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%.
Today I updated two Lenovo drivers (ACPI and Sound). After the installation I was asked to restart my Laptop. The restart did not finish and the system showed the bluescreen for a short time and the it restarted with the system recovery. All attempts to repair the system with Windows recovery were not successfull. I am still not able to start my Laptop.
My system is: Lenovo Thinkpad T530 (2429DT7) Windows 7 (64Bit)
I installed clean install windows 8.1 (iso directly from Microsoft) and I was thinking, that Lenovo System Update will install all necessary drivers and tools for me.Even newest bios wasn't offered for install. However, on lenovo's website all drivers was available.
System update Lenovo stopped working some days ago. Today I had my fingers crossed that maybe with the installation of currently latest version it will work (systemupdate506-11-04-2014.exe). When I have ran the installation it has warned me there are some previous versions and it will be installed, but installation didn't went thru. After manually removing System update service (sc delete SERVICENAME) and running the installation again, the installation wizard completed successfully...
But then when I run System update I receive an error "T440S - System update Cuuldn't start properly".
How to achieve that System update would work properly on T440s laptop. My operating system is 8.1 x64 enterprise.
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?
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.
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.
as i have learned there is no mechanical reason not to use classic keyboard-layout of the 7row model in a t530. but what are the effects of the bios no being able to support the 7r keyboard? which buttons will not work properly?
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?
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.

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?
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?
I always liked to use the arrow keys on the bottom right of the keyboard for scrolling down pages as I read long documents. For some reason this is not working in Firefox on my T520. What setting I can change to enable this?
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.
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?
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?
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.
I have tried to make a fresh Windows 7 installation, but after installing updates via Lenovo System Update the system gets corrupt.I replaced the hard drive on an T400 and loaded a image that I had on to the drive. After a installing a few updates and program I noticed strange system beaver. So I did a system file check and it came back that files was corrupt and cold not be repaired.So I did a new fresh Windows install. But it to became corrupt after just running Windows Update and Lenovo System Update.So I ran some hard drive and memory diagnostic without find and problems.
Then I did a new Windows 7 install again. After I installed all recommended updates from Windows Update I did a system file check, all OK. 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?
Just upgraded and installed the ASUS RT-AC68U router. Installation was smooth with no issue. I have the T440s laptop running Windows 8.1 with the "Intel Dual Band Wireless-AC 7260" adapter and I checked the device manager > wireless mode and still shows 6.802.11a/b/g. Should AC be included in this mode? How can I update the adapter to AC mode?
I want to upgrade my BIOS, but there is no update available for bios in windows 8.1.. My Bios version is 1.18, I want to update because i read somewhere that if your fan make noise make sure you have updated BIOS :A.. I want to know if I can install "BIOS update for win 8" in my lenovo t410 with windows 8.1..
On my Windows 7, APS works well with an icon on the system tray. But in Ubuntu (13.04), because of no driver, I dont know if APS works or not. The question is: does it still work silently without the driver on Ubuntu?If APS doesn't work, is my laptop harmed when it's shaken? Does Lenovo have any solution to get ASP worked on Linux (Ubuntu)?
This is a brand new T440s, i7, W7 Pro that I have had for 3 days. On the first power-up, the system date was set on "tomorrow," in other words, one day ahead. I reset the date, time, country and time zone. It is set to sync with the internet. Each morning now when I power it up, the system date is "yesterday," one day behind. I have to manually change the date each morning. How can I fix this permanently. Other than this date glitch, it's a beautiful machine.
I have a ThinkPad T431 with the 500GB HDD installed.tell me what the system drive is used for? When I go into the disk management view, I see 3 partitions: 1.46GB SYSTEM_DRV, 450GB for the OS and finally the 13GB Recovery partition.
Got a new T440 yesterday. Good machine, only a small issue with the Windows 7 System Restore feature that i'm not able to fix:
I wanted to try system restore but it did not work properly. There are numerous system restore points created but i'm not able to revert to one of these restore points. It says Local Disk (Unknown) - The station cannot be found. (Picture in Dutch)
After i received the T440, i created a new partition on the 256GB Samsung SSD. Maybe this is the reason system restore is not working properly?
I already fixed the mbr, but this makes no difference. In the picture below, you can see the partitions. I only reduced the size of the C: partition and created a new D: partition. The *SYSTEM_DRV, Q: Lenovo Recovery and the *: 7.00 GB partition are not changed at all.
System specs: Windows 7 SP1 x64 i7-4600U 256GB Samsung SSD 8,00GB Ram
I have previously done a system image of to T500 OS and everything. The T500 is on it's last leg. I received a T540P as a replacement but I want to migrate the T500 system Image to be restored on my T540P.
I know it's doable because I have done it BUT the problem is, I think the downloads. It seems when I go to update software after the image is done the T540P downloads. (the Lenovo PM, Graphics and Display drivers) when the reboot happens I get to the Startng Windows screen and the 4 bubbles coming together and then pulses. But it always says there. It at least, I stopped it after like a 30 minutes.
