New Intel HD4400 drivers for Lenovo Yoga 2 Pro?

Intel has new drivers for the HD4400 graphics chipset that's supposed to fix a bunch of issues and that's downloadable from Intel's website. Intel's update utility identifies the drivers as compatible with Yoga 2 Pro, but when attempting to install the installer aborts itself and tells the user to acquire the drivers from the "manufacturer", i.e. Lenovo.
When I check on the Lenovo site, however, there are only drivers dated October 2013.
In graphics driver age that's ancient.
So when is Lenovo allowing its Yoga 2 Pro users to update their HD4400 drivers, which in Oct 2013 were rather broken?
I'm talking about inadequate resolution scaling for the Yoga 2 Pro's high-res screen in some games, for instance, which is a pretty big issue to left unfixed. Meanwhile the Intel Update Manager that came with the Yoga 2 Pro's software bundle cannot, as of May 2014, even connect itself to the net to check for updates for whatever reason.

I was messing around with the power saving features with the Intel Software.
Y2P (Power profile is my own doing)
-CPU @ .7Ghz
-Brightness @ one button press below 50% on the slider bar
-CPU utilization 0-1%
-Keyboard led off
-Wifi on
Panel Self refresh off
Extended battery life for gaming off
Display power saving off
= 5,600 mWh
Panel Self refresh on
Extended battery life for gaming on
Display power saving on (slider to max battery)
= 4,600 mWh
I didn't get any screen flicker but I only had it on those settings for 10 or 15 minutes
As I am typing this post with one tab in Firefox open it is running at 6,600 mWh. Windows reporting 4:22 Hr and 52% battery remaining.

Trouble with Adobe Reader Touch on Lenovo Yoga Pro 2 in tablet mode. Pdf shows up as blank pages.

I have a Lenovo Yoga Pro 2 and when I change it to tablet mode and use the Adobe Reader Touch app, my pdf shows up as a blank page. I have installed other pdfs in the past and those show up fine. However, as of three days ago, whatever pdf I install shows up as blank on my screen. Is there a solution to fix this?

Could you please share your test file?

Read the Boot Camp Instructions, you have to download the drivers using Boot Camp Assistant
If you missed that I suggest that you read the instructions again.

Can't find drivers for Lenovo G50-30 for Windows 7 32-bit

Hi,
I can't find drivers for Windows 7x32 bit for my new Lenovo G50-30. Looks like Lenovo support doesn't have them. Am I wrong?

hi ziris,
Can you try these drivers:
Chipset:
Intel® Chipset Device Software (INF Update Utility)
Bluetooth:
Bluetooth Driver (Intel, Atheros, Realtek, Broadcom)
Camera:
(AVC, Bison) Camera Driver
If the above drivers doesn't fix the unknown device under Device Manager, can you follow this guide on how to install the drivers via their Hardware ID or you may want to consider installing Windows 7 64bit (this would be best if you'll be utilizing 4GB RAM and above).

How to update drivers for Lenovo IdeaCentre C560?

Hi all,
I have PC Lenovo IdeaCentre C560 with Windows 8.1.
There is installed LSC (Lenovo Solution Centre), which has "System" section and inside it is "Lenovo software update" block, where LSC advices me "Go to Lenovo's website to update the Lenovo software on your PC".
But there are thess problems:
There are 20 drivers for C560 for Windows 8.1 on Lenovo website.
Which of them I have to download and install?
I have tried at my Device Manager to verify for all of my devices to be last update (it was terrible work) and I always got information that my driver is up-to-date.
Somebody have told me that LSC is not SUITABLE for C560 machine.
So I have these questions:
Does anybody have installed LSC on his C560? A does it work fine (so it find and install always new driver) or he only get abstract ionformation Go to Lenovo's website to update the Lenovo software on your PC?
Are there other possibilities to regularly update drivers then LSC?
Thanks.
Solved!
Go to Solution.

Dragnote,
maybe it was caused my terrible English, so I will try to explain relevant aspects once again:
1) I bought my Lenovo IdeaCentre C560 (part number: 57322363) on 22th of May this year from "stone" shop, not through internet. The Web site of this shop is www.mironet.cz, but there is not my PC there in actual supply, because the shop stopped to sell this model. But the parameters etc of this model is on Mironet's Web site here:
http://www.mironet.cz/lenovo-ideacentre-c560-23quot-fhd-intel-core-i54570t-36ghz-8gb-1tb-dvdrw-nvidi...
but is is in Czech language.
2) My Windows are in Czech language, so I will translate it for you into English and therefore some informations/messages can be not fully exact. OK?
2) The LSC program was installed on my new PC with MS Windows 8.1 64-bit. I was only wanted to USE it! And why not. I got with PC only very slim User's Book, where was nothing much usable. And nothing about updating system and drivers, nothing about backuping etc. So I started to use SLC, because it was preinstalled there.
3) Problems of detect WHICH driver I have to update and HOW to do it:
3a) I tried three programs for detecting of my not-to-updated drivers: SLC, Detective and Smart Driver Update with these results: SLC only advice me to go to Lenovo website, Detective and Smart Driver Update gave me list of my not-to-update drivers, but the lists were rather different.
3a) The link I provided, http://forums.lenovo.com/t5/forums/replypage/board-id/ideaCentre/message-id/9220, lists 20 drivers and all of them were released in period between 16 Oct 2013 and 01 Dec 2013, so I have used abbreviation "end of last year", but you are right - mostly of them are from 16 Oct 2013.
3b) I TRIED to compare their date of released with drivers installed on my PC, but I have two basic problems:
3b.1) How to identify WHICH driver on my PC corresponds to drivers on Lenovo web site?
The names are NOT the same. For example: on Lenovo Web site is "Realtek Audio Driver V6695 for Microsoft Windows 8.1 (64-bit) - Desktop", released 17 Nov 2013, version: 6.0.1.6695. Then I found on my Device manager "Realtek High Definition Audio". So my question already is: "Is it the corresponding driver or not?". But let us say: it is.
So, now we can continue with next information on my driver : date of release is 15 Nov 2013, version: 6.0.1.7093. So I am not sure if these two drivers (one on Lenovo Web site, second on my PC) are the correct PAIR. There is antagonism between date of release and the version number.
3b.2) How to update, when I already "decided", that my driver is not-to-updated and therefore I need it to update?
I launch my Device manager, then I choice some driver, then I click on "to update driver software" and there display two possibilities: find driver on computer, or find driver on Internet. So I click on "Find driver on Internet". Then I wait about 10 seconds and then I ALWAYS get the SAME information: "The driver of this device is up-to-date"
This "optimistic" message I received for about 30 of my drivers. So there are three possible explanations how to explain it:
1) LSC, Detective and Smart Driver Update lie to me, when they tell me "You have some not-to-update drivers", because in reality all of my drivers ARE up-to-date.
2) I really have some not-to-update driver but because I cannot address correct WHICH driver is not to-up-date, I try wrong driver to update. Wrong, because it IS up-to-date.
3) I identify the correct not up-to-date driver but the choise "find driver on Internet" open finding of this procedure in non-Lenovo Web sites.
And maybe you are right when you write: "Sometimes, on a new system, Lenovo installs drivers that are "newer" than the drivers listed on their site. Don't worry, keep the newer drivers."
I apologize very much,but I am not able directly to use the information from you.
I never updated drivers on my old PC (I had it 12 years!), so I have no experiences what happens when I replace my NEW (up-to-date) driver with some OLD driver installed from Lenovo Web site. I am affraid that my keyboard, mouse, screen etc will stop its function.
When I bought this Lenovo machine, I to myself have told that I will keep my drivers up-to-date, but I do not how.

[REQUEST] rtl8723au_bt bluetooth driver for lenovo yoga 13

Hello.
I have a lenovo yoga 13 laptop with 8723 wireless card.
Wifi is working bacause of dkms-8723au-git package. As I know, in 3.15 kernel it will work out of the box and lwfinger will no longer maintain this source code.
Bluetooth is not working and there is no bluetooth driver in aur. It is required to install another package from here https://github.com/lwfinger/rtl8723au_bt.
I cannot build this package, because when I run make command it ends with error make[1]: *** /lib/modules/3.14.4-1-ARCH/build: No such file or directory. Also there was written about no dkms support in code. But I cannot fix it, because I am still noob in Archlinux. And for some reason it is written "Support kernel version 2.6.32~3.13.0" in readme.txt. I have already 3.14.4-1-ARCH kernel.
Could anyone help me to fix that and make aur package for other people to get bluetooth work on lenovo yoga 13?

I think bluez5 is ok, because when I run bluetoothctl it can detect my cluetooth controller now. However, I cannot start working with it

Photosmart 6520 64bit drivers for windows xp pro

Can't turn up any drivers for my new 6520 on my older XP PRO 64 bit system...
Any help out there ?

Hey RichardChambers,
Thank you for your question!
Here's a link to the Driver page for the Photosmart 6520 e All-In-One for Windows XP
A common question is, "should I get the Full Feature driver or the Basic driver?" The best answer to that is try the Basic, first if you want. Then, if you find yourself wanting more features, download the Full Feature driver.
Let me know if you've got any other questions on that

Question about modifying the boot order for Lenovo Yoga

I created a bootable USB for crash recovery. How do I configure the Lenovo Yoga 2 Pro boot order so that it boots from USB first? Is there some function key I need to press while the laptop is booting up to get some kind of boot screen?
Solved!
Go to Solution.

I had used the "Create a recovery drive" option. You find this tool by pressing the windows key and typing in recovery drive, and clicking on the Settings category. This launches the Create a recovery drive application. This tool apparently copies over the recovery partition from the hard drive. Thanks a lot for your help. I will try to press the button on top of the power button and see if I can set it up to boot from the recovery usb drive.

Latest Release 265 Series Nvidia Drivers for Lenovo T61p?

I ran 3DMark06 this evening on my T9300 T61p and got my usual 4460 Benchmark Score .... however, the benchmark's results page today lists a newer Nvidia Quadro FX notebook series driver available for my WinXP 32-bit system directly from Nvidia.
At the Nvidia site it looks like it's Nvidia's Verde Notebook Release 265 Series v266.58 WQHL Certified display driver, released in January 2011, which claims support for notebooks using Quardro FX 570M graphics.
The Nvidia download site is found here:
http://www.nvidia.com/Download/index.aspx
I selected from the Nvidia Menu:
Quadro , then
Quadro FX Series (notebooks) , then
Quardro FX 570M , then
Quardro Graphics Driver , (from a choice of 5 different drivers for different scenarios), then
Windows XP , then
English , then
Search
Anyone tried this driver setup yet?
Two (I used to have Five) - T61p 15.4" WS T9300 2.5Ghz units, August 08/08 Builds with FX570M Nvidia Graphics; ... One W520 i7-2860QM w/2000M Nvidia Graphics (most recent acquisition and stupidly fast); .... One - T42 4:3 15" Flexview 1.8GHz with ATI Graphics (still perfect for traveling); ... Two - T500 15.4" units both with ATI HD3650 Graphics.

My advice is proceed with caution. Latest drivers aren't always the best option. I'd also read the release notes and see what was done to them. Driver updates are often issued for non-issues and won't make any difference. Here is an example of a ficticous update reason.
Bugfix: driver cause BSOD crash on dell XPS model XXX to YYY when entering hibernation
Such an update would never be picked up by Lenovo because it won't matter to any lenovo computer, and if you constantly update to the latest drivers, you're not avoiding problems, your making yourself little more then a beta tester running new code that could turn out to be unstable.
My motto is... if it's not broke, don't fix it!!!

New updated ATI drivers for MBP

Hi!
I would like to know where I could find new drivers for the ATI chip? When I play Half Life 2 the system asks for updated drivers, but when I look around at www.ati.com/drivers I can´t find any drivers that fit my system....
They have a support site for ATI Mobility Radeon, but they don´t support Apple..
Does anyone know how to find the latest drivers?
MacBook Pro 15 2,16Ghz Windows XP

If you want a tiny bit better preformance, though more for the fact of better stability and the possibility to overclock it to the 'proper' clocks, i suggest the omega drivers. www.omegadrivers.net - simple, and easy to install. They are the latest catalysts also from when i last checked. They also wont give you a hassle if you overclock teh card, unlike teh apple ati ones
good luck!

GD85 and New Intel SATA drivers

Intel updated thier SATA drivers for RAID so that TRIM will work correctly.
Does one of you experts know if the new Intel drivers are included in BIOS update
V1.3 07/12/2010??
Pat

Guys, I misspoke, I am not talking about the BIOS, I am talking about the Intel SATARaid drivers listed on the download website with a date of 01 2010. These are the Rapid Storage Technology drivers. I know that Intel released a new Rapid Storage Technology driver to solve a problem with TRIM when the Intel SATARAID technology is used in a RAID
mode. Basically TRIM wont work on a RAID array because of a problem in the Intel driver.
I am wondering is the 01-10 version on the download site includes the new fix.
If it doesnt can I use the Intel driver from the Intel website
