Dec 10, 2012

How to reduce screen brightness below standard level in ThinkPad T520 ?

I think it is possible somehow, but I don't know how. I reduced brightness to zero using Fn key + End key, but it's not enough, I want to make screen darker, because my eyes get tired.

Lenovo T400 / T500 :: ThinkPad T520 RAM Clock Speed Stuck At 1333?

Jun 7, 2014

I'm having trouble figuring out why on my T520, after upgrading from 8GB/1333Mhz to 16GB/1600Mhz Crucial RAM, Speccy/CPU-Z still says they're running at around ~660Mhz x 2 = ~1330?
My specs are as follows:
For my T520 (4239-CTO) I have...
Processor: Intel Core i7-2860QM 2.5Ghz
RAM: Crucial 16GB (8GB x 2) DDR3-1600
GPU: Intel HD 3000 / NVIDIA QUADRO NVS 4200M
OS: Windows 7 Ultimate x64 SP1 (w/latest updates)
After Googling for a while and from looking around here I've read nothing that says I shouldn't be able to run at 1600Mhz especially considering my processor supports that speed officially. Another post on this topic (not for the T520 specifically) mentioned that i7's contain the memory controller within itself. So... am I being thwarted by software settings in the BIOS or within my operating system?

Lenovo T400 / T500 :: ThinkPad T520 Headphone Jack On Docking Station

Aug 7, 2012

I have a T520 thinkpad with a docking station.  I can get my headphones to work fine out of the laptop, but I would like to leave my headphones plugged into the headphone jack on the dock itself.  The computer doesn't seem to recognize this jack is even there.  My only sound options are the laptop speakers and the audio jack on the right side of the laptop.
How to enable the audio jack on the back of the dock?

Lenovo T400 / T500 :: ThinkPad T520 Reconnects To WiFi After Wake Up From Sleep But Web Pages Load Very Slowly

Oct 20, 2013

My Thinkpad T520, Windows 7 Pro takes over a minute to load any webpage  after waking from sleep. The wifi icon shows that the network has connected to the internet after about 10 seconds from wake up. But if I attempt to use a browser to load any webpage, I must wait nearly a minute before the page will load. After that, pages load quickly.
This problem occurs in multiple browsers (FF, IE, Chrome). I am using Intel Centrino Advanced N-6205 wireless adapter. I've updated the wireless driver and BIOS. I've cleaned out my registry using CCleaner, and I've defragmented.
One bit of advice I've read that I've tried from these forums does NOT work: Uncheck from Device Manager under the Power Management tab for my wireless adapater the option to Allow the Computer to Turn Off This Device to Save Power. Unchecking that option (which would seem to keep the driver on) makes the problem worse because the wifi will not reconnect at all.

Lenovo T400 / T500 :: No On Screen Display Of Caps Lock / Volume / Screen Brightness

May 27, 2014

I updated the BIOS to 2.26 a while ago and ever since then there's no on-screen indication of caps lock on/off, screen brightness or volume when I change it. Since it seemed to be affected by BIOS, I updated again to 2.27 just now, but the problem persists. I needed to update the Hotkeys Feature Integration by downloading the utility thingy from this page. Probably wasn't a BIOS thing after all.

Lenovo T400 / T500 :: T520 Crashes Once A Day After RAM Upgrade

Dec 8, 2014

My T520 (4242) never crashed until I upgraded the RAM. 
Initial config : Single stick of 4GB RAM.
  - FRU # 55Y3717
  - Samsung part # M471B5273CH0-CH9
Tried to upgrade with 2GB from following manufacturers:
  - Corsair CMSO2GX3M1A1333C9
  - A-data (don't remember the part #, but matching specs)
Result : Approximately once a day, I get BSOD. The system also crashes often while going in and out of sleep.
The A-data RAM works fine on a different laptop (T500), but I experience crashes when I put it in T520. This makes me wonder if my slot has an issue e.g. dust collected over time that causes a random read error. Or maybe I need to find the exact same part from Samsung to upgrade the RAM.
What else can I try? If it crashes randomly once a day, and works fine otherwise, can I conclude anything about RAM compatibility? memtest86 doesn't show any error.

Lenovo T400 / T500 :: Busted Sound On T520

Dec 26, 2014

Sound has busted on T520 for a few weeks now.  I can hear sound when I plug in my earphones, but windows recognizes this as a speaker, conexant 20672.   I checked the "find and fix audio playback problems" in windows 7 to no avail.  I believe I may have to have my speakers repaired.  I am still under base warranty until sometime next year.

Lenovo T400 / T500 :: SSD Slow Boot Windows 7 On T520

Jun 3, 2011

I have replaced  my old sata disk with a ssd disk . Intel 520 240 gb. on my  T520. I have a Windows 7 and a minor Linux partition. Dual boot. I have moved the old image  with Arconis True HD.
However, there is a HUGE difference in boot times between Windows  and Linux.
Windows is 1 min and 35 sec with windows logo until login screen appears. Then additional 20 seconds.

Linux is 7-10 seconds from Lenovo sign in bios until I'm ready to go. Off course I did not expect Windows to boot  as fast as Linux, but things has worsened after the change.
When Windows is up and running  the SSD disk is preforming in the same speedy way as under Linux. It is just the boot situation which is terrible. AHCI is enabled .

Lenovo T520 T400 / T500 :: 2nd HD Hard Drive Caddy Tray For SSD?

Nov 22, 2013

i want to use the DVD tray to add a 2nd hard drive using one of the many 2nd HD Hard Drive Caddy Trays i see online, but i want to use a solid state drive in it.  Can this be done? From what i ascertain via product literature, it appears that any caddy tray i see online says "accepts 2.5' 12.7MM SATA HDD only" or some such."  While there are many SSD's that are 2.5 inch, I've only seen ones that are either 7mm or "7mm (with 9.5mm adapter)."  Is there a product (either a T520-compatible 9.5mm caddy tray or a 12.77mm SSD) that can make this work?

Lenovo T400 / T500 :: T520 - BSOD Occurs When SD Card Inserted

Mar 8, 2012

I this will happen almost everytime if the machine has been in use for some time. Inserting an SD card (4GB Canon format) a BSOD is virtually guaranteed. After a new boot up it works fine but catastrophic if not since all info is lost and nothing is closed.
I looked at the dump file and the FASTFAT.SYS is the cause of the crash. This is a very old driver used in Windows 7 and there are numerous issues with it in many forums dating back even to XP. There are no crashes introduced by any other device or USB key/drive connected. Only the SD card.
I thought it may have be due to the USB controller being turned off for power conservation but even after removing the ability by toggling not to turn off to save power to the USB devices it still crashed the very next time I used it which was days later. The system was plugged in as well as it usually is.
I can do the same thing on my old notebook with its internal multicast reader running Window 7 32 bit and it does not have a problem. The Thinkpad does with Win 7 64bit. I am always conscious of a BSOD occurring if I dare plug in my camera card. This renders the port useless since I cannot afford regular crashes and a card reader externally may have to be used.

Lenovo T400 / T500 :: T440p Screen Slightly Adjusting Brightness On Google Chrome

Jun 24, 2014

My T440p slightly adjusts the screen brightness depending on what is being displayed. For example, on Chrome, one page might have more images, so the screen slightly adjusts brighter or darker. Another page it might slightly adjust again. And it does it when scrolling down a page as well. It is distracting, and I want to disable it? I'm on windows 7.

Lenovo T400 / T500 :: T520 SD Card Reader Not Detectable After Windows 8.1 Upgrade?

Nov 25, 2013

My SD card reader became non-functional after a recent upgrade of my T520 to Windows 8.1. Hardware troubleshooting said the Base System Device driver was not installed. I installed the Lenovo System Update software and searched for updates, but the driver was not updated. There is still a yellow warning symbol beside the Base System Device in the device manager. Discovered on the Lenovo driver download website that the card reader in my model is the Ricoh Media Card Reader but there is no driver compatible with Windows 8.1. Would the Windows 8 driver work or is there another solution to get my reader running again?

Lenovo T400 / T500 :: T520 - Flashing Lights On Power Up / No Post Bleep

Dec 11, 2014

I've been trying to set-up a second hand T520 bought without the original hard drive. I've installed a Samsung mSATA SSD. I tried to use a set of recovery discs produced on my T510 which seemed to install but got BSOD whenever Win 7 tried to boot.  I then downloaded the Win 7 ISO and booted from the DVD to try and initialise a repair which would not initialise.  I next tried installing Win 7 Pro from the Win7 ISO disc which succeeded but ran into problems with unrecognised network components and drivers. 

I've gone through this whole cycle again and got to the set-up screen for Win 7 then got distracted; my thinkpad then appeared to have gone into hibernation before I could finish set-up.  Unfortunately, when I try to power up I get a few flashing lights for a few seconds; no POST bleep and the power dies.  I've tried pulling and reinstalling the RAM and SSD but to no avail.

Lenovo T400 / T500 :: Huge Slowdown On T520 After Updating Through TV System Update

Mar 27, 2012

I recently updated a whole bunch of things on my T520, and afterwards experienced a significant slowdown in everything -- startup time as well as just general work. There's often a long lag when opening programs or documents, right clicking, etc. Part of this seems to be due to higher CPU usage. While idling (i.e. just sitting on my desktop) and looking at Task Manager, CPU usage seems higher than normal on some things -- SynTPEnh.exe will consume 3-8% of CPU, one instance of svchost.exe will take up to 10%, etc. My total idling CPU usage is generally 15-25% now. (I have a quad-core i7.) Also, my battery life dropped precipitously; it used to be upwards of 5 hours on a full charge when just doing general web browsing and word processing, but now it's less than 2 hours. 
Going around in Process Explorer and Task Manager, I've found a few things that seemed somewhat unusual: A lot of my processes have many page faults -- slightly under 15 minutes after starting up my computer, SynTPEnh.exe has about 250,000, SimpleTap.exe has over 50,000, the instance of svchost.exe with the Base Filtering Engine, Diagnostic Policy Services, and Windows Firewall has about 250,000, and Process Explorer itself has about 250,000. There were also some items that seemed like they might be taking up more memory (Private Bytes, in Process Explorer) than they should -- dwm.exe is using about 150 MB, and SimpleTap.exe is using about 115 MB. Also, my CPU percentage of Interrupts jumps around, most of the time staying between 2-5%.

Lenovo T400 / T500 :: T520 / Windows 7 - Suddenly Receiving Random BSOD And Applications Crashing

Apr 10, 2013

I've been running on a T520 4239-CTO for a little over a year now without issue.  I've been getting lots of random bsod and services crashing in the last few days; even Windows 7 cannot validate itself anymore.
I ran all the hardware checks in the provided Lenovo utilities and it all seems to pass.  I didn't trust this so I manually checked the smart values on the hard disk and noticed around 2400+ reallocated sectors so I decided to replace the hard disk.
It should be noted that there are no viruses/malware on this machine.  After receiving the new hard disk I did a factory restore using the dvd backups I made when I received the machine.  Upon booting the new factory install on the new disk I'm still getting the same random bsod and issues with Windows 7 not being able to validate.
I notice that everytime I boot now on the newly restored os that the "Microsoft Software Protection Platform" service has issues and cannot start.  I started doing some updates using the Thinkvantage tools and they're crashing too.
This machine is currently on pass 4 of memtest without any errors so far.
I've replaced the hard drive and from the looks of things so far the ram seems fine.  Where do I go from here?

Lenovo T400 / T500 :: T440 Freezes On ThinkPad Screen

Jul 2, 2014

This computer originally had an issue with the 2100 Detection Error. This computer was previously built with no issues when it was imaged with our company's Windows 8 configuration in which I am highly sure our IT engineers have worked closely with Lenovo on. Also out of the tens of thousand computers that were imaged this way this is the only system I have dealt with that has this issue. I luckily had a good T440 I could test this system's SSD in. The hard drive appears to be fine with no issues. So that rules out to be the SSD. I ordered a system board under warranty and installed it. Everything so far responded fine with the system board replacement until I performed the model type/serial number and UUID update using my 1.86 maintenance update USB thumb drive. After that completed the computer froze on the Thinkpad Logo screen. I verified again for my piece of mind that the memory module and SSD was fine. Sure enough those components were tested fine in a known working T440. So I submitted the system board as a DOA with an explanation. I received another system board to replace with the DOA. I installed that system board to once again update the Model Type/Serial Number and UUID using my USB maintenance disk 1.86 thumbdrive to once again end up with a locked computer at the Thinkpad Logo screen. I have replaced a couple of other T440 and T540 system boards during this time also with using the same USB maintenance disk thumbdrive used for updating those system's model type/serial number and UUID. So I know the issue is not with the USB thumb drive. I am very frustrated with this system. I hate to keep submitting DOAs for the same system.

Since the BIOS is part of the system board and I have not had these issues with the many T440 system boards I have replaced successfully that performing a BIOS update is not a good excuse why this doesn't work on this particular T440 and since after replacing a system board under "DOA" and updating with the maintenance disk and froze there is not a way I can run a BIOs update on this system now right?
