Feedback on the Dell Inspiron 3551 - Iris 15 BTM

Asked by Nishanth S

I use Dell inspiron 3551 ubuntu installed laptop.

We I update ubuntu packages which also include kernel update. When kernel is changed, Laptop boots up successfully. But within an hour laptop freezes and capslock light blinks often.

So, I did dell recovery. Laptop works without flaw.

How to disable kernel related updates for my laptop so that it doesn't freeze often?

Is there any alternative kernel update repositories for the laptop???

Hello,
did your laptop came with Ubuntu installed?
For now you can simply un-check the kernel update in the update-manager to skip it, but it will be great if you can provide some information for us to fix it. To do so, you will need to boot into that buggy kernel and run "uname -r" in a terminal (Ctrl + Alt + t) to get the kernel version.

If you can reproduce this issue, please open a bug with "ubuntu-bug linux" command in a terminal with a brief description for how to reproduce it and what will happen. Then link the bug report here (or just paste the link here).
Thanks!

Yes. My Dell laptop was installed with ubuntu 14.04 (factory default).

kernel version after update was 3.13.0-58-generic.

As if now 3.13.0-38-generic kernel is good and smooth. The kernel provided by dell as factory default.

I notice the same issue after installing ubuntu 14.04 from http://www.ubuntu.com/download/desktop instead of dell factory default ubuntu OS.

Will 16.04 LTS be compatible with my laptop?

Hello,
I managed to reproduce the kernel panic issue here (maybe it's not exactly same with yours), please refer to the bug linked here, and please feel free to open a new one with command "ubuntu-bug linux" in a terminal if you think your situation is different.
Thanks!

hi nishanth,

I have the same laptop, and I faced a problem during upgrade.

I was trying to update ubuntu from 14.04 to 16.04. It does not show up for my laptop in supported devices for 16.04 version.
During upgrade the 2 dependencies failed, network-manager and network-manager-pptp

Not sure how to roll these back, the system did a partial upgrade and shows command line prompt, does not boot ubuntu desktop now.
Can you suggest what to do.

Can you help with this problem?
