Thanks for your time,
I did use the method mentioned even if it were for another model and another Error.
Unfortunately it didn't work.

Does it take 5 minutes to display the Lenovo splash screen, or do you see a chasing circle for 5 minutes before the OS sign on screen shows up.

Usually if the Splash Screen shows up then you get the spinning circle of dots, it means the OS is having some issues loading into the system. This could be from several issues, the most common is a failing hard disk drive.

If you can, boot up the system (even if slow) and back up your important files immediately to a USB Drive or Cloud account. Once completed you can safely run diagnostics on the hard disk drive (manufacture - Seagate, WD, Hitachi etc...) and see if it comes back with errors.

If you get errors, then I would suggest replacing the drive with a new one. Remember, make sure you have your recovery disks made, a fresh back up of your user data (pictures, documents, music etc..) before you replace the drive.

Good luck.

Thanks for the tip,
but the problem is in bios, i changed the HDD
and used a another OS,
still the problem is the bios is too slow,
now the bios takes 10 min to give the lenove screen , and WIN10 boots in 2 min
i tried several hardware changes, but the issue is in the Bios firmware, and i cant downgrade or overwrite it !!!!!!!!!!!

Have you tried the power drian solution yet?

 

If not - it is simple....

 

1.  power off system, remove battery and AC power adapter.

2. press and hold down the power button for 30 seconds

3. replace battery, connect AC power adapter.

4. boot up system using "novo" button,. enter BIOS

5. Set defaults in BIOS - might be the F9 key, check the promts

6. Save and exit BIOS - system will restart.

 

If this helps restore peformance let us know.
