My screen is frozen on 'Information' when in BIOS. The arrow keys are not responding when in BIOS due to this freeze. Function key and F1 F2 etc not responding. I need to access something in BIOSwas attempting to look at something with BIOS. I switched it off and on, same issue persisting. It was my first attempt at accessing the BIOS.
Windows 8.1 is working normally though, just the BIOS frozen. I had to switch off the laptop and power up again to access windows. Thank you in advance.
BIOS version 9dcn79ww(v2.00)

My Lenovo B50 upon restarts occasionally remains on the Lenovo logo without launching windows 8.1. When it does this I turn the power off and on then it's fine, windows 8.1 starts up.
Why does my screen remain on Lenovo logo permanently on restarts and how can I stop this? Thanks in advance.

Hi lenovoman123 ,
Welcome to the Community Forums.
BIOS screen is a confirmation that the system was successful on power on self test and at the part that it should be functional on the BIOS (arrow keys able to move ) would question the mahines integrity keeping the POST condition.
Would this be the same as described on your
Do you have the machine number (keep the SN confidential from the sticker or check it here ) of the computer to check specifically on other details?
If you shut down the pc after using it , would it goes stuck in the BIOS ?
Any difference when you shut it down with battery alone ? while connected to ac charger?
This is to isolate any issue regarding power for the other devices as it may also relates providing it to the GPU.
Would you still have active warranty on the system? You may check it here.
It may need isolation with observing the BIOS without the harddrive , testing each ram one at a time.
Update us how things go.

Hi spidey 101,
Model name: 20384
Intel i5-42104 cpu 1.7ghz
BIOS version 9DCN79WW (V2.00)
EC Version 9DEC19WW (V2.00) <-----what is an EC version anyway?
Insydell20 Setup Utility Rev.3.7
To answer you questions:
Spidey Q:If you shut down the pc after using it , would it goes stuck in the BIOS ?
A: If I'm in BIOS and I press the power off, the laptop switches off (power's off).
If I'm in windows 8.1 I click shut down, it shuts down properly
Spidey Q:Any difference when you shut it down with battery alone ? while connected to ac charger?
A: No to both questions. Tired with and without battery, no difference
Spidey Q: It may need isolation with observing the BIOS without the harddrive , testing each ram one at a time.
A: How do I remove the hard drive? I only see the DVD which seems to slip out easily.
I think I may need to unscrew the back to take out the HD?
Spidey Q: BIOS screen is a confirmation that the system was successful on power on self test and at the part that it should be functional on the BIOS (arrow keys able to move ) would question the mahines integrity keeping the POST condition.
A: You will not believe this but as I was typing this, the laptop switched off. I had to press the power button on to start it up again. So you may be right in that there is something with the POST. That has never happened before (as far as I can recall).
Questions to forum (you):
1. I will need to unscrew the back of the laptop to take out and test without the hard drive and ram;which tools do I use to unscrew the little tiny screws to do the test on the ram and hard drive? Can you be specific and give the the screwdriver size please so I can go buy it. Are they video's on this?
Not sure what to do now. I still need to access the BIOS to do something there.
Thanks in advance.

Spidey: Would this be the same as described on your other post?
A: No. This has got to do with pressing F2 then getting into BIOS to only see BIOS is frozen of its own accord.
The other question relates to from within windows 8.1 OS, I click restart, and the laptop attempts to restart and but remains on the Lenovo logo intro forever without windows 8.1 OS restarting.All I see is the Lenovo logo. I press the power button off and on to access windows again. In other words restart from windows doesn't work properly. Not sure why the Moderator merged these two different questions.

Hi lenovoman123 ,
The restart issue within Windows 8 may not be just a software program issue but the entire start up , port-boot sequence . To separete the two sides of the laptop ( hardware versus software) removing the harddrive and then accessing the BIOS would eliminate attempts to fast boot to Windows. Once the harddrive is removed , go to BIOS and see if the arrow keys allow you to move.
You may also want to have it checked further in a service center if you need tools and skill if necessary or take time to review these links for the guide:
Hardware manual on hdd removal (screw details included page 37)
Service training video for additional guide
To check within Windows for further evaluation :

When I was in BIOS and it froze I got this error message:
Question value mismatch with Option value Re-enter password
To get rid of it I powered off the computer, and then went into BIOS this time without issue.
What was the error message about?

Hi lenovoman123 ,
Key mismatch error to current value you have may cause of the error.
I would rather keep out of the BIOS for a now as to stay with a working computer whithout endangering bricking the machine. You may try checking with it service centers first as they may need to use speecific tools to carefully reset the firmware if needed.
