Computer won't use dedicated GPU... Tried almost anything

[StoreB]

Because vBIOS is embedded with main BIOS, GPU will still show even if it's in Lala land.

"GPU not running" is the symptoms. Browse Lenovo laptop forum. There are plenty of cases like yours where a Lenovo laptop that's about 3 years old having dGPU issues (Not running).

I feel like Lenovo have a time bomb on GPU.

I'll check it out thanks, and yeah, when I decide to buy a new computer it first of all won't be a laptop and second of all it won't be a Lenovo

That's a good idea. You stated it ran fine for 3+ years? Try a reset of the BIOS. If that doesn't work, the updated BIOS for the Z50-70 here: http://support.lenovo.com/us/en/pro...ries-laptops/lenovo-z50-70/downloads/ds100528
This update is from 2015.

What OS are you running?

Also check the battery may need replacement( it ran it lost saved settings).

Laptop in general is best when it has only one source of heat (CPU). dGPU in laptops do tend to die prematurely due to lack of cooling not just on the chip but components around it.

It's not just for Lenovo. The issue is that Laptop makers are trying to make them look too good (slim) and scarifice cooling in progress. Clevo brand laptops are pretty much immune to dGPU dying.

Clevo brand laptops are pretty much immune to dGPU dying.

Also my Asus G750 gaming laptop still going strong!

Aight, thanks! I might go for another laptop, since I'm a bit of a bed-gamer, and I will defenatly check the Clevo Laptops out (never heard of them before)!

Also check the battery may need replacement( it ran it lost saved settings).

The battery is working properly, but it has lost some capacity over the years, that's the only issue with it.

Also my Asus G750 gaming laptop still going strong!

My mate has one of those, and he sais it works perf! Going to make a list of possible lappys, I'll write it up

Asus gaming laptops didn't had any air intakes at the bottom, so they would be ideal for "bed-gaming", just not sure if they still build them like that though, check it at some store.

I got a 11 years old Gateway laptop with dGPU. I think it's 8600m GS or something. It's 10kg but it still works.

On the other hand, my Lenovo with 650m died after 3 years. (Sounds familiar?)

My Clevo 13.3 inch with 760m worked well before I sold it on Ebay.

Lenovo cheaps out on components.

Unlike the Dell XPS Gen1/Inspiron 9100 which had 3 deep fans and heatpipes on the M 18GPU.

Obviously, there are cases where laptops are/were built for dGPU in mind.

But Lenovo ain't one of'em.

Stupid question incoming: Did you check to make sure the laptops power savings mode was set to "High Performance". I have seen to many cases where even on AC power people turn that down and the GPU wont spin up.

I have a feeling the gpu needs to be replaced. No wonder I haven't had a new laptop since 2004.

This should be done with all computers, same with link state for pcie

I had a similar issue. What my issue was with with Windows 10 but did you list the OS?
There is a setting either Xbox app or WMV app.

I can't say for sure this is the link as my work blocks everything game related, but it might point you in the right direction.
A few months ago i click "Disable" something within the app and everything started working correctly again.

To be more exact i believe this is it 'THE DVR SETTING" TURN IT OFF

Now I've gone over all the power settings again, and it's all set to high preformance. And it ain't a stupid question, it would be sweet if it's just a minor option setting that causes the problem!

Yeah, sorry for not listing the OS, but I run Windows 8.1.
Is this only an issue on Windows 10?

this isnt making sense, especially if valley is using the gpu & performing as it should be, that means it cant be hardware

Cant choose Nvidia GPU in Nvidia Contol Panel

Laptop: Lenovo Z50-70
Integrated GPU: Intel HD 4400
Dedicated GPU: GeForce 840M

My Lenovo laptop has been working for about 3 years now with a few minor errors along the way. But yesterday i came home from school (laptop worked perfectly at school) and was about to play a game of CS:GO. I usually get about 140-160 fps, but now I got about 20-30 fps. I checked the Nvidia Control Panel to see what GPU my computer was using, and although it was set to use GeForce 840M it still uses Intel IGPU...
I downloaded the GPU-Z to check if it used the Nvidia GPU at all, and yes it surprisingly did, but only when I ran "Valley Benchmark". It won't use the Nvidia GPU even though I disable the Intel HD 4400.

When i check dxdiag it says that the screen uses Intel HD Graphics Family and under reproduce it says it uses Nvidia GeForce 840M, not exactly sure if this gives you lads some hints about my issue, but it might be worth telling.

What I've tried so far:

NVIDIA Control Panel:
-Set the global preferred GPU to High Performance NVIDIA GPU
-Set the power management to High Performance

Intel Graphics Control Panel:
-Set 3d to Performance
-Set power management to High Performance

Windows Control Panel:
-Set power management to High Performance

Software Installation:
-Installed Lenovo outdated Intel and NVIDIA drivers
-Uninstalled and Reinstalled Current Versions Intel and NVIDIA Graphics Software

If it helps by showing some pictures from Nvidia CP, GPU-Z or just anything I could throw those in a comment.

I realy appreciate it if someone would be so kind and give me some help here!

Thank you in advance

You wouldn't by any chance have changed Operating Systems have you?
The reason why I ask, is your Laptop is nearly identical to mine and I had problems like you did when I uninstalled the crap Windows 8 that was pre-installed on it, and put Windows 7 on it....as soon as I did that, the Nvidia control panel showed up half empty, the Intel graphics card became the default etc

I think it has something to do with the manufacturer only having the correct drivers for Windows 8, with NO support for Windows 7 on the Laptop

Anyway that was my experience, yours could be different

I haven't changed the OS, was pre-installed 8.1 (which is kinda sad). So drivers and all should be good. Would have been sweet to go back to XP though
