Lenovo Y520 7300HQ Turbo Boost Problem

Hello i have a Lenovo Y520 80WK014PTX;

Processor: 1x Intel Core i5-7300HQ Processor(i5-7300HQ)Memory: 1x 16GBDDR42400Operating System: Windows 10 Home 64(TR:Turkish,EN:English)Hard Drive: 1x 128GB PCIe 

P920 not booting after installing ARC-1883 controller

Dear all,


I have acquired an ARC-1883 RAID controller for my P920 workstation and after installing, the booting process does not complete. In fact, I cannot even enter the BIOS setup.


I have tried on an old P900 and it works fine. Do any of you have an idea what can be happening?


Thanks in advance

lenovo y720 – external monitor issue


(laptop specs: i5 – 7300hq ; gtx 1060 ; 16gb RAM dual channel)


In the past few months I am keeping my laptop connecting to an external monitor.

When the laptop is connected to an external monitor I had notice that the desktop performances are not smooth (when I minimize a windows for example or even turning on exetreme cooling). The laptop lid is clossed.

All my drivers are up to date (gpu driver  – 417.35),  Windows is up to date ( build 1809).


To troubleshoot that issue I already tried a few things..

I am using an original mini display port cable of lenovo (I had tried other cable as well).  I had also tried to to use a hdmi cable instead.. no difference here.


The problem is solved when:

1. The laptop lid is open (when connected to an external monitor).

2. When I restart the computer (if I turn off the laptop and after that turn on the problem is not solved.. only when restart..)


From the 2 scenarios that I mentioned, I came to conclusion that the problem probably stems from a violation between the dedicated GPU and the intel hd GPU. When the laptop lid is clossed only the gtx 1060 is operate.. but when I open the lid the internal gpu operate as well. When I restart the computer the laptop lid is clossed all the time.. but when I turn off the computer and than turn on I must open the lid first..


Is there any settings that I can change to solve this problem? or is it really a bug?

Lenovo Y720 – low frame rate (FPS) in games – GTX1060

Have a Lenovo Y720 laptop with i7-7700 cpu, NVidia GTX 1060 GPU, currently 16GB RAM.

Some tips troubleshooting various frame rate issues in games:


1. Instrument things – install MSI afterburner with RivaTuner (make sure you include this) and you can set a hotkey to display the frame rate, GPU MHz, GPU temp and and similar metrics. Also add these for CPU. Turn this on in game and pay attention to overheating of either GPU or CPU, or whether the MHz of GPU is fixed or increases. For example, in BF5, I found that my GPU was fixed at 600MHz, no matter what I did, and that I was only getting 30FPS because of this. Evntually I used a tool called DDU to remove NVidia drivers, and found an updated NOTEBOOK SPECIFIC release of GEForce GTX drivers on the NVidia site. This finally let the GPU run at top frequency which solved the FPS issue.

2. RAM – initially thought my problem was lack of dual channel ram, so added another 8GB stick to my 8GB RAM. This DID NOT solve performance problems. So I would be reluctant to recommend adding a 2nd stick of ram to a machine that is suffering huge performance probelms. Perhaps it can help as a last resort, or may have marginal gain, but my issues were entirely unrelated to having 2 sticks of RAM.

3. Furmark is 3D analysis tool – even before running a game, validate your cooling, machine configuration, and GPU performance using this tool. You should see your GPU temp go from say 35C to 50-60+ Celcius as the test runs. The MHz of the GPU should go to 1200 or more, not stay stuck at a low value like 139MHz or 600MHz or somewhere in between. You can compare your GPU to other tests online, so will tell you if something is dramatically wrong or not.

4. Second monitor, display port vs HDMI, disable integrated GPU – I read suggestions on the forums that suggested doing things like disabling the built in graphics adapter such as Intel HD630 that is part of the CPU/MB (Kaby lake class CPU in this case I think). I tried a few of these suggestions like running on the laptop screen, changing the laptop screen resolution to a lower setting to match the game, unplugging the display port, disabling the HD630 graphics chip in Windows Device Manger and so on. NO EFFECT on my root problem of a fixed frequency GPU. Only updating the drivers solved my issue.

5. Various power option configuration – just to be sure this is not causally related to your problem, ensure that performance is set to maximum in both battery and plugged in configuration, at least during troubleshooting. Once you solve an issue, you can revert settings back to presonal preference.

6. Cooling – my CPU was overheating in games, even with the Lenovo Nervesense extreme cooling fan setting (where fan spins up very high). I added one of those USB powered cooling platofrms (where your laptop sits on top of fans) and it made a difference of perhaps 6-9 degrees C I think. I would recommend this as the cost:benefit ratio is low (ie. cheap to add $20 worth of cooling for a device worth $1000+). 


Hope this helps someone when their stuff isn’t running well, and they do not know how to methodically tackle the analysis side of things. Start with measuring – you MUST know temps, MHz of GPU/CPU, and frame rate to ensure optimal performance.
