Lenovo T400 / T500 :: T420 - Base System Device Driver Not Working On Windows 7
Jul 7, 2014
After reinstalling W7 the lenovo solution center was complaining saying that the System Device Driver is not working. I saw that the SD card reader was not working neither so I assumend the missing driver was that one.
From the Lenovo page I dowloaded the driver for the Multi Card port for W7 and T420. After installing it the message dissapeared and the SD cards were recognized properly.
However, after rebooting the system, after a while, the mesage appeared again and the card reader stopped working.
I did install it again and the same happened. It was working and after two reboots stopped working.
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 received a T410 and worked two days on it. From one office I moved to another location and worked for some hours. After lunch I started the machine again, but neither touchpad nor keyboard is working. If I connect a pointer via USB on the machine the pointer is working, keyboard unfortunately not.
Ok. Admins installed it new. I worked one day, next morning same issue. Well, back to admins, reinstallation completed. Again for two days I could work without any problem. So as it happened the third time admins decided to provide me a new hardware: I received a T420. I have been working with this one week without any error.
I took the notebook home. I had been working with it for one hour. I used a USB-to-bluetooth wireless pointer. No problems so far.
I got back in the office this morning an guess what?!?!?! Same problem as for the T410: Windows is starting up but touchpad and kayboard is not working at all!
What did I? In my opinion nothing special: 1) Started up machine 2) Added pointer 3) Connected via WLAN to network at home (settings for Home-Network applying) 4) Packed the notebook into my suitcase and took the flight. 5) Back at the office connected via LAN to network, connected via VGA to monitor, added usb-keyboard, added pointer.
What can this be? I mean I'm able to destroy to different machines! Only common is Windows 7 and T4xx series...
Ever since i've wiped the machine, i've been having these two problems. When I close the lid, it used to go to sleep straight away, but now I can see the sleep light (and the power button) flash and flash, then it goes to sleep. When waking up it goes through the lenovo startup screen and resuming windows, then it asks for a password, before I used to open the lid and it would ask me for the password straight away. I know it was going to sleep because I could hear the beep straight away when I closed and opened it, but now it just takes too long.
Also, everytime I boot up into windows or resume into windows from a sleep state, I can hear the device noise, like something is being plugged in/out. But there is nothing being plugged in or out at the time. I can't get to device manager quick enough to see what it is that is causing it. But all drivers seem okay.
Also noticed, when the lid is closed, randomly the laptop turns off (hear the beep) an then turns back off again.
T420 model number: 4180-PR1 with OS: Windows 7 Pro 64 bit
I have Accer aspire e1-571 i want to know abaut base system device, i have installed all drivers in my laptop but base system device driver pending i want to knw how to install it. os win 7 pro 64 bit
I bought t420 last month. Yesterday i spilled liquid on the clicks on touchpad. The right button works but it freezes sometimes, left doesn't work at all. Because i am in Europe now,the warnity does not cover. Also the ultranav buttons don't work. With external mouse it works.
I bought my Elitebook 8560p a few weeks back off of a friend. Wiped the entire laptop clean and installed a new OS (Windows 7 Ultimate 32 Bit). I thought I installed all the drivers, but the device manager says im still missing a "Base System Device" driver.
I have a wireless mouse and printer plugged into the USB ports of my docking station and generally have no issues with them functioning. However, when I take my laptop off the docking station and then return it to the docking station, the laptop no longer recognizes the keyboard and also says that the printer is not connected. Once I restart they both work. I have also tried to unplug the wireless receiver for my keyboard from the docking station and plug into the laptop, but it still does not work without reboot.
I have a T420 that I'm using with a Mini Dock Series 3 - 90W 433710U docking station. I'm trying to connect to two external monitors (both HP 1965's) using the DVI and VGA outputs on the docking station. From the VGA output, I'm running a VGA (M) to DVI (M) into my monitor. I can only get either the DVI or VGA outputted monitors to work by themselves, but not together. When I connect both external displays, it will switch off one of the external monitors (the first one connected). Both are verified working as external monitors with the T420, just not at the same time. When using the DVI output, I can get dual monitors to work using the ThinkPad display as one monitor and the DVI-connected external monitor as the second. Is there a way to connect to two external monitors from a T420 with a Mini Dock Series 3 - 90W 433710U docking station? Or do you a multi-monitor adapater, such as an Cirago HDX3DV01 to do that?
Is it safe to swap hardrives that are running windows 7 between two t420's? I have read in the past that the OS is tied to the hardware and doing such a swap will cause errors or blue screen.
Today I upgraded from Windows Vista Home Premium 64-bit to Windows 7 Home Premium 64-bit and all of my drivers were found without me needing to install anything except for one. In the device manager I have an exclamation by 'Base System Device
Recently I did a clean windows 732 bit installation on my Hp dv2500 notebook because i was having some problem with the original vista OS. Anyway I noticed that, under device manager 3 drivers were missing...namely:
I've just recently upgraded my system from XP to Win 7 and I've been unable to find drivers for two "base system devices". I'm on a Compaq Presario V3440TU and my CPU is a Core 2 Duo T5300, and chipset is Intel 945GM.
The missing drivers are most probably for the Ricoh Card reader in my laptop, since I remember facing the same problem while re-installing XP once...
on my HP Pavilion dv 9500 series laptop installing Windows 7 Ultimate, I get base system device error, base system device driver not found. devices are on - PCI bus 7, device 9, function 2. & pci bus 7, device 9, function 3. these are found in the device manager under other devices.
I have a HP Elitebook 8440p Notebook PC with Windows 7, 64 bit. I had to reinstall Windows 7 and all the necessary drivers. My remaining issue is the Missing Base System Driver. The message I get from Device Manager is:
PC1 bus 68, device 6, function 2. The driver for this device are not installed (Code 28).
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?
I recently installed Windows 7 on my vostro 1015. All the drivers were installed correctly but the 'Base System Device' driver couldn't be installed. I tried the 'Search Automatically for the updated driver software' option but no driver could be found. where can I find the 'Base System Device' driver?
I have a machine (used for creating master images) with all the drivers loaded. I perform a last CloneZilla image (before doing the sysprep). When I restore the image (to the same machine) the Ricoh Card reader has status of Base System Device under Other Devices. I have tried reapply the drivers, deleting the device with drivers and rebooting so that the machine can redetect the device. No luck, just stays at Base System Device.
I purchased this wonderful machine from a friend of mine after he had me install a copy of Windows 7 (64) onto it. I am not entirely sure when this problem started.
Problem: I can access my BIOS, but my settings are completely greyed out, I cannot select, much less change anything in it. After startup and I press the "BLUE" button, it prompts me for a power up password, so I press the enter key without typing anything in, which is how I believe I set it, and it allows me to "see" the BIOS settings. I am never prompted for a SVP as I do not believe there is one, although when gazing into the mystic BIOS I see the security settings are as follows-
SUPERVISOR PASSWORD [ENTER] PASSWORD STATUS ENABLED LOCK VEFI BIOS SETTINGS ENABLED SET MINIMUM LENGTH DISABLED PASSWORD AT UNATTENDED BOOT [ENABLED] PASSWORD AT START DISABLED
The entire section is greyed out, and I do realize that I am indeed missing some settings that ARE in my BIOS, such as HDD Password (NONE) and I believe something else.
I am trying to edit my display and optimus settings, as I am an avid game player, and the NVIDIA card appears to be a much better option, but I however, cannot.
I seem to have a failed brand new SSD. Before I RMA it.
-I've just used Samsung data migration to copy my C drive to a Samsung 840 Pro 128GB SSD as usual. -I went into device driver, and set the SSD to cache writes, so the SSD was working then. -I removed the 320GB SSD, installed the SSD and rebooted. -After the BIOS flash screen, the system halts with a funny symbol on the screen and a flashing cursor. -It responds to Ctrl Alt Del. but doesn't get as far as testing the DVD drive. -After replacing the SSD with the HDD and rebooting, all is fine again ... -The BIOS shows AHCI mode, and the SSD and contents (in a USB3 drive caddy) are visible and readable.
I can't use Samsung SSD magician because it won't see the SSD over USB (clever!), so can't work out how to upgrade firmware. This is an i5, 8GB, 320GB machine with 1600x900 screen, with XP Pro 64-bit.
What gives?? Others here have posted with working 840 Pros in a T420, so I think it's compatible. Could this be a SATA2/SATA3 thing or AHCI? I can't see any SATA2/3 control in the BIOS - does it just auto-negotiate?
