Lenovo IdeaPad L340 No post

Greetings all knowing tech types and otherwise IT pros,


I think I know the answer to this, but Im looking for either an alternate solution (or confirmation of my own thought process) for an old deadheadlike me to get my son's laptop back to working order.


As the story goes:

The L340 received notification of a bios f/w update, and the update was started however the power on the battery was not sufficient to sustain the update timeframe and it lost power sometime during the update process. The L340 power supply was then plugged in and the power LED comes on when depressing the power btn, but no screen activity is verified (screen is black no backlight), no beep (Im not sure if it ever beeped on post), I can hear the system fan come on but nothing happens after that other than normalized heat from the system if we leave it on for anytime thereafter.


We have tried:

From powered off - pressing power & immediately tapping F2 and combo Fn+F2 for approx 15 seconds = no dice

Allowing the unit to self-power off without power adapter (drain battery/ flea pwr), apply power adapter + power btn = same result 


L340 does not appear to have NOVO btn and battery is not removeable


Does anyone have any suggestions for system recovery or confirmation of taping nickle to it and tossing in nearest body of water? (Kidding I'd never do that without making every effort to get the data recovered to another device) Im not sure if its under warranty (checking on that now) still but I've considered taking it to authorized repair location, but thought I would try the community forum first.


Thanks for any replies Smiley Happy

Hi @Deadhead_73 ,


Welcome to Community Forums!


We appreciate the efforts that you tried to get the computer fixed.

Try to look for the Novo Button on the left side of the laptop. (Page 5 of the User Guide Manual )

You can try the troubleshooting steps provided on this article regarding No Post, No Display or No Video .

Just follow the step by step troubleshooting to isolate the issue if it's hardware or software.

If it leads to repair, please call Tech Support for repair options if unit is still under warranty.


Give us an update on how it goes.

Hi @Deadhead_73


Welcome to Community Forums!


Since you mentioned its a No Post I assume that the Caps Lock LED or the Num Lock LED is not responding when you hit these buttons.


Perform a power drain Desktop

  1. Unplug the power cable from the wall outlet.
  2. Hold down the power button for at least 15 seconds.
  3. Reconnect the power cable and try turning it back on
Access BIOS​ through the Novo button

As shown on the IdeaPad L340 User Guide ( page 5-6 ) as shown on the photo below the NOVO Button should be located on the left side ( see number 8 on photo below for your reference ).

Or Access BIOS through F1 ( Pressing power & immediately tapping F1 )


Once successfully accessed BIOS hit F9/Fn+F9 (YES) to restore BIOS to defaults then hit F10/Fn+F10 (YES) to save changes made.


Try turning on your computer without the MEMORY/ RAM.


Try Reseating (process of removing from their slots and correctly placing them back into place ) the following:




CMOS Battery





Let us know how it goes
