Re: P51s external monitor random shut off

Very good point. I guess if I submit the laptop before the warranty and they are unable to fix the issue, they may have to supply a new laptop. I'm guessing they are very well aware of the issue and are choosing to ignore it. The least they could do is offer docking stations as a viable workaround. That's cheaper than full replacements.

I'd be VERY curious if that fix's it. If so I'll send mine in. I'd hate to send it in and still have the same problem back. Keep us all posted.

Will do. I won't be sending it in until mid-September. It's 1-days shipping each direction and 5-7 business days for the fix. I can't be without my laptop that long before then. If that takes you outside your warranty window, I recommend sending yours in. You can literally call on the day before your warranty ends and have them send you a shipping box and label. That will get you 'logged in' under the warranty. The box / label are good for 30 days.

Btw, I really do like the P51s especially when I'm traveling. I wish there was a quad chip option at the time but otherwise (HDMI issue aside) it's a great solution.

I see there is a new BIOS update as of a couple dates ago, did that help with this issue at all?

Before and after the latest BIOS update I did in Jul 30, I've found something interesting..

 

In the passed couple months I have been using my USB-C hub for all my USB connections, AND the HDMI; as a single connection like a dock.. This has eliminated the screen shut off issue..

 

For the passed week I tried an experiment, to retain use of the USB-C hub, but connect the HDMI direct through the HDMI port (instead of via USB-C).. NO ISSUES, before and after my Jul 30 BIOS update..

 

So I don't know if the ultimate determinant in solving the issue (for me) is to have the USB-C port occupied.. Anyway, now that I'm used to just plugging in a single USB-C port for all my connections besides power, I'm not so P.O.d any more about this silly HDMI port blanking out issue..

@ventureca WAIT WAIT, so you're saying plugging anything into the USB-C port, AND ALSO using the HDMI plug (for the video connection) will solve the issue ?

 


No anything USB-C cable will work. I tried plugging a normal USB-C cable that comes with my Samsung Galaxy S9. It didn't do the trick.  However,  plugging USB-C To VGA adapter that comes with my P51S (as picture 2) will prevent the blinking of the external monitor that connects through the HDMI cable.

@Ventureca

 

Then our commonality is the USB-C periphepral we plug in (to solve the HDMI blanking issue) has DISPLAY format conversion built into it.. MAKES SENSE.. So somehow we're using the USB-C port display format conversion to fool the display not to conk out.. LMAO what kind of convoluted programming gets built needing a convoluted solution like that... But like I said, I've learned to like my USB-C as an all-in-one single connection for everything besides power..

Re: P51s external monitor random shut off

With every BIOS update and every major Microsoft Windows 10 update I had been gleefully optimistic that somehow the problem would be magically solved. After over 15 months, that optimism seems to be wearing off. After this latest BIOS and Windows 10 update, I attached my dual monitor setup, one to USB-C and the other to the HDMI, and for about 4 hours it seemed to work without issues. I was very happy, until I started to see those ominous flickers of black screen on the monitor attached to the HDMI port. Then it began to flicker like crazy and I unplugged it for fear of damaging my nice new 27-inch monitor. So much for the optimism.

 

I have tested this with over 20 different monitors and projectors, different HDMI cables, even used HDMI cables with active signal conditioning, but the same problem always reappears. It is bad when it happens at my desk, but it can be very annoying and embarrassing when it happens while presenting on a large screen in a conference room or a conference hall in front of an audience. I apologize on behalf of Lenovo and ask if I could use someone else’s Dell or HP laptop to finish my presentation.

 

Thank you, Lenovo, for denying that this is a hardware issue or design defect and instead insisting that I should factory re-image my system again.

This is very frustrating. The issue itself isn't the frustrating part as we're used to imperfections (thanks Microsoft) with electronics. However, what is truly frustrating is the lack of response from Lenovo. As a result, i can't recommend their products nor will I look to them as a viable option for future expansion and/or replacement needs. They've really dropped the ball on this and it would be an easy fix. Send a docking station to all affected. That's cheaper than actually doing the repair. Or, offer a choice of docking station or repair.
