Preferred Solution: T450s Can't Boot From USB

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.)

UPDATE: Finally finally managed to change boot order... still refuses to boot from new M.2 unless I use the F12 boot menu.I even excluded the old  one from the boot menu... now it just launches into repair mode. Why will it boot from the new M.2 (which is now the C drive) just fine with the F12, but not just by turning it on?I've installed a new 256 M.2. The system insists on booting off the old 16BG drive (which had Win10 pre-installed), even though I've made the new one the C drive. The old one is now E, and unless I used the F12 boot menu, it always boots from the 16 GB M.2.I migrated Win10, and it will boot fine... if I use the boot menu. BUT... I've changed the 16 GB drive to E:, and the new one to C. Why, why, why does it keep insisting on booting from the now E: drive? I even deleted files off it, now it just gets errors and I have to use the F12 boot menu every time to boot from the C: drive.I've searched for hours... and hours... for a way to change the boot order. But Lenovo seems to have (malevelontly, because they hate me) removed that menu from the BIOS. How the heck do I change this? Please?

Hello, My T540s (which just ran out of warranty ...) has a very weird issue : When I try to boot (clicking the power button), the fan starts turning, the keyboard's backlight turns on, but ... a second later (even before the Thinkpad logo shows up), the whole computer crashes and shuts down !Where it gets even more special is that from time to time (1 out of 1000) the computer boots normally, although giving me this warning :Secure Flash Authentification FailedCapsule Data is invalid_ I'm kind of lost right now, really don't know how to get that fixed. My friends think that my motherboard needs to be changed, but I really want to be sure before buying a new one (very expensive). I suspect a bug in the BIOS (recent update failed ?) ... What do you think ? Does anyone have or had the same problem ? Thanks for helping, Best, Sylvain E.K.  PS: Running Win7 64bit

A:T450s random crashes on boot

One possibility: damaged USB port.  This was known to happen on some older T-series laptops.  Bent USB port pins would short power, causing the quick shutdown.
 
It's not likely in your case (would be 1000 failures out of 1000...) but worth a quick check.

My year-and-a-half old T450s stopped booting up. Yesterday I was prompted for a Windows update and restarted the machine, as usual. After the update, I'm able to turn it on but it wont boot up. It shows the initial screen, with the "Lenovo" logo and won't proceed beyond.I tried taking out one battery and then holding the on/off button for 30 seconds, and also the emergency reset on the bottom, but neither changed anything. It simply won't go beyond the initial screen. Does anyone have any thoughts? Thanks in advance.

I think you are experiencing the same issue I have. If you notice after the Lenovo boot logo the display still stays on its just black, what it appears to be for me is a video failure after trying to update to windows 10 anniversary update. Try plugging in an external monitor and see if you get display, I did in my case.  Remove your hard drive and restart the PC, this should get the bios working again, go into your bios and disable secure boot so you can boot to a USB. Create a bootable USB 3.0 using a USB3.0 drive (formatted to NTFS) from Microsoft's site - https://www.microsoft.com/en-us/software-download/windows10/ Then goto repair my computer and choose rollback update, this will get you running again.  I have a p50 with Nvidia M1000M dedicated graphics, so I am still trying to figure out if this is a driver issue.

I have a T450S that is a few months old. It has worked fine until just the other day when it would not turn on. When I push the power button, the green LED flashes three times. Then, the LEDs on the F1, F4, and Fn keys come on for several seconds and go off. Here's what I've tried:- Charging for an extended period.- Removing the battery for an extended period.- Removing the battery and holding the power button for 60 seconds.- Pressing the button in the emergency reset hole. Nothing has made any difference.

According to this website: http://www.pugetsystems.com/labs/articles/Overview-of-M-2-SSDs-586/m.2 slot comes in different flavors (SATA III, PCI-E 2.0 x2, PCI-E 2.0 x4 and PCI-E 3.0 x4) I would like to know what is the supported protocols for the T450s laptop. I'm asking this questions becauce I would like to buy a m.2 SSD disk to replace the "too small" 16GB that I have and I would like to know if it's worthwhile buying the Samsung SM951 that supports PCI-E 3.0 x4. Thank you.

A:T450s m.2 SSD

Good day and welcome to the community.
 
Apologies that I can't answer the SATA vs PCI-E portion of your question with any certainty. I can say, though, that the SM951 won't fit physically in your machine. That SSD is a 22x80mm form factor (2280) while your machine takes the 22x42 form factor (2242).
 
Please have a look at your hardware manual:
http://download.lenovo.com/pccbbs/mobiles_pdf/t450s_hmm_en_sp40g54937.pdf
where manual page 66 describes removal / installation.
 
Then, have a look at the FRU BOM:
http://download.lenovo.com/parts/ThinkPad/t450s_frubom_20150126.pdf
and on the last page you'll see the only factory part listed is the 16GB M.2 2242 SSD normally used for caching (I believe).
 
You should still be able to install a higher capacity 2242 M.2 SSD in that slot, though. The largest M.2 2242 SSD I've seen is also 256GB, but I haven't searched exhaustively.
 
Hope this helps a bit.
Regards.

I have a T450S laptop. It came with 8 GB of RAM (4 on the board and 4 GB SO-DIMM). I replaced the SO-DIMM with a Crucial 16GB one. When I look at the system information, it indicates that I have all 20 GB of RAM available. I recently asked the computer to do a relatively big, but not that big, processing job that took a long time (14 minutes). While it was crunching, I checked the resource monitor and it indicated that only 3.9 GB of the RAM were being used and that  ~16GB were available - but the extra 16 wasn't being used, just sitting there being available. When the processing completed, the resource monitor still says that 3.5 GB are being used with "regular" computing - so basically, nothing was different with the big job compared to just ordinary tasks. How do I make the computer use all of the memory that it has? I've looked all over for some sort of setting.?

Hello,
I am experiencing cpu/coil whine issue in my brand new T450s. Any ideas? I read the issue is caused by low quality capacitors on the motherboard. Does anyone else experience this issue on the new T450s? Should I contact the Repair center? Noise is definitely related to the cpu power consumption, because when the cpu is working it is not noticeable, I have to put my ear on the keyboard to hear it, but when the cpu is idle the buzzing is very annoying.

A:Upgrading T450s w7 to w10

1) The T450s sold with windows10, did they have the Lenovo features?Most of ThinkVantage applications were discontinued after Win7, as newer Windows versions have many build in features, which make additional applications unnecessary. Pre-installed Win10 Pro came with additional theme, some logos, (sometimes) power plan and four or five Lenovo apps (most of them are no longer developed).2) Is it possible in this case, to reinstall a recovery T450s in w10 on this laptop?If you made a copy of Windows 7 Pro recovery, then there's no problem to reinstall it again.

I accidentally closed my T450S without turning it off last night and went to sleep. Today it won't turn on. When I plug in the charger the power button blinks 3 times. I have work vital to my job and my studies that I must retrieve soon. The laptop is 9 months old, but the warranty is invalid because I live overseas and I can't ship it to the US for repairs. I have files I need Monday morning or I will fail my courses, which means I also lose my job. I have some of it backed up, but the finished product was a file too large for my google drive and I just bought a new external hard drive to back up this korning. I have tried:1. Booting without the battery2. The emergency reset button3. Removing the internal and external batteries and booting4. Draining the battery by holding the power button then booting with no battery5. Hitting the power button 10 times then holding for a minute then booting6. Removing the RAM, draining the power, replacing the ram, then booting with no battery7. Unplugging and replugging the connector between the charger and the motherboard8. Putting the whole thing back together and letting it sit on the charger for an hour in the hope that all this stuff did something and now it just needs to charge. Everything I tried left me with the same result. 3 blinks of the power button when plugged in, and no other response to anything else. Is there any way of repairing this giant waste of money sitting on my desk?

This Lenovo Forum thread has a reply form a Lenovo moderator that states that the T450s has 4GB memory soldered to systemboard and one 204-pin SO-DIMM socket, so on your system the SO-DIMM slot probably has a 4GB SO-DIMM installed.     From what he states, if you have a 5th generation  CPU you could go as high as 20GB if you added a single 16GB SO-DIMM, but they are a bit pricey.  Crucial 8GB DDR3L-1600 SODIMM  - $46.99- DDR3L PC3L-12800 ?

As for the function keys, press FN + Esc once to activate FN Lock and switch the FN functions. The TrackPoint sits indeed lower, in order to protect the screen (as on older ThinkPads, the TrackPoint would often touch the screen when the lid was closed). Its not recommended to use the older, higher caps. Rather get used to the lower caps.

I just wanted to post a problem I had with my T450s, and the way I solved the issue. I couldn't find a solution online, so I am going to share how I fixed it, in case somebody else has this issue. PROBLEM:I had let the battery run all the way down, and when I connected the AC charger next, the laptop would not power on. The power button would blink green 3 times when I connected the charger, but pressing it down would not turn on the machine. I tried holding down the power button for 30 seconds, tried turning it on with and without the external battery. Nothing worked. SOLUTION:I figured that a battery pull would fix the issue, but pulling the external battery was not enough. The internal battery must also be disconnected. This process is laid out in the following video explaining how to replace the backup battery: https://www.youtube.com/watch?v=CJtH5S7RURo You do not need to replace the backup battery itself, just open the computer, unplug as directed, and then plug it right back in. My computer powered on immediately. I needed to reset the Date/Time in the BIOS, and then it booted up just fine Side note: I called Lenovo techinal support, and after describing the problem, they immediately decided to send me a box to ship the laptop to them for repairs.

Hi everyone.Unfortunately looking for advice for my t450s. I had it running last night, transferring items from an SD card onto a network drive. It was plugged into the AC. I just left it to transfer as it was around 20gb and I saw the keyboard flash in the corner of my eye and got a blue screen saying "page fault in non paged area". The computer restarted several times and resulted in the same blue screen and same fault. It tried to go through automatic recovery but that failed with a blue screen and the same fault. I just left the computer for 10 minutes hoping it would sort itself out, but it didn't, just looping with various blue screen faults (IRQL less or not equal, uxc01000.sys failure - and others I didn't manage to get a photo of)  I dug out my Lenovo recovery discs, the same fault when booting from CD, after 10 seconds or so "page fault in non paged area".  So from there I have tried disabling various items in the BIOS such as trackpad and removing all my USB and SD card etc. Not every time I turned it on it had the same fault, sometimes would hang on POST, sometimes on loading windows (10) sometimes fan on full speed and sometimes fan off. And now, when I turn the laptop on nothing happens. The power light comes on, sometimes the fan goes to full speed sometimes it does not but nothing happens after that.

A:30-day Standby with Windows 10 - t450s

30-Day standby is completely broken on Win10.  There are actually 2 issues:

the 3-hour timer to go into Deep Sleep doesn't work - the reason is because Windows 10 sets it's own timers which conflicts with 30-day Standby
You might not be able to resume from Deep Sleep - due to a BIOS bug.  I don't have a fix date yet.

 
Based on your description, you are seeing both issues.  I recommend that you disable Intel Rapid Start Technology in BIOS, and move on.
 
Win10 hibernate/resume is actually pretty good, so I recommend setting up OS timer to go to hibernate after 3 hours (which will give you the same effect as 30-day standby, but without taking up space for a special hibernation partition on your SSD).  The reason why 30-Day standby existed was because hibernate/resume in Win7 and Win8 was too slow. MS improved it in Win8.1 and Win10 is a lot better.

My new t450s has worked perfectly so far, except for one occasional, and very frustrating, hitch. At times, usually when I just turn on the laptop after having shut it down, the monitor of my laptop will begin flickering. This flickering is like horizontal lines flashing across the screen and distorting the image. After a short time of this, the screen will usually black out and what looks like a barcode will appear on the screen so that anything I was working on will not be visible. I have found that I can temporarily fix this by wiggling the screen (but then the flickering returns soon after) or be restarting the laptop (which gives me about a day of smooth running but time after time the flickering has returned eventually). Does anybody have a similar issue? Any way I can fix this without mailing the laptop in? I leave for school in a few weeks and I would prefer to have my laptop going in. Thanks for any help

I have a Lenovo T450S.  It came with Windows 7 installed, but I did a fresh install of Windows 8.1.  Everything seems to be working fine, except I have no sound at all.  Nothing from the speakers, and nothing if I plug headphones into the jack.  This is the list of things I've tried up to this point. - Uninstalling from Device Manager and letting Windows reinstall- Download drivers to reinstall manually- Attempted to set default audio device in Control Panel (Says no devices installed, even when showing disabled devices)- Windows Updates (100% up to date)- Scan/Updates through Lenovo Solution Center- Update BIOS- Update Chipset Realtek HD Audio Manager doesn't show up in the Control Panel at all.  The Lenovo Solutions Center shows that the HD Audio Controller is disabled, but going into the Device Manager shows that it's enabled, but has this error message: "A driver (service) for this device has been disabled.  An alternate driver may be providing functionality. (Code 32)" I'm at a loss at this point as to what to try next.  Taking any and all suggestions.  Thanks. Make/Model - Lenovo T450SOS - Windows 8.1Product Name - 20BX001AUS

Welcome Lloyd12341. Could you access the BIOS (Press F1 when the laptop is booted up - POST), and check if the HD Audio is enabled? 2. If it is enabled, reload optimized default and restart. (Remember to change boot to UEFI if you have changed to it before fresh installing of Windows 8.1)3. Where do you download the driver? From Lenovo Support or Realtek Support Web?

I got my new T470p last week but I'm having troubles with the 2560x1440 screen. The resolution is just too high for me! Scaling up the fonts, icons, etc. works ok, but I'm also using a lot of different external screens and projectors, and then everything is just way too big. It's really frustrating. My previous model was a T450s, with the 1920x1080 screen, which is perfect. Now I was wondering, would it be possible to swap the two screens? From the platform specifications, it seems they have the same dimensions (14.0" 355mm). Is this completely insane or might it work? I thought I'd ask before opening them...

Hi,I have ThinkPad T450s.I usually use it with its power cord plugged in.When I'm done working, I close the lid, take out the power cord, and make sure it's asleep (the red lamp is slowly blinking). Alternatively, I choose sleep from the Win10 menu.When I take it out of my bag after a few hours, it's very hot and the battery is almost empty.Why does it happen?Is there a way to keep it asleep?I'd really appreciate your help.Anna

Good day.
 
I believe the panel is LED-lit, therefore no inverter. There is no mention of an inverter that I can find in the HMM, either: https://download.lenovo.com/pccbbs/mobiles_pdf/t450s_hmm_en_sp40g54937_01.pdf

Dear Lenovo forums,We have during the last few months experienced some issues with the display of the Lenovo T450s PC. The issue concerns that the display stops updating while the user is typing or watching a video, but "resumes" displaying "live" whenever the mouse is touched. We've tried updating different drivers (power management, display drivers, onscreen display, etc.) but without any luck. The issue is not easily re-created, and can occur at any time - no specific moment or occasion. Below is a summarize of our observations:- Can sometimes be resolved by plugin in a power supply.- Can sometimes be resolved by closing down a few applications.- Can sometimes be activated by visiting dr.dk in IE- Only the T450s - the x250 or T460s has no problem- Not able to determine if it is a certain model of the T450s As you can see, we have no clear idea of what causes the issue, but are in dire need for a fix as this is driving our users mad.

As I understand, hardware fde works by using a media encryption key that is stored in the disc controller.  Access to this key is controlled by a key encryption key which the user should be able to set.  (Without setting this key, fde is pointless as the drive will boot without any user intervention). How does one set the key encryption key on the T450S?  And can it be configured so the key has to be re-entered after the wakes from sleep or hibernation, as well as at boot time. Thanks,

I just got it today, after everything was set up, I started to use it. Soon after that a message bumped out and told me tthat there're important updates, and I chose to update them. Then the laptop shut down automatically, it made a sound after the screen became black and it can't turn on anyway. I tried press the power button, it made 5 short sounds and didn't have any other reactions. The green light and the red light on the "i" of Thinkpad keep flashing in a low frequency. The only thing I have downloaded to this new laptopThe only thing I have downloaded on this new laptop was google chrome. I have no idea what happened.... Can someone help?

Hello and welcome,
 
Sorry to hear about this.  There's a post just below yours where a member reports a similar-sounding problem.

They were able to fix things by using the emergency reset hole on the bottom of the laptop.  See pages 6 and 7 of the (English) User Guide - ThinkPad T450s

Introduction The ThinkPad T450s is one of the best new ultrabooks. While it's not as thin as some, it's still quite compact, and much easier to service than thinner machines, and the Full HD IPS screen is a standout feature.This review is based on a production ThinkPad T450s, Machine Type 20BX, Product ID 20BXCTO1WW. Intel Core i7-5600U ProcessorWindows 8.1 Pro 6414.0" FHD (1920 x 1080)720p HD CameraIntel HD Graphics 55004 GB DDR3L - SDRAM 1600MHz BaseFingerprint Reader500GB Hard Disk Drive, 7200rpm, 2.5"ThinkPad Battery 3 cell Li-Polymer (23.2Whr) FrontThinkPad Battery 3 cell Li-Polymer (23.2Whr) RearCountry Pack 45W AC adapter United States (2pin)Intel 7265 AC/B/G/N Dual Band Wireless + Bluetooth Version 4.0After receipt: 4 GB Samsung SO-DIMM was installedHard disk was replaced with 1 TB Samsung 850 EVO SSD.ConstructionQuality of T450s construction is not up to old ThinkPad standards, with some obvious cheapening, but is still pretty good.

Hi guys, I've had the Lenovo T450S since January this year.  It has been plagued with touchpad problems.  I was getting constant popups of all kinds from translation requests to research requests, to copy/paste types.  I finally convinced Lenovo to replace the laptop in June.  Their tech said it was a HW problem. The replacement was fine for a couple of weeks, then right click type popups started to appear, MORE and MORE frequently.  I switched to Windows 10, hoping that would do the trick. NO!   I've had our IT guy working on it, no joy. I've reset the touchpad settings to be as insensitive as possible. m Surely, I'm not the only one who has this problem.  Just about every time I left click, and frequently when I'm in the middle of typing, a dialog screen pops up.  I've been using laptops for 30 + years and have never had this kind of problem.  Anyone had this experience? Thank you

I purchased my Thinkpad 450S directly from Lenovo website and received it on January 4, 2016.  Two weeks later it totally crashed and would not even start up in safe mode.  Received a USB recovery device.  Started to recover and then crashed.  Could not get it to work.  Called support and they sent a box out for me to send it back for repairs.  Now a part is on back order.  Here's my question.  Why don't they just send me a new one since obviously I received a defective one and be done with it?  I own my own business and this is killing me right now.  My HP laptop is barely holding on.  This is the busiest time of year for me and I am running out of patience.  Has anyone ever had this type of experience?  Who do I need to talk to at Lenovo to get this resolved?  The support personnel can only do so much and I am not really upset with them.  I am thinking I should have gone back to HP.  Feeling frustrated.
