2018-12-26 UPDATE: I heard back from Lenovo and it looks like as of a few days ago, Lenovo has resolved the issues shown in this video with a BIOS update. I will keep you posted if I run into any other major issues after I have done a thorough test.

– – – – – – –

So I got a handful of Lenovo Thinkpad P52 computers. The first thing I did was change the graphics mode from hybrid to discrete. This apparently renders the computer worthless and unable to get into BIOS again. I did some research and found out that this is a known problem and there is a BIOS fix for it.

So on my next computer I updated the BIOS and it did indeed fix that problem. I then found out later that enabling CSM support also renders the computer worthless and no longer able to boot or access BIOS.

I suspect that there may be other BIOS settings that can crash the computer but I didn’t have enough computers to find out.

This is a MAJOR problem and Lenovo needs to do a better job with quality assurance. These computers should have never shipped out.

I did call up Lenovo to talk to them about this. I was transferred a bunch of times and on the phone for over an hour. No one had an answer for this and as of now (2018-11-27) there is no current solution. Basically, if you want to enable CSM support on your P52 you are hosed (for now anyway).

  1. I wouldn't be buying the P52 with it's great specs for working, just to use the discrete graphics. If that was the case I would have bought a laptop at half the price.

  2. 1. I have Lenovo P52 as my main laptop, with Ubuntu 18.04 on it.
    2. All your have to do (instead of buzzing the tech-support and fixing the BIOS) is RTFM.
    3. Use USB stick with Ubuntu and READ about secure boot proper configuration – The installer will updates all during the proccess (BIOS, drivers, etc).
    p.s. All video from my channel, including playing PUBG under Ubuntu from Steam, has been recorder at Lenovo p52. It is an awesome laptop.

  3. When youre so retarded you do the exact thing that is a known issue that had a BIOS patch at the time this video was released. Autism.

  4. The bootlickers who disliked this video should have done their homework on the P52 firmware problems. They're acknowledges in the Lenovo forums so fantards need to STFU. They bricked MANY P52s. People who personally identify with any brand of anything should be gassed.

    Make sure your machine has the LATEST updates and KNOW what those are! DO NOT ASSUME any P52 you work on or use is has the latest updates. Check the Lenovo forums.

  5. I built my computer from scratch and I know better than to screw with settings that don't need to be changed. In addition, like another person said plug in a monitor or even better when you get it check to make sure drivers etc are up to date BEFORE you start changing things. Updates get made after the machines are produced and are not put on boxed machines. Why even bash this product when the average user will never do this and you should have known better to check for updates if you knew how to change bios settings?

  6. All – I purchased P52 a few months ago as replacement for a Yoga (still going strong after 5 months on the Appalachian Trail) -from day 1 the fingerprint sensor gave me issues…no biggie – I'll use the pin sign on. After the BSODs became a daily issue I called Tech Support and they got me sorted out (thank you TS) I called Tech Support again today after I noticed a crack had formed from the escape key to the outside edge big enough to put my fingernail in. I've had a hairline crack from the fingerprint sensor downward, but I didn't report that one because it's hairline. I was told I could send it in and they would probably bill me for fixing it.
    My concern is this – All the hype about military grade shell in the advertising and on several laptop review sites lead a person to think this laptop is actually quality built. I do travel with this laptop so the fractures could have happened during one of the frequent car rides, but really? Military grade? I don't think so!

  7. I would say that frequent crashing is a much bigger issue with the P52 than a few obscure settings in the BIOS. I analyze my memory dumps. I rarely have the same driver or application crash twice, yet my computer crashes. This leads me to suspect that my RAM is defective, or that the P52 has a power management problem that causes voltage drops when hungry components (like extra CPU cores or video card) turn on, causing memory errors (that show up as driver errors or kernel errors, or other types of software errors). Anyone here have a similar experience?

  8. For being unable to access Setup after enabling CSM, I suggest clearing the excessive boot options? The similar problem has been shown on older ThinkPad models like my ThinkPad X230, and removing unneeded boot options could help. Btw I hope a solution can be offered to you asap! 🙂

  9. Hi owner of P52, can I ask you that the bios setting Intel Virtualization (VT-d, VT-x) are enabled by default or enable these not make bricked? I very need these options, but i'm afraid changing any setting of this machine bios. You are would be life save if tell me that.

  10. Wonder if it's only specific nvidia gpus. My P52 has the quadro p3200, and with the BIOS that shipped didn't have an issue with the discrete mode on. I've updated the BIOS everytime a new one has been released with no issues. I hope a solution finds you!

  11. You don't need to change it to discrete graphics from the BIOS. You can change it from NVIDIA control panel.
    Second, it's not a bug. P52 ships with Windows 10 pro and CMS support is for Pre windows 8 and 10. If you want to install XP or Windows 7 you need that CMS support turn on.
    With windows 10 you don't need to and if you turn it on it suppose to not boot into windows 10 or 8. It's not a bug.
