Windows 7: New Lenovo Laptop Died While Rendering Files (All 8 Cores Being Used)

New Lenovo Laptop Died While Rendering Files (All 8 Cores Being Used)

Hi all,

Recently purchased a Y700 15isk
(i7 6700HQ (2.60 GHz) 8 GB Memory 1 TB HDD NVIDIA GeForce GTX 960M 4 GB GDDR)

The machine came with windows 10 and I partitioned the system and installed fresh copy of windows 7 and windows 10 (dual boot).

So over the weekend I decided to build overviews (via software) of my music collection. Since the laptop has 8 cores, it was building 8 at a time. So I imagine that the system was working full throttle. About 2 hours into the project, the laptop completely went out. Suspecting a heat issue, I checked the brick, it was hot but still was giving me a power reading via my ohm meter.

Plugged the brick back into the laptop and the lights on the front of the system did not turn on. Anyways pulled the battery from the laptop and did a discharge cycle and nothing.

I suspect my motherboard or cpu went toast! Seeing that I will be using this new laptop to dj professionally, obviously I am glad this happened at home.

Anyone have any thoughts on this? I can't believe that a new gaming laptop would fry while working all 8 cores. Fans also seemed to working while this was happening. In the power settings I also remember setting it "performance".

What are people using to stress test laptops? I will be sending this one in for repair and then stress test the one I get back.

Laptops never has a good cooling system and always run hot.
The CPU has a temperature trigger that will shut down the computer to self protect.
As it also has a battery, I would say that is probably the internal power supply. When plug ed in, does the charging led goes on?

No reason to work on performance profile settings.
You can run on balance profile settings and adjust the minimum and maximum CPU clock. I suggest 20 & 100%. The clock then will automatically be set as necessary.

The i7 6700HQ has 4 cores and Hyper-Threading makes two tasks share one core, simulating 8 cores.

Hyper-Threading is only effective with high multitask programs, like Photoshop, Autocad, games etc, that split a complex task into multiple tasks.

Install a hardware monitor -

Thanks for all the info Megahertz07!

No the laptop does not show a charging LED after it stopped working.

Interesting comment on the profile settings.

I am using serato DJ, totally forgot that it does use hyper threading (duh). It definitely was using the hyper threading feature because I could see 8 songs getting overviews being built.

As the charging led stopped working, I would say that the problem is on the internal power supply.
Use this hardware monitor. It's more simple than HWinfo and It can be set to show the CPU case temperature near the clock.
Unzip and move the OpenHardwareMonitor folder to Program Files (x86).
Run OpenHardwareMonitor.exe and configure the settings you want to see.
On options tab, select to run on Win startup

Laptop died with an error
But I don't know what it is. Last night, I was trying to discharge my battery to see how much life it has left. It shut down suddenly, and I thought it was normal, so I plugged in power and left it off so it could charge. This morning, when I turned it on, it took me to the Windows Error...
