Windows 10: Laptop not booting up (no fan as well)

Hello,
a sony vaio laptop from 2011 just stopped working.
It was on sleep mode and I tried to open it but nothing happened.
The fan, the monitor and the hdd are not turning on.
The cpu is working as it gets hot.
The cdrom is also opening if pressed.
I tried to connect to an external monitor but nothing.
I get no sound verification.
I Changed the ram to working ones with no result.

Any ideas?
Thanks!

:)

 

Cooling external Fan

Hi Paul,

For us to isolate the issue with your external fan, please provide the following information:

• When did the issue start?
  
• Have you tried connecting other USB external devices to your laptop? If yes, what was the result?
  
• Have you tried connecting your external fan to another computer?
  

We're looking forward to your reply.

 

Install Windows 7 dual boot on Windows 10 laptop with GPT partition

Hi Krishna,

Really appreciate your advice! But, unfortunately, neither of your suggestions re shutdown worked for me.

In answer to your questions:

• What is the make and model of the computer? - Lenovo B570
• What are the troubleshooting steps that you have already performed? - all that I can find on the internet, eg stopping quick resume, powercfg, etc etc etc
• What exactly happens when you try to shut down the laptop? - the power button light stays on, and the fan speed increases
• How exactly are you trying to install Windows 7? - keep Windows 10, reinstall Windows 7 in a new partition for dual boot.

Note: I only have 1 hard disk in my laptop.

Thank you and any other expert will is willing to help out!
