Lenovo T400 Memory Slots

Maximum Memory: 4GB: Memory Slots: 2 (2 banks of 1) non-removable base memory: 0MB: Machine name: Lenovo-IBM ThinkPad T400 CPU options: Intel Core 2 Duo P8400 (2.26GHz) Chipset: Mobile Intel GM45 Express Chipset HD Bus: Serial ATA Front Side Bus options: Memory Speed options: PC3-8500 DDR3-1066 204pin SDRAM SODIMM.

Lenovo T440s RAM: What You Need. The Lenovo ThinkPad T440s has 4GB soldered onto the motherboard and an additional SODIMM slot, which is either empty (if you bought with 4GB) or has a chip in it. The T450 has 2 memory slots; the T450s has a single slot with 4GB soldered. In general, 5th generation machines will support the 16GB DIMMs now available. They are expensive, but they do allow more expansion. This implies a max of 20GB on T450s and 32GB on T450.

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

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 :: T520 SD Card Reader Not Detectable After Windows 8.1 Upgrade?

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 :: Can Memory From T520 Be Used On T430u

I got a T520 with 8G memory, beer accidently spilled on it, it wouldn't start again. So I got a new T430u with 4G memory. I was wondering if I could take the 8 G memory from t520, to be installed on t430u, is it gonna compatible on t430u?

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

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

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

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?

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 :: ThinkPad T520 RAM Clock Speed Stuck At 1333?

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 :: Arrow Keys For Scrolling Not Working In Firefox On T520

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

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 :: ThinkPad T520 Headphone Jack On Docking Station

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 :: Huge Slowdown On T520 After Updating Through TV System Update

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 :: ThinkPad T520 - How To Reduce Screen Brightness Below Standard Level

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

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

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

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 :: SIM Card Not Recognised In T431s

I inserted a mobile broadband SIM card into the slot of my T431s, as described in the user manual. The SIM Card (EE 4G) works fine in my Huawei Mobile Wifi E589.
The Laptop is installed with WIN7 64bit Professional and all WIN7 updates are installed. I gave the laptop to our IT department, who called Lenovo Helpdesk and we got the reply that they can give us a brand new image of the harddisk which MAY fix it. Our IT department as well as myself tried everything including the obvious such as access connections. The WIFI module in access connections is greyed out. It seems that the SIM Card is not recognised. We tried also SIM cards from different providers, which do not work.
Having just spent some time installing my programmes and files, I am reluctant to have the whole laptop wiped and re-imaged....

I've looked at the bios options and can't see anything obvious that should be changed.

The I installed Lenovo System Update and all its recommended updates and did a new system file check, Windows system files corrupt. What Lenovo update is destroying the system?
