Did I just bricked my laptop? I reinstalled ubuntu but after rebooting it would fall into bootloop with a "reset system" message. In the tutorial I read that sometimes it helps to enable secure boot, well I did that but now I can't get into BIOS/UEFI at all. Laptop: lenovo thinkpad x1 carbon 3rd Anyone could help somehow?

Thank you all very much for your replies and help. Removing the disk and battery helped, the laptop turned on to UEFI settings. But does anyone have an idea how to solve this bootloop with Ubuntu now? Fresh system and partitioning through the default settings of the ubuntu 25.04 installer. When I turn it on this message appears for a few seconds and then the computer resets. One tutorial on the internet told me to turn on secure boot but as you can see from my first post it didn't do anything.

Solved. I found a boot-repair tool. Run it from live CD and it repaired my ubuntu installation. Thanks for answers and help!

  • Power off. Power on and keep pressing to get into bios
  • Turn off secure boot again
  • Exit and save values
  • Keep pressing to get into the boot menu
  • Try booting linux and take it from there

I tried it and it doesn't work. Also I tried to reset by emergency reset hole and it also doesn't work

You could try and remove the power supply, the batteries and the cmos battery. Then use the power-on button a few times (won't start but could help drain all components of residual charges.

Now put it all together again and hope for the best.

Are you meaning that you cannot power off?

I can but it doesn't help. When I turn it back on, the same message appears and I still can't do anything.

What's the exact model please? It may be possible to reset the CMOS if we can cut power to the main board completely; there's usually a coin-cell battery to keep a minor charge supplied to the volatile memory holding the current config, but the exact model number of the laptop will let us find the spec sheet so we know for sure.

This the photo from the back cover.

I looked up the TP00061B and selected 3rd gen, I found this: https://download.lenovo.com/pccbbs/mobiles_pdf/x1_carbon3_hmm_en_sp40g55065_01.pdf

Looks like there's a coin cell battery in there, so you can remove it to reset the CMOS. I'm not sure how relevant this video is to your exact model, but I'm sure you can figure it out using this as a base if you're comfortable working on computers generally: https://www.youtube.com/watch?v=secIrlXFy5k

Edit: Oh, I see you got it! Nice ๐Ÿ™Œ Happy computing!

In the tutorial I read that sometimes it helps to enable secure boot

Just as an FYI, normally you would enable or disable secure boot before installing an OS, not after the fact. Otherwise you usually end up breaking the boot process.

Normally you should be able to hit Enter and then follow prompts to get into the BIOS. Maybe hit ENTER then just keep hitting whatever key you were using to get into the BIOS prior (F2, DEL, etc.).

If none of that works try powering off, removing the hard drive, then power back on & see if that lets you get back into the BIOS.

If that still doesn't work I suspect the laptop is still stuck in power on mode, maybe the internal battery is keeping it on. Try to see if you can actually power it off for real e.g. hold the power button down for x seconds until you see lights go out. Try to keep an eye on how the laptop behaves when powered on vs lower power mode vs full power off.

Photo moments before the tragedy. I changed these settings.

I can't get into BIOS setting, it's stuck on the message from my first post.

Press Enter.

I see from your photo that it's a Lenovo - pressing Enter to interrupt normal startup will give you a menu which then lets you get into the BIOS.

If it doesn't go past the "press Enter" point you might need to remove the HDD (or whatever storage it has) and try again. Reconnect once you've changed the settings back.

Removing SSD and battery help. Thank you.
