Lenovo T400 / T500 :: How To Update Adapter To AC Mode
Feb 12, 2010
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'm not sure if any other user has experience this issue. I did a lenovo update couple weeks back and since then my wireless adapter would not work after waking up from sleep mode. It shows that the wireless adapter is connected to wireless network but the internet would not work. The only way i can make it work is by disabling the wifi adapter by putting the laptop in airplane mode and then bringing it back out from it. Disabling and enabling the wireless adapter does a quick fix and does allow me to use the internet without any issue for the time being. i have also uninstalled and reinstalled fresh drivers from lenovo website, still having the same problem.
My T500 (2241-3XU with Win 7 64 bit Ultimate) has never been able to wake up from sleep mode after lid is closed. I finally reverted to using hibernate but was just wondering if there is a new fix that I am not aware of. I tried to find info a couple of years back before switching to hibernate.
I just bougth the T440 and I have two main problems related to sleep mode, which both seems to happend randomly.The most common problem is that when I close the lid (the action suppose to activate sleep mode), the computer seems to freeze during the time it is going to sleep : The red light is still on as when the computer is in 'normal mode', but there is no display and the keyboard seems unresponsive. I have no choice but to restart the computer.
Sometimes the computer seems to enter in sleep mode correctly (the red light slowly goes on and off, which according to the manual indicates that the computer is in sleep mode), but when I open the lid, the screen remains black and I can see nothing but the mouse. I have no choice but to restart the computer.
It also happened once that the above problem (the second one) kept occuring even after multiple restart of the computer. The only way I could solve it was by using 'windows safe mode'. As the problems occur randomly, I am unable to say if they were already there when I received the computer, or if they started to happen after the few windows updates/software installation I did.
I have a T430 that is a couple of months old. I've had this problem from the very beginning. Decents specs (have a Dell laptop with same specs and it never has this issue).
Processor: Intel Core i5-3320M CPU @ 2.60 GHz RAM: 4GB
Basically, after every time the laptop is in sleep mode for more than 30 minutes, once I open up the laptop and log in, there is a period of 3-4 minutes where it is EXTREMELY slow. The computer lags ridiculously...
I have a T440, and I've set in BIOS to swap places for fn and ctrl. This works great until the machine goes to sleep or similar. After awakening the machine the keys are back to their original setting, with fn being fn, and ctrl being ctrl.
I havent explored this in detail but just found the machine sporadically losing the setting, but never while I'm working on it. So either from sleep or from locked screen.
I always use FnLk as well and that is also lost when this happens. I have to restart to get back the setting for fn-ctrl swap, but FnLk i can just enable,
I have the T540p with Win 8.1, actual drivers. Updates as in the web site. It works in the Ultra Dock with a 135 W power supply.
Attached to the Dock are following USB Peripherals
1) MS Keyboard 4000 2) Ms Mouse 3) Web Cam (Logitech 920)
After some time (sometimes 10 Min after booting, sometimes longer), the USB ports do not work. Unplugging the peripherals and plugging them into other USB ports of the dock does the trick, but the previous ones do not longer work until the next start.
The Screen goes blank. Sometimes but not always I get a message from the power manager stating that plane mode has been initiated due to power supply problems. I have tried connecting the thinkpads own 135 w supply, but no difference.
When you open the machine to boot, I must open in the corner from 0-40 degrees. I have to slid hand to press the Power button, the computer boots normally into Windows 7. Then:
- When I open angle greater than 40 degrees (40-180 degrees), the machine switches to sleeping. - When closed off the screen in less than 40 degree angle, the machine is turned on (switch to normal working 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..
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 been having off and on BSOD issue and I was advided to possibly update my video driver via this site to the latest. The problem is that when I try to update it keep telling me that my laptop does not meet the minimum requirement and it would abort the update.However, I dont get why it wouldn't meet minimum requirement and it doesn't note anywhere within readme file what is the minimum requirement to install this latest video driver.
I think my attempt to update BIOS with a "BIOS update bootable CD" method has failed!
My laptop: Lenovo Thinkpad T420, i5 @ 2.5GHz, 4 GB RAM. My old BIOS infos (taken from Setup before update attempt): UEFI BIOS Version 83ET52WW (1.22) UEFI BIOS Date (Year-Month-Day) 2011-03-24 Embedded Controller Version 83HT27WW (1.11)
I intended to update my BIOS to version 1.46 using "BIOS Update Bootable CD" from this link: [URL] .....
Steps: 1) I downloaded this ISO image: [URL] .... and burned it on a DVD-RW(DVD rewritable) medium. 2) I placed the DVD in my T420 and turned it off, then turned it on, select F12 (boot menu), selected DVD to boot from, and the BIOS update utility started. 3) In BIOS update utility I pressed "1" to read the instructions, then press "2" to update BIOS. I clicked "Y" to confirm and the update operation started. First it said " Now updating... ", then afer about 2 minutes, it said "Still updating ..." and it stuck like this.
So, right now, this message stays on my screen for about 1,5 hours(!!!):
"Still updating... It may take about a few minutes. <<< CAUTION >>> Do not turn off the computer during the update. Do not remove the CD during the update."
Other details (on system setup and current behaviour): AC was continously plugged in before&during BIOS update, battery is OK, no hard disk activity at all, keyboard is(seems) unresponsive, system's temperature is pretty high, but not dangerously high...
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%.
My Thinkpad T430, less than a year old, is having issues - corrupted .dll files, Windows Update not working, all sorts of fun stuff. I've exhausted pretty much every other option I can find to try to repair this at this point. The nuclear option is a reset to Lenovo factory settings from the Windows repair environment accessed by pressing F8 during boot, but before I do that I want to understand *exactly* what I would be doing to my computer.
Specifically: will a factory reset return all Windows system files to their original state, meaning there is no chance that the issues I'm having will persist? Will it guarantee that Windows Update will work again and that all of my .dll and other system files will be in a fresh, non-corrupted state? Does the process replace current system files with original versions that were installed on the computer?
I just don't want to restore to factory settings and find that Windows Update still won't work and now I have to install over a year's worth of updates manually from the Microsoft website, one by one, or go through the trouble of having to reinstall all of my programs, get my files back on the computer, fix settings to be as I want them again, etc. only to not have these issues fixed.
I updated the BIOS of my TP T410 (2522), German keyboard, to 1.45. After the update both CTRL keys do not work any more. The same for AltGr. When I activate the FN CTRL switch in BIOS the FN key - as supposed - works like the CTRL key. But when I deactivate it again the FN gets back to its proper function and CTRL does not work.
When I connect an external keyboard via USB it works perfectly. How to get the CRTL key working again?
On my T540p, I configured the rapid start technology according to [URL] ....
Since I have performed a BIOS update to 2.14 and an update of the Intel Wifi driver to 17.0.5, I experience the problem of battery drain when the computer is in S4 sleep state, at a rate of approximately 0.125% per hour (on the 56Wh battery).
This was not the case before these updates. There was no noticable power drain in S4 sleep state, even not over multiple days. I'm using Win7, I set all the WoL capabilities both in BIOS and in the Intel driver to disabled, according to [URL] ....
External device USB charge settings are also fully disabled in BIOS and Power Manager. The problem does not occur when the system is fully shut down, but in S4 Sleep state, which should be a zero-power state too, as it was before the updates. In the details of the BIOS update it is stated " Fixed an issue where the computer might fail to enter sleep state". Could the power drain be a side effect of this fix? Or is it an issue with the (new) Wifi driver, as it was the case for the Y410P?
I can't get into the bios anymore. I updated the bios via the BIOS Update Utility 2.56 and after that I can't see the "press enter to interupt normal startup" message anymore. And therfore can't get into the bios. Windows is still booting normally.
I have just installed an i7 2670Qm on my T420 today.The machine will crash pretty soon after booting up, with the screen having colorful vertical and horizontal lines before it restarts itself and give the memory error beeping pattern (1 beep-pause-3 beeps-3 beeps-pause-1 beep).So then I took out one RAM from the bottom, and the machine appears to work normally again, more or less.
In the OS (Win7 64), The power manager alerts me that the 65w AC adapter is giving not enough power, so the laptop is running on battery. I thought I just need a 90W AC brick so the laptop will work as it should, so I am arranging a 90w one to come in later. But on a second thought, if the battery cannot start the laptop with 8GB of RAM properly.
Is it the CPU or RAM or Mobo or something else? Where should I look?The machine works fine with the previous CPU i3-2310m and 8GB of RAM.The RAM modules I have are 2 x 4GB Samsung 2Rx8 PC3-12800S-11-11-F3.The BIOS version is updated to the latest 1.46.
Bought a refurb T400 and installed a PNY SSD in it. It POST's okay and I can access bios. I can also read/install Linux from DVD just fine.
Trouble is when I insert my win7 home premium DVD into the drive and boot it, I get POST and then I get a black screen. It seems to be reading the drive and when I interrupt with the Esc key or open the DVD drive, I get a Windows menu explaining that the installation has been interrupted.
I've looked at the bios options and can't see anything obvious that should be changed.
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?
Is it possible to run a t500 without a battery? I found a t500 in my basement without a battery or adapter, however i am not sure if it works or not, so i was wondering if i could just buy the adapter to see if it boots up or not because i don't want to go through the process of returning etc.
I recently got a T440s and wanted to replace the hdd with the SSD from my old laptop, and it is not being detected at boot. It works fine in my e420s.The SSD is a Kingston V+200 240GB. It's a 7mm drive.When I turn on Diagnostic boot in the BIOS I get the following error message:
PXE-E61: Media Test Failure, check cable PXE-M0F: Exiting Intel Boot Agent.
It seems like their is a problem with the connector? The SSD in the computer can actually wiggle around a little bit (<1mm), it seems like it shouldn't do that.
A key ? for me in purchasing a new machine is how to arrange 2 accessories: DVD player and a 2nd drive (primary drive would be an SSD).
From what I understand, I cannot swap out a HDD and DVD in the ultrabay--if going with a second HDD, the HDD is permanently installed. This implies that you make the pre purchase decision to either have a HDD or DVD player connected by USB and the other in the ultrabay.
Would one opt to have the HDD in the ultrabay due to increased data throughput vs. a USB 3x port?
