Could be bad RAM, motherboard, hard drive, etc. Any beeps during startup? They would tell you what is wrong (with a Google search).

Take it to the shop. Your Motherboard has a problem.

bios battery dead?
test booting with linux CD / USB stick

remove the small part of the back cover and press the reset button near the sim card slot.

When computer freeze press tab button, and see if there is any reaction/ if yes there should be some information what is wrong. Disconnect hard drive and check if computer pass the blue screen with logo. I think that it will be hard drive. If there is any chance try to turn on pc from cd bootable linux, with disconnected hard drive

Hello. It appears that you have a problem with your motherboard or the BIOS on your motherboard. When you get the Lenovo logo, there should be a few F# options. Find the one that says "Enter Setup" or something along those lines. You want to try and access the BIOS and see if your motherboard is still working, or if it needs to be replaced. If that does not work, turn off your computer, and unscrew the cover over the RAM. Take out the RAM and reseat it. If that does not fix your problem, I think your motherboard is fried.

Thanks for using FixYa!

Try to perform power drain on your motherboard.

Procedure:
take out the battery and unplug power adapter
press and hold power button for 30secs
put the battery back in including the power adapter
turn on the unit

there is a jumper on the motherboard for that perpose, should reset on it 3 jumper it is alway on pins 1-2 move it to 2-3 for a few secound and than move it back and reboot system
