Lenovo Yoga 2 ProFlex :: Laggy / Choppy Scrolling When Reading EBooks And PDF Files
Sep 12, 2014
I just got the Lenovo Yoga 2 Pro 13.3" Touchscreen Ultrabook - (Intel Core i5-4210U) last week. I need it for college, mostly for reading ebooks and PDF files... but also for HTML coding, photoshop, illustrator, and after effects.Â
Â
However, I am having lagging problems when reading ebooks, and PDF files (on Adobe Reader). When I scroll the scrolling is choppy, slow and laggy. Is there a way to make the scrolling smoother? This problem happens both in tablet and laptop mode. The scrolling is fine when I'm on the internet or using another software, it mostly happens on PDF files and ebooks.Â
Â
Just to clarify the lag/choppy scrolling happens BOTH when using the trackpad and when using the touchscrean display. When I open a PDF it is automatically choppy and laggy.Â

How can you do it? I find 'natural' scrolling extremely irritating.

Just picked up my brand new Yoga 3 Pro a few days ago and on the whole I love it, except I've just noticed there's an odd issue when listening to music (whether it be local or streaming thru spotify).
Â
If I'm browsing a document in Word or even when accessing the Lenovo Support screen from the Start menu, any left to right horizontal scrolling (either with the touch screen or touchpad) causes a crackling interference to the sound. I did notice it would crackle as the Discussion forum cards were loading up and appearing too.Â
Â
It's not the physical speakers themselves because this occurs thru headphones as well.Â
Â
Strange thing is it doesn't occur when scrolling vertically through a document.Â
Â
On the whole it's not a HUGE problem, but given it's a brand new 2grand laptop, now while it's still brand new and I haven't even had a chance to load much onto it. How to stop this from happening?

I bought this laptop G500 Lenovo 4 months ago and I am satisfy but unfortunately I found out still it have defects my problem is my cd/dvd rom I got un annoying noisy sound inside when I put a cd on it I guess it will give me problem sooner and now it happens it won't read anymore. I try to search for answers maybe it only a software issue but doesn't work any trial. Uninstall driver and bring it back don't work still there is the annoying sound and not reading. I guess a mechanical failure in its cd alignment that it is spinning but the head is keep on adjusting which creating the noisy sound means it was not align to read the CD.

Now that the new MBPs have arrived, they come with a new feature called inertial scrolling (like flick-scrolling on the iPhone).
Is this feature specifically hardware dependent or could this feature be implemented into the OS via a application like Bettertouchtools?
Are there any apps out there right now that has this feature?

I have a user with a 68855TU. Using Windows 7 64 bit.
When running dual screens and connecting to the Terminal server with Dual screen, dragging the mouse cursor to the top of the laptop screen the image on both screens will move a couple of inches.
Â
Solutions tried so far:
-Tried lowering resolution of the screens on the client side. Issue still happened.
-Checked the driver driver. Going through Screen Resolution -> Advanced Settings, under one of the tabs there was a check box for "auto scroll function". Tried with and without this checkmark with no change. Left it off, the way I found it.
-In the RDP software, checked the "Use all my monitors for the remote session" (It was off, but all screens seemed to be getting used). Scrolling still happened. Turned this off. Only only monitor got the connection, and no scrolling.
-Also tried changing the display config down a step in the RDP connection. Given the laptop screen size and no scrolling happened with that setup.
-Tried using only laptop screen. No Scrolling.
-Tried using only the external screen. No scrolling.
-Used the Lenovo software to check for driver updates. None found.
-Downloaded the latest driver from Lenovo. Driver from April this year. Updated the computer. Reboot. Scrolling still happens.
-Tried to install the latest Intel drivers for the video chipset. Get the message that it has not yet been approved for use by manufacturer.

I have bought g500 and configured the mouse settings following a post for the same problem in the forum.
It was working for the first time, but after i used external mouse , then it is not working anymore. It is not handy to always take mouse with me.
(This is the screenshot for touchpad configuration on my laptop)Â

So since I've bought this computer I've had problems with the two-finger scrolling suddenly stopping, like many people have. That's always been fixable by going into properties, device settings, settings, unchecking/rechecking one of the boxes under "two finger scrolling" and hitting OK.
Â
Now, though, my touchpad is suddenly stuck on one finger scrolling, and it's super annoying. There is no "one finger scrolling" option under the "scrolling" drop down thingy under device settings, so I haven't a clue why this is happening. I've tried the usual fix above, restarting the computer, installing new drivers, but it still does one finger scrolling. Which means it scrolls a lot of the time when I don't want it to, and the pointer seems to get "stuck" at times when I'm just trying to move it around.

I always liked to use the arrow keys on the bottom right of the keyboard for scrolling down pages as I read long documents. For some reason this is not working in Firefox on my T520. What setting I can change to enable this?

I recently purchased an HP HDX 18T Laptop with the QX9300 CPU, 4 gigs of RAM 1TB HDD's and the 1 GB 9600m GT video card. I have noticed that when maximizing and minimizing windows they tend to be a bit slow at times. Also, scrolling through websites can be very slow as well. Very laggy. I am running Vista x64 Ultimate, and I have the LaptopVideo2Go drivers, version 179.67. I have gone through hours upon hours of different video drivers, both stock and modded to see if that is where the problem lies. Many of the video drivers provide weird articats, and cause blue screens to occur. I have found very few stable, and relatilively functioning drivers. Gaming doesnt seem to be too bad, aside from the card not performing as well as I would like, especially in Fall out 3. I have the resolution set at 1920x1080, AA off, and the rest of the settings at high. I was hoping for a bit better, but this isnt a 130m card.

I'm experiencing a really weird UltraNav behavior on my new refub T410 2537-XH4 (2537-DB5 before refub).
Â
Step 1: I go into Control Panel -> Mouse -> Wheel tab -> Vertical Scholling -> select "One screen at a time" -> click "OK" button.
Step 2: I open a long web page and use UltraNav to scroll up or down.
Then, I go back to the Mouse setting in Step 1 and now the setting in Wheel tab is reset back to scroll one line at a time. I repeated this many times and as soon as I use UltraNav, it resets it back.
Â
I have Windows 7 Ultimate 64 bit, ThinkAdvantage System Update v4 and with all the latest drivers.

I just got a CTO Z590 2.4 GHZ, 3 GB ram, Vista Business "Fresh Start". I'm getting a feel for its performance.
When I attempt to play a HD video with my from within IE, Chrome, Firefox, or quicktime at full screen the video is choppy, less than 10fps. I've got the newest versions of webbrowers, flash, and quicktime.
Here are some examples:

I've let the videos buffer so internet connection isn't an issue, and I'm in "speed" mode.
I'm upgrading from 6 year old 1.4Ghz Athlon, so I had expected the Z590 wouldn't have a problem, am I expecting too much?
Do others have an issue with these videos?
Should I make use of my XP downgrade disk?

The trackpoint middle scrolling button doesn't work for some of the newer applications such as ITunes, the newest versions of Picasa, Windows Live Mail, Safari, and Windows Live Writer.
Below is a fix applicable to all Windows OS's. The location of the edited file may vary so look in the Device Manager under trackpoint driver details to find driver locations.
The file must be edited as an administrator in Vista and Windows 7. To do this, at the programs box type in notepad and on the notpad program in the menu right click and select, "Run as Administrator."
In Win7 x64 it is located at: (edit with Notepad run as Administrator).

My MDP to Hdmi arrived today and works great on my Dell 24" however my Logitech Nano mouse would randomly become laggy like its losing signal causing the mouse pointer becomes jerky. Once I unplug the MDP the mouse works fine again.

So as the title indicates, i get choppy video when i try to watch some sort of online stream such as youtube or hulu in full screen view.
It's unbarebly choppy, just not as smooth as it could be.
Does anyone know how to fix this? Fullscreen viewing works fine on my XPS desktop (4 years old), so i dont think its the internet

I recently used my recovery disks to go from XP back to Vista after a very dismal Xp performance. My download speed is now around 40 kb/s from HP.com (for drivers), firefox set up download 45 kb/s? Also i've noticed that video's online buffer at an alarmingly slow rate. I have Cox high speed internet and it used to be around 400-600kb/s and pretty quick buffering. What the heck happened? And why did my graphics score drop .2 points?

My sons laptop has died and needs returned for warranty work - likely a problem with the mother board.  It was suggested that we backup files on the hard drive before sending. I pulled the hard drive and attached it to another computer via Serial ATA to USB cable.  A portion of the hard drive can be accessed through Windows Explorer which shows 25GB of the 750GB hard drive and only shows an applications and a drivers folder.  Word documents, data and pictures cannot be found.Â
Â
I tried to take ownership of the hard drive thinking that this might make the data visible but it did not. I expect there is about 150GB of file storage (excluding programs) that we would like to back-up. Am concerned that the hard drive may have been damaged but the data that is accessible seems to be whole and intact.  Â

I'm having a Dell XPS L321X and the trackpad is totally laggy compared to a macbook. I'm using Win8 and installed the win8 driver and the two finger scroll has a delay of half a second.
I tried the newer Win7 Cypress Touchpad Drivers... the same laggy problem.
Any new drivers available?
Beside of that, i still have my fan problem: [URL] ....

I have a Dell Inspiron 8600 notebook. Win XP w/SP2. All recent updates + as far as I know, no virus or malware + latest Java and flash software + latest Nvidia GoForce 5200 driver
Problem: Video playback in flash players like www.dailymotion.com is choppy when notebook is running on battery. The same video playback is perfect when I connect the external power supply.

I just bought an Acer Timeline 1810TZ a few days ago. I'm having problems with video flickering when I play .avi files and every other file format in VLC media player, I tried a few other players and it's the same issue. I'm pretty sure it's the video drivers I'm using but I don't know how to fix it. I did a clean install of Windows 7 ultimate the day I got it. The image and audio speed is fine on the screen but there's flickering lines across the screen when the camera moves around.
it's not fun watching flickering movies.
I have installed the Mobile Intel® GS45 Express Chipset drivers just as recommended on this forum Acer 1410, 1810, 3810, 4810, 5810 Timeline Drivers, Software, Tweaks and Settings FAQ
Here a screenshot:

problems with video playback on any site that uses flash as their means of delivering video content.
Some examples of sites are youtube, HULU, and abc.com
everytime i go into full screen mode the video becomes choppy, delayed and just unbearable to watch.
I have a geforce 9200m gs with 512 mb of vram running at 1920x1200, a core 2 duo 2.0ghz HP dv4t running vista x64 (though i had problems with both windows 7 beta and vista x86) and i have the latest nvidia drivers and downloaded the latest flash software.
I have also tried multiple browsers (IE, firefox, chorme) and also tried both enabled and disabled hardware acceleration in the flash setting..

My inspiron E1505's dvd drive doesn't work anymore, i ran diagnostics at the boot screen to verify it.
So is it fixable without buying a new drive and if it isn't is it easy to install?
