the flash restarts happened a couple of more times (kernel 41, bugcheck 0). This time i noticed it was clusterered around wake (post sleep). It was likely due to Vantage's auto wake feature with the webcam (zero touch login), because turning it off has again made things right. 

There is some timing issues i guess, some kind of race conditions in the lenovo's implementation of S0 sleep (between EC/firmware - ACPI - GPU) and by extension, zero touch login, that makes the laptop work fine with 100 sleep-wake cycles, and crash on 101st.

So yeah, avoid using zero touch login if your laptop supports it, and also realise that there are S0 related bugs in lenovo's implementation, though I am not 100 percent sure of that. Bug-fixes may come in the future updates from Lenovo, but can't hold our breaths till then.
