First post here. I have the 16gb version of the C940, but the typing experience on the keyboard sounds very hollow in the center, and I may exchange or return it. I am curious if anybody is able to answer on the RAM configuration of the 12gb model. Does in run in single channel (12gb), dual channel (6+6gb), or intel flex mode? I asked a gentleman at a retail store and he looked at me like I was speaking a different language. Thanks!
Hi All, I got my L390 a few months ago, and I have found that I either have the choice of windows awful microphone audio enhancements, or an otherwise great sounding microphone with a loud beeping..  I didnt think this was something that still happened with laptop audio so I came here. The mic itself sounds great, very crisp sound and I can hear a lot of detail, however something is causing a lot of interference...  I have the latest audio drivers so I dont belive these are the issue... Is this the case for anyone else? This is specifically with the windows audio enhancements off. 
Hi there,
It's a real shame this tool is being deprecated. I'd quite like to download a copy of the

Operating Guide documentation for future reference but the "Download PDF" link appears to be broken. It always returns a 0 byte PDF file for me (tested
on multiple browsers). Can anyone from MSFT please advise?
Thanks in advance!
Hey all, I am not 100% sure this is a Windows 7 issue however my computer will not shut down. When I go to "shut down" the computer goes to shut down and the screen turns black. The computer itself does not shut however. (Fans and lights stay running) Any idea on how to remedy this issue? I been manual shutting down the computer with the button. (Pretty sure Im crashing the thing each time) I don't want to hurt the ancient computer, lol can anyone assist me please?

Thanks, Thomas
My device is: Lenovo ThinkCentre E73  The greater the load, the greater the chance that the machine will freeze! I recently installed Windows 7 64x on my machine but still there is a problem! i took the graphics card out of it and it still freezes at a higher load but if i just browse the internet it will go away for days! I also ran a CD RAM test but nothing went wrong! USB ports don't work, they make windows feel like plugging in and out of USB devices (I'm currently installing operating systems using an optical drive)! I have put the BIOS back to factory default once (I even removed the button cell)! If anyone could help, I'd appreciate it! It's impossible in PhotoShop, to render and play video on your computer!   Thanks in advance for the answers!
Has anyone notice the thin grey horizontal lines in the background of the lcd panel especially with light colors? Whites seem grey in color. I'm not sure if this is normal or not? I was expecting more colors and and better contrast out of this panel than my 5 year old Yoga 14. The whites on this my old Yoga 14 laptop panel is better than this new laptop. Other than this everthing else is great but if this is normal not sure this will be a keeper.

I've been using my p1 gen 2 for about a month now. First, the screen turns black whenever I plug or unplug my charger cable. It's always been like this and hasn't been much of a bother until I unplugged the charger while on a video chat. The screen turned black and stayed like that for a longer period of time and I had to plug it back in for the screen to turn back on. It also ended the video chat.  Sound lags and breaks. So far I've only experienced this on Youtube. This one time the sound started lagging and my laptop froze. I had to restart my laptop. I get nervous everytime the sound starts lagging now.   This is super frustrating and disappointing!!  Did anyone experience similar things with their thinkpads? Please let me know if you guys know how to fix this  
I have the Windows 8 x64 RTM installed on hardware using the Intel E208B284 Controller Hub. The hardware below is also listed as the C216 or BD82C216 chipset. Windows 8 runs well as an EFI booted OS, but I can't get the "High Definition Audio Controller"
working. The error I get is:
Device PCI\VEN_8086&DEV_1E20&SUBSYS_72708086&REV_04\3&11583659&0&D8 had a problem starting. Driver Name: hdaudbus.inf
Driver Date: 7/25/2012
Driver Version: 6.2.9200.16386 (win8_rtm120725-1247)
My understanding is that this is the Microsoft UAA driver mentioned in this article (http://www.intel.com/design/chipsets/hdaudio.htm) "Microsoft* has chosen Intel HD Audio
as the main architecture for their new Unified Audio Architecture* (UAA), which provides one driver that will support all Intel HD Audio controllers and codecs."
The hardware in question is a 2012 retina MacBook Pro (model 10,1)
Any chance of an updated driver?
Is there a link where I can manually download the new version of Windows 10 (1909). I have been checking my updates daily but have not yet gotten the new update version to install.
My sister never registers anything. She bought MS Office for a computer and now she's replacing that computer but has no MS account etc. Is there any hope for transferring this? (It is a totally legitimate MS copy.)
I have searched multiple resources in an attempt to resolve this issue and have come up short. I have a Yoga Pro 2 running Windows 8.1 64bit and the integrated web camera is no longer working in Google Hangouts. I have tried in Chrome, Firefox, and Internet Explorer with no luck. I have reset my browser settings back to the defaults and the camera still is not working. The camera works without issue in the camera app as well as in the GoToMeeting app, but does not work in GoToMeeting when asked from a web browser. The most common solution I have found is to update the camera setting to normal in the Lenovo settings, however I do not have an application called Lenovo settings on my computer and have been unable to find where I can download this. I tried running a scan of my device on the Lenovo support page to see if I required any driver updates, however I get a "scan failed" error message and cannot proceed any further. At this point I am totally stumped. And any insight would be greatly appreciated.

Hello all, I'm having trouble talking to my main NAS machine over my network, for help explaining ive drawn a diagram.

My problem is between my windows machines and my NAS, as outlined, all the hardware between me and the NAS should be rated for at least 72mb/s if not more and yet my max speed on either of these devices is 10.1mb/s at best, what on earth could be the problem? Ill admit im not a network genius.

My laptop has a SSD with a write speed of over 100mb/s
My NAS has 6 drives in a raid array with a total read speed of 124mb/s
Thanks so much for helping
Hello, thanks for looking at my thread

I've had a Gigabyte RX550 for a little over a year now, and yesterday it stopped working.

I get no signal to my monitor, but the windows boot sound plays. Interestingly, I get signal when I boot in safe mode. I've tried uninstalling the drivers with ddu, and the machine boots normally with signal to the monitor, and the fan runs, albeit in 640x480.

When I install the latest drivers and boot, however, the fan doesn't run and I get no signal to the monitor. I have gotten the same result with 3 different versions of the drivers.

Any ideas? Thanks in advance.
Hello,Im using the Ideapad C340-15IWL and Im writing on it using the Lenovo Active Pen 2 and every time I touch the screen (after turning it so the keyboard is behind the screen facing down) it shakes so what Im saying is if there is any holder for it to contra it so it will stop moving? For now I put books to stop the shakes but is there any offical device or holder that can help?
Hello, some questions to the new file system ReFS:
Im using ReFS in Win 8.1 Standard Edition with a single 4 TB HDD.
I want to know how and where ReFS reoprts a defective file that is detectet (e.g. with the scrubbing process) ?
I have read that ReFS makes a log entry when it detects a corrupt file (when checksum does not match). But nowhere is to read where I can found this log ...
It is everywhere to be read that ReFS performs a disc scrubbing to detect corrupt files. How often runs this process? Can I configurate when it should run? 

By the way:  In my system I never saw the hard disc running for along time what would announce that a scrubbing process scans all the 3 TB stored data !!!   So I cant believe that this function works ...

Can it be that this functions are not implemented with ReFS in Win Standard Edition but in the server version?

Ive asked the german microsoft hotline many times - they werent able to help me. I wrote this questions in german sociel.technet forum and in german answers.microsoft.com forum and haven't got an answer yet.
Many info about the functions of ReFS are written but nowhere how this functions can be used. Does microsoft has no interest on someone who is testing this file system?    Further more I found a bug: If the letter appears in a file - the
file is then not deletable any more...

So I dug up a 10 year old Acer One.
I need it to do very basic things and I've done my best to update/fix things but I'm out of ideas. Runs on Windows 7 Family E.
What I've done so far.
- Total of 95 updates for Windows 7 completed.
- Deleted all non-essential software
- Disabled start-up programs and services that frees up the CPU.
- Tried to do a defrag but it jams at 28%

It still tops out at 100% of of CPU usage for very basic tasks ( like starting Google chrome)
Even if it doesn't max out the RAM it still takes sometimes 10 minutes to do anything (like deleting software)
I get that this little old thing has limits but is there anything else I can do to make this notebook semi useful? Something to boost performance? Speed it up?
Hi everyone,I am wondering if anyone else has this issue with their x1 extreme gen 2 with i9. Long story short, my laptop seems to miss input from typing. I'll be typing something and a key press doesn't register. And before you point out, no it's not me. I've confirmed this has happened even when typing really slow. I have noticed it happens especially if the cpu is busy. It also happens with the mouse when trying to move, scroll, or drag something. Basically it's like every 10 to 20 secs, for about half a second, the laptop just refuses to process any sort of keyboard input, so you won't see a letter appear when you are typing. And you have to go back (hit backspace) and fix it. Very very annoying. I thought this was an issue with windows but I am dual booting pop!_os (linux) and it does it there as well. Does anyone else have this or know of a fix? This really sucks because besides this issue, I love this machine and it's very fast.
tried everything under the sun, internal cam just shows black screen, skype etc not showing cam either. updated drivers, privacy settings, etc etc. no clue what's up.

hi. I have a problem. my computer doesn't want to exceed over 8 gbs of ram even though I have much more to offer. for example, I play a game called rust. I have not seen it to this day exceed more than 10gbs ever. (but about 99.9% of the time it hovers at 8gbs.) while this may not sound like a problem, rust is a VERY heavy game and needs ATLEAST 10 gbs to be "playable", or at least I have read that on what I believe I remember is on face punch's (creators) official site. so, I get 9 fps on a 3d game where competitive aim is required. help. these are the specs the Sysinfo utility showed me:

Hi My Lenovo X200T suddenly stopped working yesterday  (after 10 year's!!!).  I was just doing something on Excel and it restarted of its own accord whilst I was working.  It booted up again and I started working again, but then it restarted like before.   Did it a couple more times, and then wouldn't boot at all.   So I opened up the machine and cleaned out the fan etc, reseated the RAM.  As you can see in this clip (https://youtu.be/nHHM569sI0w) it tries to start, fan turns for a bit, then turns off.  What you don't see in the clip is that the second time it does this, the fan then comes back on and stays on.  It sounds like the machine is working but nothing I'd happening on the screen.  I've tried taking the battery out, holding power button for 30s then plugging in AC and it makes no difference. Any ideas would be gladly appreciated.

My Lenovo Ideapad Z-710 has a strange battery charging issue. When the laptop is turned off and plugged in, the battery charges to 100%. When I power the laptop on, the indicator light shows it is still charging, but it actually starts running off the battery and of course the battery starts discharging. When the battery runs all the way down, the laptop shuts off. I have replaced both the charger and the battery with the same results. Plugged in with battery in place and turned on: Laptop will operate as long as the battery has some charge and shuts off when battery is depleated.Plugged in with battery removed and turned on: Laptop will run all the time.Plugged in with battery in place and turned off: Battery charges to 100%Unplugged with battery in place and turned on: Laptop runs normally until battery is depleatedAny ideas on what could cause this. I read somewhere that it has a battery switch board in it.  
HelloI have purchased Yoga S740-14IIL  and first thing I have found that camera is so norrow vertically. When you sat down on front of it and set the lid to your perfect position camera misses your head. And half of your head is displaying. These are the two different images that show the camera having same lid angle with my yoga and macbook.   This is huge different. Is it same for you guys for all win notebooks or just macbooks have this capability?

I am in a few fantasy hockey pools and am having an issue with links that will take me to my other teams. I can go to a team, but when I click on the link to another team it doesn't work. Sometimes I will copy the address of the team I am on, then open another window, paste the copied address and paste it in the address bar to get to my other team. Sometimes that doesn't even work. OPnce in awhile I can just refresh the page I am on and then click on a link to another team, and it will work. More often it doesn't work either. This is on CBS Sports Fantasy page. I do not have this problem on my other laptop. All of the links work on that computer. It seems to be this laptop that it does it on only.
Anyone have any suggestions?
I am using Windows 10
I am not getting any error message, the link just seems to be dead. When I click on a link it looks like there is a thin lined box around the link I want to go to but that's it. Zero indication that it is even recognizing my clicking on it.

Hi, my new Lenovo X1 Yoga 2019 has got a problem with the battery.Even it's fully charged, it sometimes shuts down immediately.

Hey everyone! So, my 3 year warranty ran out a couple months ago and I'm looking to purchase a new X1 Carbon to go with my new 16" MacBook Pro. I use Windows, multiple Linux distros and MacOS daily, both for work and for play. When I received my X1 Carbon Gen4, it was my first ultrabook; I wasn't used to seeing such high temperatures. It was sent in 3 times for "overheating" - the first time they replaced the fan, the second time they replaced the entire mainboard and everything accompanying that (CPU, etc), the third time they just did a software update.... Nothing ever changed so I just dealt with it. I was used to desktops with premium cooling, idling at 30C. As I type this, it's 39F outside, 68F inside, I have Brave browser open with 3 tabs and I'm running at 75C. Fortunately, even when I run World of Warcraft, it doesn't usually get above 82C or so. My question is this - has anyone owned both the 4th gen AND 7th gen, and noticed improved cooling? Or, improved cooling in any model past the 4th gen? I'll still probably get the X1 Carbon again (although I hear the 8th gen isn't too far out so I might wait for that, which will include the 10th gen Intel CPUs) as I've never had a single issue with it (besides the cooling). Best-in-class keyboard, although even after 3+ years I've rarely used it in non-clamshell mode.  I'm looking into the Razer Blade Stealth 13" as well. Not really a fan of Dell, although they've definitely redeemed themselves when it come... Read more
I've had my dashcam for a few weeks now and I've been viewing and deleting the files fine. After today, all the files are inaccessible and this message pops up in Media Player. I've tried opening them in VLC.. I've tried converting the files to AVI with no avail. I can't change the settings in Media Player to automatically find codecs because I have an older version and can't update it. I don't know what to do now.

I have a (second) computer with a gigabyte ga-p55m-ud2 motherboard.

The computer is used for the Internet and Office and there are no complaints.

A few days ago I started having a problem with the power on, and I can't hear the beep from the motherboard after which the picture comes up and the situation stays the same and the screen doesn't turn on.

At first I thought it was a video card problem, I swapped a card with replacement, moved it to the second video card slot with no success.

I tried a friend's advice to unplug and reconnect the battery on the motherboard and it didn't help either, and finally while playing, what solved the problem was disconnecting the power supply cable that connects to the motherboard (written next to it ATX and PCB)

The thing is, the problem is very often repeated, if I'm not mistaken, even if the computer is not in use and goes into sleep it doesn't wake up and restart doesn't solve the problem without disconnecting and reconnecting this cable.

Does the problem on the motherboard and is it actually dying? Because if it is a motherboard problem, it is not something that can be repaired / financially worth repaired / or within the warranty.

Maybe somehow it's a lot simpler (hope) and it ends up replacing the battery or something simple....

I have yoga 2 pro model number is 20266. It's great notebook but doesn't the speaker and mic for long time. I reinstall and tried almost everything. I would like to know if anyone can help this problem. Thank you,   
My Yoga 730 has worked fine for the past few months that I've had it. I got it in December and everything was fine. Today I was using it while playing the sims and it got to 15% and I plugged it in and it charged up to about 50%. at some point it stopped charging and next thing I knew my laptop was at 10%. It was plugged it but the laptop wasn't recognizing that it was even plugged in. most people are getting the "plugged in, not charging" but my computer isn't recognizing the charger at all. it was working fine all day then just randomly stopped. I've tried different outlets and restarting my computer but nothing is helping. my computer died and I have no way of getting any charge to it. when I plug it in I get 3 flashing orange lights. please help!
i just received my X1C7 barely a week ago (Part Number: 20R10015US) and today, i tested using my X1C7 with the Thunderbolt 3 Dock Gen 2 (Part # 40AN0135US). unbelievably, even though my X1C7, like all X1C7 models, have TWO USB-C ports on the left edge of the laptop, only the 2nd USB-C port from the back was able to be connected AND charging the laptop!   plugging the USB-C/Thunderbolt 3 cable into the USB-C port closest to the back of the laptop (on the left edge) simply would not be charging my X1C7! may i ask if anyone has discovered the reason why this is happening?  one would think that both of these two USB-C ports on the left edge of the X1C7's left side would be equivalent! may i ask if anyone has discovered that the USB-C port closest to the back of the laptop (closet to the hinges) do not charge the laptop when connected to the Thunderbolt 3 Dock Gen 2? Thank you.
