Lenovo ThinkPad L R/SL :: L440 With Optimus - BIOS Option?
Sep 29, 2010
There are a few configurations of L440 laptops with Nvidia GT 720M grafic cards and Optimus (e. g. 20ASS01G00). Is it possible to change the used graphic system in the BIOS (Intel only/NVidia only/Optimus)? And which card is hardwired to the external ports (VGA, mDP)?
(Do this differ from the T440p or the Edge Series, E540?)
I have a Lenovo L440 laptop with a think pad pro dock. The HDD is encrypted with TrueCrypt and needs a password before windows will boot. The laptop will not display out to the monitor attached to the dock before windows loads. I have changed the bios setting Config > Display > Boot Display Device, as well as all the other display options, but it does not make a difference. I have tried with a VGA cable and a DVI cable and neither works. I have tried with 2 different L440s and 2 docking stations with the same problem occuring on both. I have successfully used a Lenovo L540 laptop with the same model of docking station. I have also updated to the most current bios version.
I'm wondering if I'm missing something or if the L440 model simply does not support this function?
1. Is it OK to add 8GB (so I will have 12GB in total) or it would be better to add 4GB in order to have two similar SODIMMs?
2. Are there any known incompatibilities for specific brands? I found two SODIMMs from Kingston (part numbers KVR16S11/8 and KVR16LS11/8) and one from Crucial (part number CT102464BF160B). All are clocked at 1600MHz.
W540 20BG001CGE, had BIOS 1.05 and RAID 1 with two Samsung 840 EVO 1TB working fine under Windows 7 - x64. Did a (by lenovo update tool recommended) BIOS Update with the bios update manager to 2.05. Update ran fine. After Rebooting (and loading defaults, disabling Intel Rapid Start, Changing BIOS boot option to legacy first ... I recognized SATA Option (AHCI or RAID) in BIOS is gone. At boot Intel Matrix Storage Configuration doesnot appear anymore (where you can build RAID etc).
Boot then brings up message "missing operating system".
Downgrade to BIOS 1.05 impossible, due to ISO File on www.lenovo.com support is not system compatible, message "Lenovo Group Limited - Invalid system disk; Replace te disk, and then press any key") (The link to the ISO File version 1.05 at the bottom of this page links a non bootable ISO image [URL]....) Also the downgrade to BIOS version 1.08 found here [URL] .... does not work, CD also messages "Lenovo Group Limited - Invalid system disk - Replace ...").
Rewriting BIOS version 2.05 (GNET57WW) does not work (says "BIOS update not necessary").

I have the Lenovo L440 (20AT002YGE) with the integrated Intel Graphics.
I have turned off the automatic dimming of the screen brightnes in the windows energy settings and also turned off the energy saver settings in the Intel driver but the screen keeps beeing dimmed when the background is black or dark. This is very annoying when you work outdoor and the sun keeps shining on your display and than it dimms the brightness.
I have L440 with 64-bit Win7. Earlier experienced major WiFi connection problems, which were fixed with BIOS and WiFi card driver update.
Briefly after that Wireless Radios Master Control no longer lists Mobile Broadband, it only shows 802.11 Wireless/Wimax and Bluetooth.
Windows Network Connections lists "Mobile Broadband Connection" as "Not connected, N5321 gw Mobile Broadband Driver. Diagnosing this connection suggests to "Turn on mobile broadband capability", which I cannot do as it is not listed in the Wireless Radios Master Control.
Customer has three L440 with Docking station PRO and Samsung 22" S22C45 on DVI
* W7 64BIT Sp1 Lenovo version not VL * Latest BIOS * Latest GFX Driver * All Windows WSUS Updates (Standard Image from lenovo with all Hotfixes) * Power Options set to Performance (lenovo Power manager deinstalled) * Office 2010 SP2, PDF24, APPV client 4.6+ * Dameware 6.X Agent
Laptop is in docking station with external 22" Samsung DVI and working in Winword, IE or others. Suddenly screen from Samsung turns black (laptop TFT from people who use dual stays on). After 1-10 seconds the samsung screen comes back. We fiest thought this was some RDP issue with other users connecting to the device. (Not the case)
NO > BIOS and GFX is latest and MADE it worser with updating to the latest (happens more often). NO > MHz change from 59/60 or slighty modify did not solve NO > It's not a screensaver problem NO > All three Samsung are from diffrent shippments and even Distributors NO > All three L440 are from different time periods 2-3 Months split
I have problem with wifi connection. Wifi works perfect with other devices: phones, tablets, laptops. When I connect to wifi with L440, wifi works 5-30 min. and then crash. L440 kills wifi network. All devices can't connect to wifi until I restart router.
I have read about this problem, but in task manager I can't find "discovery.exe" or LenovoEMC Storage Connector in Contral Panel.
I'm thinking of buying a Thinkpad E540 with a discrete nvidia gpu. I am planning to install linux on it and I don't really need optimus for it (nor is it well supported) but I'd like to occasionally be able to use it on windows.
I'd like to know if it's possible to completely turn off the nvidia gpu from the BIOS so it works only with the integrated intel one or should I buy one with intel gpu only.
I have read that the lenovo changed the dual gpu implementation on the latest generation thinkpads.
I was originally under the impression that my laptop (Thinkpad T510 4384-DS9) had NVIDIA Optimus display technology, however, I cannot find any OPTIMUS options in the BIOS under display (or any other section for that matter).
The reason I would like to know is that I have recently purchased a docking station (model: 4338) and 3 external monitors which I would like to use simultaneously.
Forgetting the fact that I'm using Linux, and that for most people this wouldn’t be a challenge worth undertaking, I would just like to know if my system actually supports 3 external monitors and the laptop screen concurrently using the docking station.
My IT dept made some changes to my W530 and now fastboot is not using SSD drive of (16G).I'm planning on using the "Restore" option found under My computer. If I select this option, I pressume all the factory default programs will install and wipe out the rest of the drive correct? If I do this will my fastboot be enabled once again?
I have a Lenovo Thinkpad X40 - 2371 that I would like to reset to its original Factory Settings. It does not have a CD-ROM drive so I can not use a Recovery CD. Its operating system is Windows XP Professional. I have tried to use the "Access IBM" and the "F11" buttons to see if I can find any Factory Restore option, but there is none.
We have new Thinkpad X240 laptops that don't have the ability to change the password using CTRL + ALT + DEL. They are using Windows 8.1. These laptops came with Windows 7 and we used the Lenovo media to install Windows 8. The ability to change the password was present right after the Windows 8 install but when we upgrade to Windows 8.1 from the Microsoft store we can no longer change the password.
I have a Thinkpad Twist and after updating the Lenovo Settings Dependency Package to 18.104.22.168, I no longer have the 'Automatically optimize for battery life' option in the Lenovo Settings app, i.e., the battery is always fully charged.
I would like to use the battery optimization option, how do I get this function back?
I got a thinkpad w530 with Windowd 8 from the factory and its ultrabay worked really well. I use a few SSDs in the ultrabay and used to swap through them by just ejecting the one currently in use and plugging in another one. However, since Wondows 8.1 update I haven.t been able to do so, as I have to turn off the machine and change the drives.
I believe it has something to do with the OS set up. How to enable the hot swapping capability of the ultrabay?

Its a y410p. I want to change my graphic to discrete graphic.
I have a Lenovo G480(Model 20156). My CPU is Intel Core i3 2370M. I have recently added another 1600 MHz RAM. But it is now showing 1333 MHz. I am using windows 8.1. Though I saw that some laptops can enable that by selecting XMP Profile on BIOS. But, my PCs Bios is not showing any option to select XMP profile or even any Advanced AI option.
My question is,
1. How can I resolve this problem and get my 1600 MHz RAM work fully? 2. How can I enable the XMP profile to get the full advantage of my 1600 MHz RAM?
I have a problem with my laptop Lenovo y570. I had a defective disk. After repair and return from warranty service, the Optimus switch on the right side of the notebook blocked or broken. I don't know. The computer used both graphics cards, but after installing the latest drivers works only integrated graphics. It seems that the Optimus switched, but I do not know how to switch it back when it is blocked. I tried install older driver and driver from recoverydisk for both GPU
I recently purchased my new notebook (Lenovo T440p) which comes with OPTIMUS integrated Intel graphic card coupled by GeForce GT 730M 1GB. I tried to play some games; however for some reason in game options show, that my Intel HD card is being used as a default graphic card. This suggests that OPTIMUS technology is not switching the graphic card properly. System running on windows 8.1 Pro 64bit. How to enable Optimus switching?
I have recently decided to upgrade my RAM from 2GB to 4GB. After installing, I booted up my computer to find that it would not recognize the new memory. After doing a bit of troubleshooting, I decided to try and update the BIOS, as the version was from 2010. I downloaded the BIOS update boot CD application from lenovo, burned a disc, and on reboot I found that the boot order did not have CD listed on it. Here's the catch: I don't have the supervisor password. This is a hand-me-down laptop, and I have tried to find the password to no avail. This is the current boot order: USB drive, Hard drive.
My question is, can I either create a BIOS update disc using a USB, or update the BIOS some other way?
I understand that it is impossible to recover the supervisor password without having it serviced (which I would rather not do, even if I have to send my RAM back to Crucial)
My system specs: Thinkpad L512 Bios version: 1.04 Bios date: 2010-3-26 Embeded Controller Version: 1.01 Windows 7 32 bit
I am unable to enter the BIOS (or the boot device and application menu) of my T530. When I press Enter at the 'Press Enter to interrupt normal startup' prompt, nothing happens. It just ignores my input completely. F1 doesn't do anything either.
Otherwise my ThinkPad is working fine, but I would like to change some settings (especially change the boot device, to boot from USB).
I am unable to update the BIOS on the Thinkpad listed below.I have tried to run Boot CD version of the update program (using CD player in dock) and it reports the error:"The system program file is not correct for this system"..The Windows based BIOS update program reports the error (in or out of dock):
"The process does not recognize this system. The process has been cancelled"..The Lenovo support page lists the new BIOS as being appropriate for this model. The BIOS reports the correct model and serial number.I desire to update the BIOS only as part of a software reload / refresh of the laptop. No actual problem with current BIOS to my knowledge.

I got a really annoying problem with my E330. It came without an OS, so I put Win 8 on the preinstalled HDD. Then I switched it out for a SSD and put Win 7 on it. (everything in UEFI mode)
Since then I can't get into the BIOS/UEFI anymore by either pressing Enter or F1. Pressing Enter still gives me a beep, but then Windows continues to load normally instead of showing several options like it used to do.
And yes I'm aware that I need a cold-boot in Win 8 to get into UEFI ... The only way to access UEFI at the moment is through the Win 8 charms-bar restart into UEFI trick.
I tried already to reflash the BIOS which doesnt work obviously since it's the same version, tried removing the CMOS battery, that gave me a one time opportunity to get into the UEFI with F1 when it complained about the date/time.
Switching to Legacy only leads me to an infinite PXE - something error loop, but I still cant get into the BIOS.
I tried pressing every combination of Fn+F-Keys and without Fn. Nothing works. I don't want to return the notebook, but it's a deal breaker for me if I can't get Win 7 running on it with accessible UEFI.
