Preferred Solution: Lenovo X240 does not turn on

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.)

Hello, so I have a Lenovo think pad x240 as issued by my high school and I was using it last night and tried to power down by pressing the power button as I was in a rush but that did not work so I shut it down normally and now I am trying to turn it on and pressing the power button is not working, it definately has battery because I plugged it in overnight so I think the power button may be faulty, I have only had the laptop for 2 years. And yes I have tried the "secret code" trick but that does not work - presumably because my laptop also has an internal battery.I need help asap!!!!! Thanks in advance

A:Lenovo X240 Won't turn on

Hi nstock98,
 
Welcome to Lenovo Forums!
 
Kindly request you to try with the below given troubleshooting steps.
Remove the battery and AC adapter
Remove the hard drive and wlan/wwcan cards
Remove both RAM modules
Re attach the AC adapter and boot
If you don't hear a series of loud beeps it probably means a hardware issue.
 
Please let me know whether the above steps helped you.          
Thank you, have a good day.

Estimados,Mi Notebook Lenovo X240 hace unos meses derepente luego de modo sleep y abrir el la pantalla no prendió. La solución parcial que encontré fue desconectar y reconectar la batería.A veces cuando enciende es como si ubiera estado en modo sleep y otras veces es como si se ubiera reiniciado. Esto es totalmente al azar. He leido que hay una batería interna, será eso? Espero que me puedan ayudar. Saludos,

I have a Lenovo Thinkpad X240 that suddenly turned off whilst I was using it. It was charging at the time, and I'm fairly certain that the laptop itself didn't overheat. I've tried disconnecting the battery and ac adapter, holding the power button, connecting them back on and pressing the power button but nothing. It would be great if someone could give me some help, thanks.

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.

Hi everybody, yesterday my X240 didn't wake up from sleep properly (LED backlight went on, nothing else happened), so I tried to restart it. When I hit the power button, the following happens:The power button LED and the Fn key LED light up and stay on.The red F1 and F4 LEDs briefly light up, as well as the keyboard backlight, but those go out after less than a second.I can hear some faint noise, the fan probably.Screen stays dark, no backlight. Connecting an external monitor does not help. I have tried to remove the power supply and external battery, pressed the Power button for 30 seconds, hit the emergency reset button, no results. Any ideas?

Hello,I'm sitting here absolutely confounded. I just reinstalled Windows on my x240 and decided that, while I was at it, I might as well remove my BIOS password, as I am no longer in school. I primarily use my laptop at home, so a password isn't really necessary.I go into the BIOS and straight to the security tab. I start disabling everything that is enabled and related to Supervisor password, Boot-up password, Start-up password and so forth. At one point, I am prompted to type in my current password and next to fill in my new password and to type it in once more. Being somewhat familiar with how unintuitive a BIOS can be, I leave the fields where I have to type in my new password blank, thinking that the BIOS will then assume that I want to have no password. I leave the fields empty and hit ENTER. It accepts this for some reason. I get a system halt for some reason and my laptop reboots. I am then prompted to type in my BIOS password as per usual, but it won't accept the password I usually use, which means there's an active password, but no longer the one that I've set prior to this. I try different passwords, I try just hitting ENTER, but no luck.I am locked out of my laptop and every Google result even remotely related to my issue suggests that I have to purchase a new motherboard for my x240. Really?I did not set a new password, I left the fields BLANK and hit ENTER. I have no idea what the password could be.I figured perhaps the BIOS password reverts to a prior password,... Read more

A:Lenovo x240 LOCKED OUT

Ok, this is embarassing but it might be something to learn from.I just remembered the very first BIOS password I set. I tried it, and it worked. Leaving the fields blank caused my BIOS to revert to the earliest password, which is the password I set prior to the one I am using now.Either that, or my supervisor password and my start-up password were different.Anyway, feel free to mark my thread as resolved or just delete it.

Hi, I'm having problems with my X240. I'm running Windows 10. When I shut down the computer, it stays off for 2seconds and then boots back up. This only happens on battery power, when connected to AC the computer shuts down fine and stays off, BUT if I remove AC it boots up in 1 second.. This is really weird.I've disabled the "Turn on fast startup" option and had a look at the options in BIOS but no luck..BIOS version GIET87WW (2.37). Thanks in advance,Mart

I recently purchased a used ThinkPad X240 and the original owner removed the HDD. I didn't believe it would be a problem since I have a 500GB SDD. He instructed me that he had installed 8GB of ram and had removed the original 4GB, again... didn't believe it would be a problem. Turned the system on with a Live USB of Linux and was not pleased to hear three beeps twice, followed by a single beep. I opened the unit and removed the 8GB stick. Received the same sounds... memory issue. I read the memory and it was 8GB DDR3 1600MHz 1.5V. I called the seller and said this is the wrong memory. These units require DDR3L (Low Voltage) 1.35V memory. He said he was unaware and it's all he has. I went and purchased Micron 8GB DDR3L 1.35V. Installed it and no more beeps. Great! Problem... no video either. Pressing power the keyboard lights up, fan spins and power button plus I on ThinkPad lights up... then keyboard lights go out, fan stops and that's all she wrote. About 1 minute and the green light on power and red light on I goes out. I tried completely discharing the unit, removed CMOS, Internal and External batteries and then held down power button for a minute or two. Same results. Tried an external Lenovo IPS monitor, and nothing... just black screen. Tried F1 repeatedly and nothing also... just black screen. Any ideas would be appreciated, thank you.

Hi, My lenovo X-240 has recently developed the following 2 issues since i upgraded the OS to windows 10 1) The display sometimes develops a vertical band with some visible lines and sometimes i only get some vertical bands in various colours without any display. This problem only started after installing Windows 10. Before that there was absolutely no issue. Please advise if this is a driver issue or how i can fix it. Today also it started with those bands and then the display has come normally and this behaviour is random. 2) The windows 10 keeps getting corrupted. I suddenly get the blue screen stating boot has failed and then i have to re-install windows, nothing else works. Many thanks for your help.

Hi, i'm experimenting problems with graphic card driver. When i install the driver (both the Lenovo suggested one and the Intel one), the screen become black and i can listen the sound of a disconnected device. Then, after every boot, i can't see anything on the display. I installed windows from zero and i haven't installed any other third party software, the only operation i've done after the installation is the Windows' update and Lenovo's drivers update. I tried also to install graphic card driver in safeboot mode, and the installation completes, thus i think the problem depends on conflicts between drivers. I also tried to install old Intel driver, but the problem persists. The first time it happend was in June, during a Windows' update. After that, the only "solution" i found to see the screen is to restore the Microsoft basic driver. I can't figure out if the problem depends on Windows or on Lenovo's drivers. Any solution?Thank you.

Hi,The display on my 3+ year (4 month past warranty) old Lenovo X240 is starting to have problems (12.5" HD (1366 x 768) LED Backlit AntiGlare IPS Display, Intel HD Graphics 4400). It boots fine, but every once in a while I?m using the system, the image will start to fade to white (actually more like light gray), i.e., the current image becomes more and more latent, while the sound continues. I snapped three pictures while I was watching an episode of Bosch when this happened again this morning. The screen will eventually blank, and I?ve notice a while (somewhat jittering line) at the bottom of the screen while this is happening. (See images at bottom)If I close the lid and then open it, it will generally reset itself, but it?s been happening more frequently late, though there?s no pattern and I can?t replicate it at will (with an external monitor for example). Again, never have this problem during boot up.Three quick questions:1. Has anyone come across this? Any idea what this might be?2. If so, is this easily (ie cheaply) fixable? I like the laptop and would continue using it otherwise.3. If not, what would be an equivalent laptop in place you could recommend, Lenovo or otherwise. It looks like there?s a Lenovo X270 now ? would that be the one to consider? Any non-Lenovo laptops I should consider? FWIW, I?ve only had Thinkpads in the past (T23 if even earlier), I program and like the dedicated PgUp/PgDn,Home/End and arrow keys for editing purposes.Thank...

This laptop won't turn on screen does not even flicker. The power light does come on and the battery does charge. I know this because the light blicks orange if it is charging and eventually goes back to white when complete. I have replaced the mother board and the lcd with absolutely no change. I have removed battery power over night and no change. I've removed both battery and cmos battery overnight and no change. The only reaction other than the power indicator light and charging lights is that the pc will beep when the power adapter plug is inserted or removed. Also, I cannot turn the power off. If i deprees the power button for about six seconds it wil turn off and turn right back on again anfter i release it.
