I'm facing an annoying problem with my T420. When in battery mode the machine goes to sleep after some minutes. WHILE I'm working on it... But than it is NOT possible to wake it again.
View 8 RepliesMy 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.
View 7 Replies View RelatedI have a T420 with Windows 7 SP1. I bought a replacement battery of 0A36303 (ThinkPad Battery 70++ (9 cell)) and got one with a new Replacement part number (FRU) of 45N1007 (it is clearly written on the battery alongside “ASM P/N 45N1006”).
[URL] .....
After I installed it in the laptop and made sure to run System Update and update all the Lenovo software to its latest versions.
I also run the Lenovo Battery Firmware update utility, which informed me that the battery has the latest firmware (0003-0080-0100-0165). [URL] .....
When I run “Power Manager” (latest version, 6.66.3) and choose the tab of “Battery” I have this mismatch data:
Both “Design Capacity” and “Full Charge Capacity” shows "90.00 Wh" which almost fits the characteristics of the 0A36303 battery (as detailed at [URL] .....) which is "94 Wh" (in compare with "57 Wh" for the 0A36302 model, detailed on the same web page mentioned above)
But the “FRU part number” field says “45N1001” which fits the “0A36302” model… (as detailed at [URL] ....)
Why is this mismatch?
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 run Windows 8.1 on my T440.
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.

I have a 320 GB HDD, but it's nearly full, I am thinking about buying an SSD.
I wanted to know is it possible to have 1 SSD and keep the existing 320GB HDD and run it alongside each other?
If so, where would the SSD go?

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?
I am getting a T420 as my new Corporate laptop. I want to buy an SSD drive to replace the internal hard drive. I found the newest bios/firmware and looked at the Readme file. It lists the latest drives and model numbers but not any of the previous models? How do I get a complete list of all SSD drives/models supported on the T420? The laptop is going to be imaged with Win7 if that matters.

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?
How could this battery drain be avoided?
My T420 has the 2100 error on HDD0 few days ago. I went to the IT center and found the hard drive is completely dead. My original hdd is 500G seagate. So sad, all the music and good memories are gone.

My T420 doesn't power on at all. I have tried to turn it on with cable, w/o cable, different baterries, removed rams and tried same things, tried holding down power button for 60 secs, tried with an other keyboard and I couldn't manage to start the laptop. No reaction at all, no blinking or anything.

I consider buying a new notebook and T420 is a hot candidate for me. I'm not sure yet whether I would go for a Core i5 or i7 processor, however I'm sure I'd like to upgrade the RAM in the future and 16 GB . I found out in the Intel specifications that (not only) the i5 2540 and i7 2640 that are available in the T420 configurations support up to 16 GB RAM, however in the T420 specifications concerning those processors I found that only 8 GB of RAM are supported. AFAIK the memory controller is integrated in the processor in these cases, so is there another factor that limits the size to 8 GB, or is it only an improper information in the T420 specs?

View 2 Replies View RelatedI 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 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.
View 7 Replies View RelatedI purchased my T420 one year ago and have sufficiently "hosed it up" to the point I wanted to do a factory restore. I saved all my data then proceeded to create the CDs from the Q drive factory restore. I followed the instructs for more and more CDs and once I got up to #12 I noted that the time it was taking to create them was down from several minutes to several seconds. When I got to CD number 18 I thought "this is ridicules" and I popped CD 11 back in to look at its content (via Windows Explorer). I noted it had two folders: 1) Factory restore (or something like that) which was over 500 MB in size and 2) something about data. This "data" folder contained 1 KB of data. I then looked at all subsequent CDs (12-18) and they all only contained this data file. So, rather than continuing to make these (basically empty CDs) I stopped.
I then put the first CD in and rebooted the machine. The factory restore started and I swapped CDs until I got to 12. I put 12 in and it said the required data was not present and to insert the next CD. I did this until I ran out of the CDs I had created. I had to "X" out of the restore app and now when I boot I get nothing but a dimly lit screen and a flickering hard drive light! Am I totally hosed here? How many CDs would it have required had I kept making them? I am ( obviously) a novice.
I noticed a strange thing to my T420 - when SpeedStep is enabled CPU switches to lowest speed periodically which immediately affects performance. It switches to lowest speed even when CPU is at 100%. Then after few minutes it comes back to normal.
View 6 Replies View RelatedI 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...
