Re: V510-15IKB Laptop Freeze

I'm afraid you're right. I always thought it was an hardware-related problem with the usb or some contact on the motherboard, something physical because it blocked more often when I moved the computer. The tried-and-tested settings so far had given me hope to have resolved (5 days without freeze) but today unfortunately it has already been freezed 3 times. So I can say that the "DRI" option "false" alone does not work. Let's see how it goes to others with "NoAccel" "true"

Re: V510-15IKB Laptop Freeze

 So far I have tested:

1) New Intel Drivers for Linux (Update Tool 2.0.5) - Not Works

2) In Xorg Configuration File Option "DRI" "false"  only - Not Works

3) In Xorg Configuration File Option "NoAccel" "true"  only - No System freeze but Graphical glitches

4) In Xorg Configuration File Option "NoAccel" "true" , Option "DRI" "false" both - No System Freeze and No Graphical glitches for 6-7 days until now but I'm not able to watch videos

 

Nenkoivanov so far how many days did your netbook runs without system freeze?

Re: V510-15IKB Laptop Freeze

I too am experiencing these issues. I though it might be the Kaby Lake hyperthreading bug, but even with the latest microcode installed in Linux, the freezes still occur. Turning TMP off didn't help.

What is to be done here, is there a chance of Lenovo giving a full refund?

Re: V510-15IKB Laptop Freeze

Hello all.

The same problem - notebook freeze...
I try test RAM with memtest86+, fist time - pass,  second time - reboot during the test. Probably, the OS doesn't matter
BIOS is 2WCN29WW (2017.07.17).
I wait for the answer from support service of Lenovo.

Re: V510-15IKB Laptop Freeze

I have installed the latest microcode update from Intel, which is supposed to have fixed the hyperthreading bug, but freezing continues. Chances are that the freezing is not due to the hyperthreading bug. How do we request a formal Lenovo response in this thread?

Today I have asked a question to technical support of Lenovo, and have pointed to this thread.

Re: V510-15IKB Laptop Freeze

I'm using this config and there are no freezes and no glitches but also no hardware acceleration in apps

 

Section "Device"
   Identifier  "Intel_no_DRI"
   Driver      "intel"
   Option "Accel"  "true"
   Option "DRI"  "false"
EndSection

Accel is ON but DRI is OFF

Re: V510-15IKB Laptop Freeze

Either way, that's only a Linux solution, and also a one that seems to negatively affect the system. I'd test it but the BIOS update unfortunately overwrote GRUB, sigh. I also think PRIME won't work as intended without DRI turned on. In Windows I have tested turning off PCIe Link State Power Management, but it did not solve the issue. I am currently testing the capping of maximum processor state to 95%, but that would only be a Windows solution if it worked. If it's really a Kaby Lake graphics problem, then it would in the meantime at least help if in their next BIOS update Lenovo allows us to solely use the discrete graphics card?
