I've got a ThinkPad T520 and I just bought a Netgear N600 Dual-band Cable Modem Router but my laptop isn't seeing the 5GHz wireless network? Is it even capable of doing so?
View 7 RepliesI just got a new Thinkpad 540p but it can't consistently connect to my home wireless network. Since a day of getting it, it was able to connect on 3 separate occasions. One being the one during the initial set up which was fine. But after that it will resort to a limited access state after a few minutes as well as with the other instances that I was able to connect. The same thing happens if I try to restart it right away after connecting. It goes to limited access. If I disconnect and try to reconnect, it won't allow me to. It prompts me to a troubleshooting step which did not work at all. I've been trying all day and night to look up solutions but with no clear one ....
This one runs on Windows 7 btw.... The wireless adapter is just a 2x2 11b/g/n wireless lan m.2 adapter... updated drivers and everything. Also, none of our other devices such as mobile phones and an HP desktop have problems connecting.
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 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?
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.
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 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?
View 7 Replies View RelatedMy 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.
I recently discovered that my T520 has a SIM card slot (inside the battery slot)
I tried to put my cell phone SIM card in it, but there's no reaction (no "New device connected" popup dialog).
What should I do ?
Is there a driver + software that needs to be installed ? Which one?
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.

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 .
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?
View 3 Replies View Relatedi 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?
View 2 Replies View RelatedI 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?

View 5 Replies View RelatedI'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 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%.
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?
Is there a small/free application for download (preferably one that doesn't require going through installation process) that shows how each Windows applications accesses the internet, transfer rates and amounts of data being transferred?

This is bizarre...and makes the machine nearly useless.
I have been running ubuntu on my T420s for about 2 years now. Needed a Windows box to work from home so I installed Windows 7 Home Premium - Service Pack 1 on it. Installation went smooth but Windows did not recognize my wireless card, preventing me from connecting to the internet to download and install the rest of my drivers. I tried to manually install the Intel Wireless Lan (bg, abg, abgn) for Windows (64-bit) Centrino Advanced-N 6205 which is what I thought was installed on my machine to no avail.

View 2 Replies View RelatedI recently upgraded my Lenovo ThinkPad T400 with a Crucial M500 (240GB SATA SSD 7mm) and 8GB Kit (DDR3 PC3-8500 NON-ECC) RAM.
After a couple of days of trail and error I eventually installed (successfully, I might add) Windows 7 via USB. I leave my laptop on when I sleep, but in the morning it's shut off. When I power it on I get to the Windows did not shut down properly and I always select the "Start Windows Normally" option and additionally Google Chrome informs me that it wasn't shut down properly and restores my tabs.
Why it randomly shuts itself off... Also, when I try to run my system rating after one or two flashes of the screen my laptop turns off, so I am unable to do this as well.
I recently purchased a Thinkpad T440.
As a finance person I need to use the F1, F2, ....., F12 keys on a regular basis. My issue is that I need to always use FN+F1, FN+F2, ....., FN+F12 to work, which is not the most convenient thing to do.
Is there any way to switch these two? Going in the BIOS offers me only the opportunity to switch between Ctrl and Fn.
I'm tried hard-booting the device, but no dice. When I push the power button, I show activity in the status lights and can feel heat coming out of the heatsink. I think I see the 'ThinkPad' screen displaying very faintly at that time, but it seems not to proceed through the regular boot process. I'm definitely not able to get to a BIOS post.
