My laptop (Lenovo Thinkpad W530) has been experiencing intermittent shutdowns, starting a couple of months ago.
These shutdowns (and sometimes freezes - which eventually shut down the laptop) increased in frequency from a couple a week to every couple of minutes. Shutdowns can sometimes occur immediately once the OS starts, right after the initial Lenovo startup screen.
The laptop can enter periods where it will continously shutdown after the first shutdown occurs (if more startup attempts are made), and after this period can work for 10 mins - a few hours. These shutdowns occur after the start screen, however.
I have:
- replaced the stock drive with a new Sandisk SSD
- installed Kubuntu (from scratch, new HDD), was previously running windows 7 on previous HDD
- Checked temps w/ sensors on Kubuntu, they stay within acceptable bounds until the shutdown occurs (max 45-55 deg Celsius)
- Used different batteries, and ran on and off AC power, with and without a battery
- Changed from "Nvidia Optimus" (aka Switchable graphics in the BIOS, which switches between Integrated and Discrete graphics), to always running on Discrete graphics
- Turned off the option in the BIOS that auto-reactivates NVIDIA Optimus
Note : The computer does not undergo any shutdowns while in the BIOS
Note (After turning off Optimus): After a shutdown, the laptop will now shutdown a few times instantly after turning on, before the launch screen, and shutdowns are sometimes correlated with moving the laptop, but at other times it can be shook/moved without any problems.
I assume that this may be a motherboard problem, possibly correlated with temperature.
Specs:
- OS: Windows 7 and Kubuntu
- Laptop: Thinkpad W530
- Memory: 4 GB RAM
- CPU: Intel (R) Core i7-3720QM (2.60 GHz)
- SSD: Sandisk (replacement, used to be stock)
- Video card: NVIDIA Quadro K1000M

Which OS are you running when it does this? – Moab – 2016-02-19T21:58:23.987
It occurred when i was running Windows 7, and when I changed to Kubuntu. – AAA – 2016-02-19T21:59:38.953
1Have you Tested your RAM? Take one stick out and see if it occurs then do it with only the other and Determine if one of the sticks is bad. – NetworkKingPin – 2016-02-24T06:45:52.860
I am not located with the laptop right now, but I will attempt this ASAP. – AAA – 2016-02-24T18:42:58.073
There's only one stick, will purchase new RAM soon. – AAA – 2016-02-27T18:45:05.050
I have a similar problem with my w530. Today it started to behave weirdly, but it has happened before: just after I launch Ubuntu from the grub bootloader it shuts reboots, or sometimes the screen turns black with a few pixels blinking. Sometimes it reboots before the boot loader has started. That happens more often if the power cord is not plugged. Did you figure out the reason for your problems? – Rulle – 2016-07-14T20:13:01.220
@Rulle I never ended up purchasing RAM because it might be a motherboard problem (I've also been putting it off). The same might be true for you. I never experienced any pixel blinking, but the reboots at all stages at startup is definitely something shared between our machines. Does your machine shut down when in BIOS? – AAA – 2016-07-15T22:43:39.850
Have you ruled out overheating? – Nemo – 2018-08-05T09:22:59.913
