Lenovo ThinkPad W Series :: W520 - Bluetooth Device Not Recognized By Windows 7
Jul 18, 2011
Just received my Thinkpad W520 4270 CTO with bluetooth installed. It was a DOS workstation that I installed Win 7 x64 Ultimate on and I finally got all the drivers installed but the bluetooth software says there is no BT device connected to my laptop. I checked the BIOS settings and confirmed the BT is enabled. I even disabled it, saved, then enabled it to toggle. Hitting the Fn+5 combo doesn't trigger the light or any "Found New Hardware." When the laptop first boots up the BT light flashes along with the wifi light and the HDD activity light. I haven't yet been able to load another OS, but I'm downloading Arch Linux and BackTrack 5 to test to see it's possibly an OS issue.
I realize the sticky about the "do not update the bluetooth drivers" but I'm not getting my bluetooth to work at all, not even being recognized by the OS as an "unknown device."
The IEEE 1394 device is now completely missing from device manager. It seems like hardware failure. BIOS reset and factory restore did not resolve the matter.
I have contacted a local service depot so the machine will go in for warranty service next week (after labour day weekend) if not resolved beforehand.
This morning upon booting up my ThinkPad W520, the multi-card reader is no longer working. A look at the Device Manager (Windows 7, 64-bit) shows the "Base System Device", and reports "The drivers for this device are not installed." Attempting to get Windows to natively install the drivers does not work. Some googling shows others with similar troubles in the past; recommendations include installing a Ricoh card reader driver for Windows XP or Vista; this did not work. Other available drivers include 8ass82ww.exe and 8axv51ww.exe - these do not work. Installing Lenovo's own Support Center software shows the Base System Device driver is not installed. I can't find a way to install it. I've tried installing driver exe files and searching for those same files using the Windows browse-for-files window when installing drivers for Base System Device.
I've had this continual problem with my W520, which I can't seem to solve. Windows Search is disabled, I go into services, set it back to Automatic and start the service. It works fine all day long, no problems. When I shut off the machine, sometimes, not everytime, when I bring the machine back up, the service is now disabled and I go through this entire process again. What is strange is that at other times, after reboot, it is still enabled.
I've checked the event log, there is only an entry that indicates that the service was disabled, but there is no information in there which indicates the process that did the disable.
Here are the specs of the machine which might be relevant:
Hardware W520 x64 Win7 Ultimate - standard Windows build 2820QM processor 16 GB RAM 1x500 GB drive in the HDD bay 1x750 GB drive in the Ultrabay (with the annoying gap)
Software MS Office 2010 Visual Studio 2008/2010 SQL Server 2005/2008 ESET NOD32 Quickbooks Chrome othr related items for development.....
On the software side, I tend to keep it light, thus making it quicker and less likely to have conflicts.
Is there any tool out there which can tell me what process keeps disabling this service? It is very frustrating, having to go through this all the time. I know there will be some that say it slows down your machine, that may be their experience, but it is not mine and that penalty is outweighed by the convenience of being able to quickly search a 6GB email account.
Just upgraded from Windows 8.1 preview to Windows 8.1... since then my display doesn't look right at all. Resolution seems to be set to 1920x1080... which I belive is correct.
But text, icons and windows seem bigger than they were before.
Also the display is lacking sharpness around text. Do I need to upgrade some drivers or something?
I have a new W510 but I cannot get the fingerprint reader working for Windows logon. I have the Lenovo fingerprint software installed. It can enroll my fingerprint with ease, which also shows that the reader works. I have turned on the option "use fingerprint scan instead of password when logging into windows". When I restart Windows, I see a fingerprint logon option, but it still defaults to CTRL+ALT+DELETE. When I pick the fingerprint option and scan my fingerprint, the lght blinks twice and nothing happens. I know from my old W510 that I should be seeing a Lenovo Fingerprint icon on the logon screen, but I just cannot get that to display. What have I missed?
The virtual agent was no support - it gives me a setting that doesn't exist, tells me to reboot, tells me that the first time I log in I will need both fingerprint and password, but afterwards it only needs fingerprint.
I upgraded my w520 from Win 7 to Win 8 last year with zero problems. Now I upgraded my W520 Win 8 to Win 8.1 via the store download. Except the webcam everything works fine.
In e.g. the Skype desktop application, Google Hangouts or the camera app, the built in webcam no longer works.
The green light turns on, but I just get the crossed out camra icon in e.g. the Skype video options. No video.
I see there are no drivers yet for Win 8.1 on the Lenovo support site for the w520 camera. In device manager it still shows the 2011 camera driver 1.1.0.1147 and says "This device is working properly."
But it does not work properly. How to get the camera to work or is it just a matter of waiting for a driver to be released eventually?
I tried uninstalling, reinstalling, camera is enabled in the Bios and permissions are set to give Skype and the camera app access to the camera. I also tried the W530 drives as was suggested elsewhere.
I rencently reinstalled windows 7 on my W520 and it refuses to activate my nvidia quadro 2000m (Code 43).
For a while the fan is overheating and the right left hinge become very hot. I think the graphic card is dead but I want to know why and if I can stop the overheating. Is the the graphic card soldered onto the motherboard of the W520?
First my notebook specs Lenovo G570 (part number: 43345JU) i5-2410M 8GB RAM Qualcomm Atheros AR9285 WLAN dont know the make of bluetooth (mostly broadcomm) Came with Win7 Home premium x64
The Win7 that it came with also had lenovo energy management through which I could toggle the WLAN and bluetooth on and off. Since I never used the bluetooth, I turned it off via energy mgmt.
Also interestingly, when I was running Win7 I had it dual boot with Ubuntu. And if my Bluetooth was turned off via EM from win7... bluetooth wouldn't be recognised in ubuntu and there was no way of turning it back on... I had to boot back into win7 and turn it on via EM and boot back into ubuntu.
Recently I updated to Win8.1 but hadn't turned on the bluetooth before doing so. In Win8.1 the bluetooth device is not recognised anywhere..not in PC settings(metro UI), not even in device manager. I tried to install the energy management for 8.1 from the support site but it was extremely buggy and didnt find any option to turn on bluetooth. The old EM didnt install properly in comaptibilty mode.
In ubuntu now (dual boot with win8.1) its still the same. Bluetooth not regonised just as before.
I cannot go back to win7 now. There is no proper EM for win8.1. There is no option in BIOS regarding bluetooth. How do i turn on the bluetooth adapter?
I was able to install a new: PNY Optima SSD7SC240GOPT-RB 2.5" 240GB SATA III Internal Solid State Drive (SSD) in my ThinkPad X220 model 4287. I installed the latest BIOS before the upgrade and did a clean install of Windows 8.1 Pro. The installed went smooth with no issues. I proceeded in installing all Drivers and utilities. Then I noticed that when I restart Windows, the BIOS does not recognize the drive and proceeds to try to boot from the Network, Intel Boot Agent. It does not seem to recognize the SSD drive.
The only way I can get it to boot from windows again is to TURN OFF using the power button and then turning it back ON. I tried the Lenovo SSD firmware update utility to see if my drive needed an update but it did not find any update for my drive. I also tried to the PNY support site and downloaded the firmware update to see if it found any updates for my drive and none where available. I hope LENOVO can release an update to their SSD firmware update tool to fix my problem. I am also not sure if any of the utilities that I installed may be the root of the problem. So right now the only way I can get Windows to load is to turn off and turn back on the laptop. Windows restarts will not work.
i recently bought my W520 and everything works just fine - except for the internal webcam.
I installed the drivers (current version) from the Lenovo web site but the webcam won't turn on. The green just wouldn't turn on and when I press Fn+F6 the communication tool shows up without any webcam video. Same thing for skype or any other webcam tool.
Sometimes after booting it works for a few seconds but then the image freezes and it won't start again until after several system restarts.
System Details:
Thinkpad W520 (4276), Core i7-2760QM Windows 7 64 Bit Professional
When will there be a BIOS update to fix the UEFI/Bitlocker issue? The TPM won't pass the keys to Windows when UEFI mode is on. An X220 owner has this issue as well: [URL] ....
I realize that there are several threads on W520 shutdowns, but I haven't quite found a similar problem to mine: A random, sudden shutdown occurs while the laptop is on battery. The problem does not occur when using the power adaptor. It also seems to have nothing to do with physical movement of the laptop, nor with power consumption/heat. After going blank from one second to the next, the laptop restarts. Seeing that the laptop works fine with the power adaptor, is there any reason to believe that components on the main board could be the problem? If not, I could just get another battery, even though this still seems ok.
I have 2 x 4GB sticks of G.SKill F3-8500CL7D-8GBSQ DDR3-1066 PC3-8500 CL7-7-7-20 SO-DIMM.
They worked perfectly as the only memory sticks in a W500, but I'd like to install them in addition to the 2 x 4GB Lenovo memory sticks that came with the W520.
Is this going to work and be stable at all? After reading the W520 specs, I'm still uncertain about the memory speeds of the two different sets of sticks and if that is a real compatibility issue. I don't know enough about memory specs.
I just updated my ThinkPad W520 using the System Update utility and after rebooting I realize that the battery icon is totally gray and shows the message "Battery not installed". Checking the installations log of System Update I see
-Lenovo Power Management Driver 1.67.04.05 -Power Manager for Windows 7 6.66.1
And the Windows battery icon shows the info correctly. Is there any way to uninstall the updates?
Currently using Norton Identity Safe's standalone password manager, but would like to start using Lenovo's instead. Attempted to import .DAT and/or .CSV files from Norton, but no option for these file types appeared in Lenovo's Password Manager.
If not an option to import directly, is it possible to add one of the files to the location Lenovo stores the password manger entries?
Btw my mobo,cpu,memory i believe were all replaced last time i took it in with this issue... Still getting it consistently:
Random Black Screens and Random Sleeping: [URL] ...
Black Screen: [URL] ...
I thought before maybe its Bluetooth related as sometimes when screen would turn black and then come back, I would get a 'Bluetooth Device Not Discoverable'. So turned off Bluetooth in the BIOS, but still having display/sleep issues.
I removed hte Lenovo Power Manager/PM Driver, and turned off sleeping in the Windows power settings (in every setting including if Low Battery Action).
Using Win 8.1 x64 and the latest Synaptics drivers, if I'm typing or holding a key the left click does not work. I've tried every setting in the Synaptics control panel and can't figure out how to disable this behavior.
How to disable this? It's very annoying, especially as there is a delay after pressing a key before I can click the mouse of around a half second.
Easily recreated by opening notepad and holding down the A key, then trying to left click something.
I have a w520 that is out of warranty. From time to time, the screen just turns off while I'm using it (no, not a dimming/screen off during idle isse). Everything else works perfectly though. I have to shake the laptop (lol, seriously...) and the screen comes back on! It's been getting more and more frequent. What gives? Is this a known issue? Is there some loose connection somewhere inside? What should I check?
If the system has been on battery at any point of the session, color calibration seems to mess itself up according to what's on screen. If darker colors dominate the screen, the colors slowly (but visibly) go all weird. When there's mostly white content on screen, it returns to normal.
I've been browsing some power management settings and none of them seems to relate to this. The system is W520 with FHD screen, Intel 8.15.10.2538 drivers, Nvidia 332.21 drivers, Windows 7. This does not occur in Ubuntu, nor on an external monitor.
I was able to install and configure all drivers but one. I found a tread that suggested installing Lenovo Setting Dependency Package 2.0.0.13 to fix it on a different lenovo model. I tried it without any success.
The driver id of unknown driver is "{48126E0D-4BDD-4D26-8A24-569C7AB522D6}SettingsDriver"
I am using Lenovo W520 with windoiws 7, RAM 8 GB. It is very slow and when I type something it appears with noteable delay. Also i am using virtal machne windows XP there. How can I get better performance
it appears my windows 7 32bit thinkpad x200 has question marks at bluetooth adapters in device manager.
I have installed the drivers that are available on the website of lenovo producer, but no change is observable.
The device seems to work well, that is share and access files with android smartphone, and use android's internet, but when it comes to sharing internet with the smartphone, there is no transmission. I wonder if broken drivers could be the cause.
I'm trying to have simultaneous sound from both the headphone jack as well as the internal speakers. I've enabled the concurrent audio via the Smart Audio panel (Audio Director), tried the blue and red buttons (got successful results), but all of the computer sounds still come from the headphone jack.
I have a quad core Lenovo W520 (i7-2820QM) equipped with Intel AMT. I have all RAM slots populated (original 2GB in each that came with the machine). I have updated to the latest BIOS (1.42 at the time of writing) and latest Intel Management Engine Firmware 7.1 (7.1.85.1216 at the time of writing). The machine has Crucial 256GB X100 SSD installed in the main compartment and a regular HDD in UltraBay.
The computer acts normally in sleep mode and restart sequence only when Intel AMT states that "ME is in recovery state..." during boot.
When it looks like AMT is happy problems begin. The problem is that when I'm trying to put the computer to sleep it goes all the way until the end per normal procedure and then suddenly decides to power itself off! Obviously Windows doesn't like this and displays recovery suggestions after starting the laptop again. This happens when connected to AC and also when disconnected from it. Also, when computer reboots it turns off all power (i.e. the display along with backlight, indicator LEDs turn off and fans spin down for a sec) inbetween and automatically starts up after that.
I've tested this on Windows 7 and openSUSE 13.1 (which I had lying nearby) and same behavior happens on both OSes. On Windows, all the latest drivers and updates were installed. So I don't think this is driver nor OS dependent - rather firmware/hardware related problem.
What is funny, it doesn't matter whether Intel AMT is activated in BIOS or not. What matters is whether the Management Engine is in some kind of recovery state or not. When it's not, computer starts acting crazy as stated above and behaviour is repeatable. Intel AMT itself seems to work however. Changing the power policy in Intel ME configuration doesn't work for sleep issue.
Some things I've also tried doing: * Replace CMOS battery (measured its voltage before putting it in, of course) with a new one - no effect * Tried two different brands of SSDs (OCZ Vertex 3 and Crucial X100) - no effect * Tried both legacy and UEFI modes - no effect * Scanned RAM for memory errors - no effect
Could Lenovo try to repeat this issue and possibly do something about this?
I researched I need the Intel SATA AHCI Driver for performing a clean Windows 7 installation
I tried:
1. Mobile Express Chipset SAAT AHCI controler drivers from the (a) Intel websites (b) Lenovo website and (c) extracting drivers from running system 2. tried supplying drivers on DVD/CD and USB 3. tried to integrate drivers into Windows 7 Installation using RT7Lite 4. did bios update 5. switched from AHCO to compatible mode
In any case it finds the driver as the correct one (when I click hide drivers that are not compatible, the one remains). But always displays no driver found and doesn't continue setup.
This seems to be a bug!!! 1. Is there a way to fix this and perform a clean Windows 7 installation without recovery? 2. Am I trying the wrong driver, but have to install a driver for a different device first???
I am about to replace the HDD with an SDD and there can not use recovery!
