*** Official Clevo P640RE/Sager NP8640 Owner's Lounge ***

The CPU load stays at 5-10% while using Chrome. Even before reapplying the paste, which by the way greatly helped. If you see the picture above, it barely had anything on processor and the graphics card, it was all on the sides dried up.

 

The video cable weared down. It is very common with this laptop - scroll this topic up or search for my posts. You need to bring your laptop to your reseller for cable replacement.

 

5-10% is a pretty high background usage.

 

Yeah, I know. I recently noticed that the audiodg.exe and PresentationFontCache.exe were eating up a lot of CPU, it's caused by Logitech's Gaming Software and Visual Studio. I managed to fix both thankfully without needing to do a clean install of Windows.

 

Just throwing this out to fellow P640re owners, on the off chance one of you might be using Linux.
Simple question, does anyone have any information on enabling the optimus graphics with xorg? Currently, if I do an optimus setup using the NVidia-drivers, I get to a blackscreen. xrandir reports no devices. I can get a functioning screen with no config using xorg-x11 opengl drivers, but then I get no graphics acceleration. So anyone got any experiences that may help?

 

ya, i have the same issue. one thing that i tried was changing it then rebooting. sometimes it worked, sometimes it didn't. have you looked into using prime-selector? also, try using the x-org updates ppa. they tend to have some of the bleeding edge stuff and i've had some luck in that area. but i have also bricked my install with it too. just be prepared to drop to console to fix whatever ya f**k up LOL.

 

Unfortunately, I don't seem to have access to either of those, as I am instead using a gentoo install. I was more hoping that someone had a working xorg.conf they could share that will actually function for me.

 

does clevo p640re has intel DPTF driver?

 

Hi guys,
I bought a P640RE right when it came out, with an i7 6820hk and a gtx 970m. A week ago I got home and the machine wouldn't turn on. Called the seller, and after testing they had to send the barebone to wherever Clevo's factory is. The thing is, what will happen if there is nothing to do? It is still under warranty but there aren't any of this type around. You only see the gtx 1050ti with a i7 7700hq, and in my eyes I would be losing if I got one of those because I lose the unlocked cpu and the better gpu. What are your opinions? Should I ask the seller for a discount because I got the bad side of the deal?

Thanks guys, hoping for a reply soon

 

I would check to see what they can do for you first under warranty. It might be possible that they still have access to the i7 6820HK / 970m motherboard or can fix it with another type of repair. But if they aren't able to, then see what options they might be able to do for you.

 

Thank you for the fast response!
Do you think I would be at a disadvantage if the seller offers me the gtx 1050ti with a i7 7700hq? If so, should I ask for some sort of material to break even? (ssd, ram, ...)
Or am I being too strict and that version runs equal to mine?

Thanks once again

 

The 1050ti is on par if not a little faster than the 970m.

 

I love this site for an example. But you can check out gaming performance here to see how cards stack up.

https://www.notebookcheck.net/Computer-Games-on-Laptop-Graphic-Cards.13849.0.html

 

My problem is the premium I paid for the unlocked cpu that is not available, at least for purchase.
I will contact the seller tomorrow because they are already closed.

 

i understand the frustration of paying the premium for a proccie that isn't available. but also from personal experience i don't see the benefit of placing an unlocked CPU on a BGA platform, its a horrible idea to overclock on BGA.
on a side note, im sure the retailer would be willing to work with you in regards to finding atleast some sort of common ground if they don't have a 6820HK board available.
i've learned that a lot of the dealers here are pretty reputable and take care of their customers.

 

A tuned 7700HQ would still perform very well with the 1050ti and in general but as above I would talk to support and ask them about options.

 

Did you have any luck with this?
I'm trying to figure out ways to fix my terrible linux battery life - I have a feeling knocking out the discrete graphics card with optimus would be a decent way.

Sadly I can't seem to figure out how to get the prema mod now that the thread is over

 

bbswitch successfully disables the Nvidia card. Also be sure to install kernel version 4.11 as it has the NVMe powersave patch which lowers power usage for 1-2 Watts.
In my custom "extreme powersave" mode (Nvidia card offline, 2 of 8 CPU cores online, 1% brightness, and some other powersave tuning) my laptop consumes 8-11 W thus battery life is 4-5 hours.

 

Yeah turning off the dGPU alone would help save a huge chunk at idle, you wont get huge gains without that.

 

Oh damn, I'll have to give bumblebee a shot, cheers.

 

There is no such thing as a highly power efficient at idle GDDR5 bus (when compared to DDR3/DDR4).

 

webupd8 has a pretty good walk through for getting it working, also down towards the bottom there is a link to nvidia indicator which will provide an indicator telling you which graphics card is active.
it should work with 17.04 as well

http://www.webupd8.org/2016/08/how-to-install-and-configure-bumblebee.html

 

Didn't realise that 17.4 was released
"
GNOME 3.24 comes with support for machines that have two graphics cards. If you have this hardware, you can now select which GPU to use when launching an application. Settings will also give information on both graphics cards.
"
Now that's interesting

 

hmm, i wonder if that covers optimus graphics as well. might have to give it a try this weekend and see how it works. if it really is a viable option then im saying hasta la vista to winblows 10

 

Once again I need some help.
Just got into college and need to run linux (the PCs there run Lubuntu/Xubuntu and I will run the same to minimize compatibility issues in projects), and I will be dualbooting between lubuntu and windows10.
The thing is the laptop barely reaches 3 hours in windows 10 and I heard that linux is way worse.
Any way to improve battery in linux(lubuntu)? I don't know much about linux so I would appreciate some tutorials to implement the tweaks. Any possibility of reaching near the 3 hour mark? I want to disable the dedicated gpu too, like you guys said (is it possible to toggle it on and off without rebooting?)
Thanks

 

If you use NVMe SSD then first of all install Linux kernel version 4.11 or newer as it has the NVMe powersave patch which lowers power usage for 1-2 Watts.

Then adjust this script for your needs:

Code:

You must run it as root (or "sudo sh script.sh"). Do not worry about disabling 6 CPU cores — the i7-6700 is so powerful that just 2 cores is more than enough for normal usage, I even run a virtual machine with Windows XP without any lags or freezes.

This script will make your laptop consume ~10 W so battery life will be ~4.5 hours.
Also run "powertop" and act according to its suggestions.

 

which build of nix did you test this on? i might consider tweaking it a bit and running it myself.

 

openSuSE

 

if i read the script right it should work just fine on an ubuntu build, right? it looks like it references a lot of the same processes (im not a linux guru, i just have some experience)

 

It should work on all distributions with minor edits as most distributions have the same paths specified.
If it will return "no such file or directory" on some line - find the right path (e.g. "find /sys/ -type f -name no_turbo") and post it here for fellow Ubuntu users.

 

thanks, ill give it a try this weekend

 

Is there any way that you could tell me how to change the kernel?
I tried to install xubuntu alongside with w10 but after the install and it telling me to restart, the computer just freezes when I click the restart button and when I force it to shut down and try to login, it freezes in the blue default background after I login (the mouse still moves, but I have nothing to do besides a completely blue screen and the fans raging)
I know, complete noob... But I love this machine and need it to run linux

 

For someone new to this, What I got is that I need to install the OS, update the kernel(No idea how it works) and then just run a script that I create by copying all that code into a word editor and naming the file "script.sh"(Do I have to run it every single time I turn the pc on?)

 

hi.can can you help me where to get the prema bios?as i see you already have it.i cant find any info about it
also how many post do i need to send pms?

thanks

 

If you are installing fresh xubuntu build than you do not need to update the kernel as there must be a fresh kernel already.
About the freezes - seems that you are having this issue: https://github.com/Bumblebee-Project/Bumblebee/issues/764
In short - you should add something like

Code:

acpi_osi=! acpi_osi="Windows 2009"

or

Code:

acpi_osi="!Windows 2015"

to the boot parameters.

Yes. You could easily add it to the autorun, but I don't know how to exactly do that in *ubuntu, google it.

Send him a PM

 

Send him a PM[/QUOTE]

how many post is required to send pms?

+ where is the location of the second m,2? slot for the lte modem? addig an m.2 ssd in that slot is possible?

 

I don't know.

It should be soldered between the battery and the motherboard, in the lower-central part of the motherboard. If you don't see it - it means that your Clevo reseller did not opt for second m.2 slot.
Search this thread for "modem" or "m.2" and you'll find photos.

 

thanks.one more thing:every time i wake up my xmg p406 from sleep the sound is gone and i have to restart every time to solve it.the windows 10 is fully updated and the sound driver too.am i the only one with this issue?what could be the solution?

 

anyone?

 

Anyone encountering issues after updating Windows to Version 1709 "Fall Creators" update ?

After upgrading, my Nvidia GTX970M stopped functioning. Any game which relies on the Nvidia GPU will crash. I used the Nvidia Control Panel to force the game to use the integrated Intel HD 530 and it worked.

 

Have you rolled back the update to test if it was the cause?

 

You see, the problem with this update is there are hundreds of file and registry changes that happened often leading to random issues here and there. Also, although it just sounds like a Windows update, it's a whole new build, so the drivers like the LAN, WLAN, Bluetooth, Card Reader, VGA, have to all be updated

If you manage to update you drivers, and still face these issues, try this:

How to properly update your nVIDIA graphics card driver

If that also didn't help fix the problem, then you need to do a clean install:

NBR Windows 10 Clean Installation Guide
Windows 10 Tweaks and Fixes (Index post #1)
Phoenix Software Updates

You can get a lot of the drivers from the below thread as some of them work on multiple laptops like the Wireless or Intel Chipset Drivers. Also depending on what card reader your laptop has, you may be able to use the Realtek Card Reader drivers from this thread as well:

MSI GT73VR 7RF TITAN PRO Drivers

 

Hello guys
First, gotta say I'm really happy to find this sub ! I love modding my p640RE and had a few questions for you guys :

1) Is there any site proposing spare parts ?
2) In any case, where could I find a top case ? (in case of modding gone wrong AHAH).

Thank's

 

Hi, I am desperate for a P640RE one... I am missing HDD Password option in the original one (PC Specialist, v10).
I tried to mod it myself but could not flash it back (protected?). I tried to send you PM but I don't see how to do it here
Maybe my account is still too new.

(I know the BIOS is able to handle the ATA password because when I insert protected HDD in the notebook I get
the password prompt. But the algorithm used to translate keycodes to password is usually different machne to machine)

 

Why not use something like bitlocker?

 

Bitlocker is software based and therefore takes CPU.
I have Samsung 850 EVO which has hardware AES encryption. In fact, the drive is encrypted
anyway, but it you set the ATA password then the symetrical key for AES gets encrypted and protected
with this ATA password. So basically, once you set this up, you get hardware based encryption in
a very secure way and also a solution that does not in any way affect performance.

 

The 850 EVO can accelerate bitlocker IIRC.

 

Hey everyone!

I know this is not tech support, but I was wondering, did any experience flickers on their laptop monitor before? I am 100% sure it's a hardware problem, I was thinking it might be a loose wire. (I clean it every month or so) I owned this beast for 1,5 year now and I just started getting this problem. Whenever I am moving the lid it occurs.

Any help is appreciated, thanks!

 

Yes, it is most likely that your LCD cable is loose, and needs to be re-seated.

 

Do you know where that cable is located on the motherboard? I am having trouble finding it.
