I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

EDIT NOTE : This post was move to the top of the page to assist Lenovo with an escalation. For all future post and comments, please continue posting in this thread. i have this issue too, but when i changed the option "intel virtual technology" to enabled in the bios configuration section, my laptop started at 3.2 ghz on battery, then i changed the power option from "high performance" to "power saving" mode, it was redused to 0.77, then i changed back to performance mode,it speeded up till max. it seamed problem was solved.  i am not sure what intel virtual technology is doing or related to this issue, but it's worked for me. i hope this helps. meh, after 3 restarts it's stuck at 0.77 again, i think we definetly need a bios update. Edit- After a quick search, i ve found that "intel virtual technology" doesn't related to this issue, and it' NOT THE SOLUTION.  problem still exists. Also, just fyi, some other brands of devices faced this issue over the inernet and all solved by bios update or board replacement.    EDIT NOTE : This post was move to the top of the page to assist Lenovo with an escalation.

A:Re: Lenovo Z510 CPU stuck at 0.77GHz

Hi! The CPU (i3-4000M) in my Z510 sometimes stuck at 0.77GHz. It doesn't matter if I set the performance to maximum in Windows and in Lenovo Energy Manager. It usually happens when the notebook is unplugged from AC but sometimes it happens on AC too. And also it doesn't matter if the computer is cold booted, restarted or waked up from sleep\hibernation. I have read about a lot of similar cases (just google on "stuck 0.77GHz").I'm using Windows 8.1 x64, the drivers ar up-to-date and all of the updates are installed. We are talking about a wold-wide problem since it is exists in other notebooks too. (e.g.: Asus) Is there any (un)known problem with the new Haswell processors\chipsets?What is the solution?

Hi there, I recently purchased a Thinkpad L450 and I'm pretty happy with it. What concerns me is that if I boot from battery my cpu clock speed is stuck at 0.77GHz. Plug and unplug the powercable solves this issue, but is not always an option. I have the latest BIOS update from 27.03.2015 and I always use the High-Performance-Mode (tried min: 100% cpu speed option too) Already read the regarding thread for the Z510: https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Re-Lenovo-Z510-CPU-stuck-at-0-77GHz/td-p/147006... Are there any infos on this issue for the L450? EDIT: It seems that I cant reproduce the "plug, unplug fix" anymore. Cable in = up to 2.7GHz, Cable out: 0,77GHz which is pretty unacceptable. Regards,Christian

My brother got a X240 with a regular 1TB HDD, and I'm looking to help him with upgrading to an internal SSD for the OS/Apps. I first thought it just used a regular mSATA, but it apparently uses a new style called M.2.
 
Unfortunately I can't seem to find any info on what's supported, how large can they be, etc...
 
My local computer store has this for M.2 in 512gb size, would this fit in the X240?

Howdy HiVolt,
 
I don't think that one will fit.  There are several different lengths of m.2 SSDs and the one in the X240 is 42mm.  The one you linked is longer than that.
 
Up until recently the highest capacity 42mm part was 128GB IIRC, but I think someone has come out with a 256GB 42mm unit.  [edit] I'm not able to verify that just now.  [more edit] Yes I am.  See post below.
 
Here's their compatibility list.  Please note I have no personal experience with this company.

I?m unsure if I?m doing the right thing here, never posted anything like this before. The X240 laptop I have was working yesterday, and I put it to sleep so I could continue working later. However now it won?t turn on at all, except the lights over the F1 key, F4 key, and Fn are on. It wasn?t plugged in, but this has never happened before. I?ve also taken out the battery in a myriad of different methods people have suggested online but there?s been no mention of the lights still on.  If if I could get some help, that?d be great. I don?t know much about computers.

Hello, In short, fn key does not work in lenovo x240 with latest bios update (2.35). I can swap fn and ctrl keys, and then function keys works via the ctrl key, but the fn key does not work as ctrl. I think this problem is OS independent (tried w10, w7, ubuntu). I have tried installing older bios for this model from the following page:https://support.lenovo.com/es/en/olddownloads/ds035950 But I can only install a few of the newest ones, as the older ones report that they are not compatibles with my system (though the readme says w7-w10 compatibility). No luck with any of the ones I could install. I also tried the hotkey features integration from here, no luck either:http://support.lenovo.com/es/en/downloads/ds029026  This question has been answered a gazillion times, but ill do it one more time as there is no solution posted anywhere.

My Thinkpad X240 only comes with an external battery pack, no internal.  I usually power down my laptop at the end of the day.  The following day it won't power on.  I have to remove and re-insert back the battery pack before it turns on. If I power down and leave the laptop for 2hrs it will power up without me having to remove and re-insert back the battery pack.  But if I leave the laptop powered down for more than 3hrs I have to do the process to turn it back on. The battery charges normally, I usually get 4hrs out of the 6 cell pack. I ran the Lenovo Solution Center Comprehensive Tests, no errors found.  I also did the rest button but it won't power on without going thru the process of battery removal.
