Lenovo 11e E/Edge :: 0302-2BU Missing BIOS UUID And Serial Numbers On ThinkPad
Dec 13, 2011
I am currently working on a ThinkPad Edge 15 0302-2BU for a client of mine. The system is able to POST and I can enter the BIOS but the UUID is all zeros and the Machine Type Model, System-unit serial number, and System board serial number are all blank.
I went to the support page for this model and downloaded the ISO file with bootable BIOS update utility for BIOS ver. 2.20 (82ET80WW) I updated the BIOS in case there were any issues with the current BIOS release. Rebooted then went to update the model number off the bootable utility. I entered the model number, Updated, and Rebooted again. Still having the same issue. The model number didn’t record after I punched it in.
I am still able to POST and get into the BIOS configuration. The system will not load an OS or boot off a CD into something like Windows PE.
I'm not sure if Windows not being able to load is due to the BIOS or not but I'm inclined to think so since I have trouble booting off CD.

I got a really annoying problem with my E330. It came without an OS, so I put Win 8 on the preinstalled HDD. Then I switched it out for a SSD and put Win 7 on it. (everything in UEFI mode)
Since then I can't get into the BIOS/UEFI anymore by either pressing Enter or F1. Pressing Enter still gives me a beep, but then Windows continues to load normally instead of showing several options like it used to do.
And yes I'm aware that I need a cold-boot in Win 8 to get into UEFI ... The only way to access UEFI at the moment is through the Win 8 charms-bar restart into UEFI trick.
I tried already to reflash the BIOS which doesnt work obviously since it's the same version, tried removing the CMOS battery, that gave me a one time opportunity to get into the UEFI with F1 when it complained about the date/time.
Switching to Legacy only leads me to an infinite PXE - something error loop, but I still cant get into the BIOS.
I tried pressing every combination of Fn+F-Keys and without Fn. Nothing works. I don't want to return the notebook, but it's a deal breaker for me if I can't get Win 7 running on it with accessible UEFI.

I recently bought a t440s from a friend, And i wanted to lookup its warranty.The serial under the battery is recognised by the lenovo warranty check, But in the bios the serial shows up as R8000000, Could this become a problem for me in the future? refrain from bumping your thread(s) / post(s) more frequently than 3 days. Doing so, unfairly, pushes other members' threads downwards.

I'm trying to locate the serial number of my laptop and it appears to have been removed. It's not under the battery. Is there somewhere in the operating system that I can retrieve this information?

I recent did Microsoft and Lenovo updates and I have lost the On-Screen Volumn display. Not the Volumn icon in the task bar, I lost the display that shows the volumn going up or down on the screen. The video support suggested installing Power Management but this did not work. I have tried uninstalling and reinstalling the audio drivers, also did not work.

I have a newish (4/2014) Thinkpad E440 with a 500 GB HD. All of a sudden, the hard drive has filled up. I cannot account for all of the space. Here's what the system says:
35.2 GB available of 452 GBApps: 31.4 MBPictures: 76.1 GBVideos: 137 MBMusic: 20.9 GBDocuments: 8.14 GBDownloads: 0 bytesRecycle bin: 0 bytes
So you can see this is a wee bit over 135 GB. Where in the world is the rest of the space? Here's what I've looked at / done so far:
"System Protection" is turned on and is currently using 10.48 GB. I have the max set at 3% (13.59 GB). There are currently 3 saved restore points. --> EDIT now it says it's using 5.97 GB and there are only two restore points now.I've run "Disk Cleanup" and it says I could regain 33.6 MB. Whoo-whooooo!The disk was 1% fragmented so I ran defrag.I ran the error checking tool on the drive and it said there were no errors on the drive. Now, after finishing the defrag, I've lost more space "as we speak"20.4 GB available of 452 GBApps: 31.4 MBPictures: 76.1 GBVideos: 137 MBMusic: 20.9 GBDocuments: 8.14 GBDownloads: 0 bytesRecycle bin: 0 bytes
FYI: When I go to Lenovo Solution Center and click on Support and then go to Configuration History, the calender there shows the yellow triangle with the exclamation point in it for "System Events" on every single day that I use the laptop. When I click on one of those days, it shows multiple "Application Errors". This has been going on since the day I got it. I don't know if there is a log somewhere that is spiraling out of control.
I forgot to say I use Kaspersky Pure 3.0 for virus software and I have it performing a Full Scan, a Vulnerability scan and a Critical Areas scan every day. I also scanned the drive with Malware Bytes and it did not find any malware. Also I am running Win 8.1 - it came that way from Lenovo.

When I press Fn+F9, Wireless Radios Master Control will appear, but there's only WiFi icon and Bluetooth icon is missing (I installed all latest drivers for my model E520 1143-37G).
I have seen advices to reinstall Hotkey Features Integration Pack but here comes my second problem. This HFIP includes Lenovo Patch Utility 32&64 bit but it's old version (1.2.0.1), newer version is included in Power Manager and ThinkVantage Communication Utility (v1.3.0.9). That;s the thing I don't get at all...

I just bought a used Red E520-1143CTO in brand new condition, from someone who screwed up the OS (It had Windows 7 Home Prem 64). A lot of the drivers were missing and not working correctly. The restore partition is still there when I look in My Computer but when i reboot and press F11, I never get the option to access it. There was no Lenovo software installed to create a repair disk and of course, it didn't come with any software. Is there a way to access it?
I also have access to another E520 that is almost exactly the same (It just has the older i3 processor). I tried to create a repair disk from it and use it on this computer but it says the Windows versions are not compatible or the Repair software is not compatible with this version.
So I'm trying to figure out if there is an alternative way to access this restore partition. I've installed a company version of Windows 7 Enterprise 32-bit on this machine and I've got most of the drivers installed and it appears to be working fine. But I have three that have yellow exclaimation points:
1) Base System Device
2) SM Bus Controller
3) Unknown Device
I've been downloaded drivers from this site, but I can't can't figure out which drivers I need to clear this list. So, how to get it restored to factory default. If not, I'd like to know what drivers I need to clear this list. I want it to look like brand new because I was going to give it to someone as a gift. I just don't see the on screen prompts for the wifi button (doens't work), volume, and brightness like the other machine. I'd like to get all that working.

ThinkPad Edge, Win 7 Sp1. For the last month I have had a problem with the control key always down. Programs react as if the control key were pressed. MS Word 7 gives an error message that the control key is down and asks if I want to go to Safe Mode. I have had the keyboard replaced with no change. The computer has been thoroughly checked, all drivers, patches, software upgrades have been made by my Tech, and the Bios has been flashed.
Last week, I found a post on Google for Win XP where the poster had the same problems. The fix was to ensure that the Sticky Keys were turned off in Ease of Access on the Control Panel. I went to Ease of Access and turned off all of the selections, and the fix seemed to work. However, yesterday the problem reoccurred. I don't know if it is a problem with the motherboard, hardware, or with Windows. It appears that this problem affects more than one version of Windows.

I just received my new E545 and booted it up. I've noticed the CPU is quite hot and so ran some software tests. It is showing the CPU temp around 92 degree C / 196 degrees F.
The chip is an AMD A10-5750M. I take it the heat isn't normal. Should I be sending this back to warranty?

I am experiencing issues with my touchpad on my Thinkpad Edge AMD with 4 GB Ram.
Sometimes the touchpad will work and sometimes it will not respond. When I restart the computer, it will work but not for long. I have the up-to-date drivers which came with the machine. I just received my machine 2 days ago.

I just purchased the E540. Running Win 7.1. I have 2 WD 3.0 Passport drives plugged into a USB 3.0 hub. The 3.0 hub has the correct cable for 3.0. They are not being recognized as 3.0 devices (I get a message). I updated the USB 3.0 driver on lenovo's site and BIOS is set to auto.recognize. I have also tried the 3.0 option in the BIOS but that didn't do anything. I also tried using the drives without the hub in one of the 3.0 USB slots but that didn't do anything either.
I have checked the forum but what I found was possibly purchasing a 3.0 cable (not necessary - my cable is 3.0 compliant) but that was for a Wn 8 system or updating 3.0 device driver (done). So much for plug and play.

I just reinstalled windows 7 on my edge 13 (cause the system really slowed down), everything's working so far, expect the WLan Device. The network adapter (realtek RTL8168D/Familie-PCI-E-Gigabit-Ethernet-NIC) is properly detected, if i plug in a Lan cable I have got a connection.
I already tried this Lenovo Update tool, it installed some drivers and updates, but still no change. I already tried all Wifi drivers from lenovo homepage without success. Hitting the F9 Button didn't change a thing.

I've had several laptops but I am hating this one and is basically the Fn Keys and F# Key. I am pretty customed to use keys like F4(invoking word magic), F5 (update), Alt+F4 (closing windows)...
So, now I have to press Fn + F4 Keys, Fn + F5 Keys and Fn + Alt + F5 Keys....
So is there a way to continue pressing just F4 F5 and that's it?

Just a got a brand new Thinkpad 540-E. So far this CPU runs like a beast(with a new SSD installed). I have one minor issue though...
GOAL:: Make the F1-F12 keys function without having to press Fn first.
So I've tried the three tips I've come across online. Here is what happens:
1. BIOS(ThinkpadSetup): I only get the option to switch the Fn and Ctrl key. There are no option in my BIOS to do anything else with the keyboard/mouse settings.
2. Holding down the Fn key for 30 sec to 1 minute: Nothing happens. I even tried to do a three minute press and hold. I had a blast, but nothing came out of that neither.
3. Entering the keyboard settings in Win 7 manually: So I have no trouble entering the keyboard settings window, but mine looks extremely limited. In fact I see no options to do anything in there besides updating the driver.

I am planning to upgrade my RAM on my E420(1141CTO). It already has a 4 Gb on one slot. Couple of questions here.
1. What is the max RAM I can go upto on this E420 (Intel i3 2nd Gen) laptop.
2. As I have 4 GB on one slot can I put one 8Gb RAM (single module) on the other slot.
3. What brand of RAM I can use.
4. On this model can I fix another RAM myself easily or asking it the other way are the slots placed such that I can do it easily by merely oepning a couple of screws or do I have to tear everything apart.
5. Any other special considerations like about clock speed ?

With this laptop, the CPU usage rises significantly whenever the battery is charging. If I'm on running on battery power or it's fully charged, I don't have this problem. The CPU stays at 2-3% while browsing the internet, for example. But browsing the internet while the battery is charging will send the CPU up to 90-100%. It's not just browsing the internet, but any task, such as running Sony Vegas, using Skype, watching a movie, etc.
Again, this only happens while the battery is charging. Everything runs much, much slower. All power management settings are identical whether it be running on battery or charging with the AC adapter, so it's not that. I am also using the 65w power adapter that was supplied with the computer, and the adapter becomes very hot to the touch while charging.

I purchased a Edge E545 that came pre loaded with Win7 Pro 64. I created the Recovery disks for Win7 and used the Win 8 Disks to upgrade the OS. I have created a new NTFS partition on my hard drive and would like to install Win 7 to that partition. I have tried to load the recovery disks to install into that partition but I have not been successful; the boot disk won't even load. I downloaded the Win7 Pro 64 ISO to try and load it into that partition but the computer does not have the COA sticker under the battery like it's supposed to.
I have recovery disks that won't load at restart or cold boot and I have a perfectly good ISO that i don't have a COA to.

I just got a brand new Edge 335 with Windows 8 Pro 64 bit installed. It has 8 GB RAM, and AMD E2-2000 APU. I've had a couple of issues with this. One was that I couldn't turn on Bluetooth in Windows 8 (fixed by installing an older version of Thinkpad Hotkey features software). The other issue which is still unresolved is that of virtualization.
AMD virtualization is enabled in the BIOS. However, Windows 8 as well as the AMD virtualization tool both state it is turned off. I have, after searching these forums and the web, disabled it, cold booted the machine (removing battery), re-enabled it, cold booted again (also removed the battery). However, Windows just doesn't want to accept that it's enabled.
AMD virtualization and DEP were both enabled when I got the laptop from Lenovo. Is there anything else I need to turn on/ off?

My keyboard is Norwegian so there is a key called AltGr available which is used as a combinational key similar to shift. when I just press the key related to backslash ( it's '+') it works fine but when I want to type backslash (it's AltGr and '+' together) it does not work.

Lenovo thinkpad edge e531 - How to know charge fully?

I have a ThinkPad Edge 15. It had a charging problem from the day I purchased it. The people I bought it from sent it back to IBM/Lenovo who apparently tightened the area where the charging cord goes into the PC?
That did NOT fix the issue, so when I got my laptop back, I called LEnovo, they sent me a new battery (even though I told them the 'Power Manager' said the battery was in good condition) which did nothing. Then they sent me a new charging cord, again-nada. They sent me a box to send the laptop back to them. As I was figuring out how to put the laptop in the box, I looked over @ my PC, and lo and behold; the light that tells you if it is charging was shining!
Last night. I looked @ the charging icon; '15%, not charging'! Oops! Oh dear, not again! Went to power manager, everything is just fine. Checked all of my connections, same thing. I left the laptop plugged in. This morning as I look over @ the laptop & Guess WHAT! It was charging, the light was on! I turned it on...
