Lenovo B / G Series :: B590 - Switchable Graphics GF GT720M Disabled In Device Manager

Feb 7, 2014

I've bought a B590 and installed a Win 7 64bit. I have installed all available drivers from the support page and have the following issue:
 
Device Manager:
I see 2 graphics devices
Intel HD Graphics
NVIDIA GeForce GT 720M

The discrete card is disabled with error code 43 and has an exclamation mark near it [URL] .... Moreover, if i start the NVidia Control Panel it gives me an error with text: "current display is not connected to nvidia GP" GeFoerce Experience is not starting with a back-end error [URL] ...
 
Now here are the ways i tried to use but it did not work:
1. Enable high performance and update with manually downloaded nvidia driver
2. Do the same with HDMI cble connected to a plasma
3. Disable enable the device (screen goes black, than to normal and everything stays the same)
4. Format c: reinstall Win8.1 64 and install all drivers - same thing 
5. Format c: reinstall Win7 64  and install the graphics drivers after everything else (h1d9d9.exe h2d903.exe)
6. Update GT720M drivers  from device manager  (driver is up to date)
7. Run a high-performance 3D game (War Thunder)  - it uses Intel HD
 
What else can i do? I saw people with switchable graphics use some kind of application to specify the game-apps that should use a discrete videocard. I don't have such an app to specify my games.

Lenovo B590 B / G Series :: When Try To Check Sound Device Window Pops Up - Device Is Already In Use By Another Application

Jul 20, 2014

Faced with the problem. No sound after the laptop. When you try to check the sound device, a window pops up "the device is already in use by another application." But no program is not running. After rebooting the laptop sound occurs. Drivers are all set.

Audio device Realtek ALC269
Win 7 Pro SP1 (x64) with all updates
Motherboard 20208
Chipset Intel Panther Point HM77
BIOS Version H5ET84WW(1.22) (11/26/2013)

UEFI boot mode, not Legacy.Drivers for sound downloaded from realtek.com.tw. With standard windows drivers sound is always there. Tried the previous version of the drivers - ineffectually. Could it be that the problem is due to the UEFI boot mode? I do not want to reinstall the OS mode Legacy just to check it out.

Lenovo ThinkPad W Series :: Unknown Device In Device Manager After Win 8.1 Upgrade On W540

Aug 29, 2014

I'm using the W540 with an ultradock and external monitors. After upgrading my W540 to win8.1 64 bit, device manager is showing an unknown device. I'm not quite sure what it is, but almost everything seems to be working fine and Lenovo solution center isn't finding any driver updates.
 
I did notice that the solution center hardware scan did not test the video card memory and listed that test as N/A. Video and monitors seem to be working fine though and both nvidia and intel graphics show up in device manager.
 
Device manager lists the device in question as follows:
Device instance path: ROOTSYSTEM001
Hardware Ids: rootiwdbus
Device stack: DriverPnPManager

Lenovo P/Y/Z Series :: Y560 ATi / AMD Driver Not Installing Properly / Card Not Visible In Device Manager

Feb 5, 2014

I have a Lenovo IdeaPad Y560 which had both Intel and AMD drivers installed correctly, switchable graphics was also functioning properly.
 
The problem started when I tried to update the 2010 AMD driver with the latest one (2011) on the officail Lenovo site. The install seemed to run through, but informed me that there were warnings during the installation. I opened the linked log file, but it did not include any errors or warnings, only that the installation ran through successfully.
 
As the driver version still showed that it was the 2010 driver which is installed, I uninstalled the driver, and tried to install the 2011 driver again after a reboot. It once again said that the installation was successfull, but with warnings (still no warning in the log file). When I tried to check the driver version, it turned out that the AMD graphics card is not visible in the device manager, not even as an unrecognised device.
 
I then tried to install the old 2010 driver (the original driver installation files were already on my D: drive upon delivery), but got the same results as with the 2011 driver.
 
Removing any AMD/ATi related programs did not work either, I still get a "finished" installation with warnings, and a log file without warnings or errors.
 
OS is Windows 7 (64bit)

GPU: ATI Mobility Radeon HD 5730 (+Intel HD...)

Switchable graphics is turned on in BIOS.
 
how I could get the system to recognise the attached ATi graphics card, or at least realize that it is there?

Acer :: Timeline TG Series With HD 4330 Switchable Graphics

Feb 20, 2010

enormous potentials of the Acer timeline series that have switchable graphics enabled.

Doing Google search,as well as NBR's own review doesn't show up much information with regards to the switchability side of the Laptop.

For those concerned, any timeline series with a TG, have the HD4330 in it I think?

Dell Inspiron 7520 :: AMD Switchable Graphics Stuck On Intel HD Graphics 4000

Apr 4, 2013

I have an InspironR Special Edition 7520 and my AMD 7760 2GB will not activate or do any graphics processing. It is stuck on the Intel Graphics. I am running windows 8.

-My laptop is set on high performance and is plugged in.

-I ran NovaBench and it used the intel graphics card

-FurMark detected Intelgraphics as my main graphics card

-I ran a small game called "Slender: The Arrival" on the lowest settings it could barely handle it

-During the game and the graphics run I had Catalyst Control Center Up and it showed 0% usage of the graphics card, indicating it failed to switch

- All the drivers are up to date, per the windows solution and from downloading them from the AMD website.

I would like a solution to either, have the switch start working, or to change a setting so only the graphics card is constantly used. If this does not work I fear I'll have to return the laptop for faulty hardware.

Lenovo B590 B / G Series :: Won't Boot From USB Key

Sep 10, 2013

I've just bought this laptop, and it came with windows 8 preinstalled, and I'm trying to install Windows 7 on it.
 
I have a bootable usb, which I've used many times to install Windows on my other laptops, but the B590 just wont do it. I feel like I've tried everything. I changed the boot priority order in BIOS with USB HDD as number 1 but it still just boots into windows 8.

I've tried removing everything but USB devices from the boot order, and now I get this boot menu: [URL]

Which is exactly what I want to boot from, but when I press enter to boot from the USB device, nothing happens.

The USB device IS bootable with a primary partition. I've used these steps to make it bootable in DISKPART [URL]

After having no luck on the B590, I tried booting on the USB on a different computer, and it works perfectly well. Starts installing windows 7. So it seems like the problem is not with my usb device.

I even tried restoring the USB drive and using Lenovo Bootable Generator application to make the usb bootable, with the same result.

Lenovo B590 B / G Series :: RAM Upgrade Is Not Being Detected

Oct 2, 2014

Yesterday, I bought a Kingston 4GB PC3-12800 CL11 204 Pin SODIMM RAM chip from my local hardware store because I wanted to upgrade my Lenovo B590 memory, which - by default - has 4GB of DDR3 RAM installed. I had already double checked if the memory was compatible with my B590 by calling Lenovo Support and searching the web (yielding this post, for example). Both sources confirmed upgrading should not be a problem if I did not exceed the 8GB limit. However, after I had hooked up the RAM, I found that it was not being recognized by both my OS (Windows) and my BIOS. They are still indicating that I only have the factory 4096MB installed.How can I make my system utilize this RAM upgrade?
 
When I was determining which RAM to buy, I did also check what kind of memory was already installed in my B590 by the manufacturer. I unscrewed my notebook and found one memory chip, brand Hynix, of which I assumed it was one chip of 4GB. However, results for looking up its serial on the web show that it is actually one 2GB DDR3 SDRAM chip. I checked my hardware but could not see any other chip (although I am 100% sure my system has 4 GB RAM installed by the manufacturer).

Jul 22, 2014

My fan is not working properly, in fact it only runs for few seconds at booting and then never again.

My cores get about 70°C and higher (with only Skype and Chrome on), so I'm forced to use external fan to by able to work.

I found this problem when I was working and then my notebook suddenly shutdown a I wasn't able to turn it on for a while. Then I grabed it and I almost get 3rd degree burns. 

Two noisy external fans, that I have to use to keep core under 70°....

For about week I have problems with sound device, so that no sound is played. When I start my notebook it works few minutes, then it stops and when I wanna to test it it gives me error message:

"The device is being used by another application. Please close any devices that are playing audio to this device and then try again.", even when I have no programs running.

Lenovo B590 B / G Series :: MSATA Does Not Show In Bios?

Sep 7, 2014

I am using a B590 booting from a mSATA SSD (Mushkin). I am booting in to Ubuntu 12.04. Everything worked fine for half a year. Last week booting from the SSD did not work any more. Now the mSATA SSD is not visible in my BIOS, under Windows 7 oder several Linux distros. I cannot access the mSATA SSD at all. I am especially surprised that my configuration quit working from one day to the other without any action from my side. The usual set of questions:
 
Is there something trivial that I do wrong?Is there a way to check the sanity of the drive and/or my notebook?Is there any way to revert to the previous extremely satisfying state?My BIOS-version is 1.18 (06/27/2013).

Sony :: Switchable Graphics For All I5, I3, Some I7

Feb 9, 2010

Read up on the new Nvidia optimus tech
[url]

From the looks of it, it will support any pc running windows 7, a 200m or 300m 40nm Nvidia gpu, and an IGP.

Their new driver scheme allows both GPUs to be used on a per application basis. The discrete GPU can power down completely when using apps that don't need its power, and power up in 300ms when you start an app that needs it.

Best part is, no more relying on sony to package new drivers or hacking them together for you Z series guys. It is supposed to let you independently update drivers for each GPU.

For other models, this looks like it will enable switchable graphics provided we can get the IGP enabled in BIOS. So the challenge now is to find the offset for the IGP like people did for the VT hacks.

I'd be interested to see some of the Z owners install the optimus drivers and see what happens since they already have an enabled IGP.

Lenovo T400 / T500 :: T431s - Code 28 In Device Manager For All External Storage

Nov 28, 2014

I'm using Windows 8.1 on a t431s. I'm having this problem where none of my external storage is being recognized. Under "Device Manager" any sort of external storage I plug in ends up under "Other devices". When I click on the device, I get Code 28 "The drivers for this device are not installed." Trying to update the driver brings me nowhere. The devices don't appear under disk management.
 
What's weird is that other USB peripherals such as mice and USB headphones don't have any problem. 
 
Here's what I've tried so far: 

Updated the BIOS.
Used Lenovo's SCCM package for Windows 8.1
Tried installing the individual drivers for each hard drive.

Nothing works!
