Re: z40-70 freeze when turning on

Welcome to the forums Felsi!

 

When this occurs in other circumstances it's an indication that something is failing the POST (Power On Self Test). The most likely suspect is the memory...not because it is bad but because the board is not using the correct settings to run it.

You can manually adjust the RAM settings in the BIOS. You may also need to do a BIOS update.

 

Let us know how you get on.

Re: z40-70 freeze when turning on

i am trying to run  9bcn91ww.exe as administrator ,  it start to uncompress the file and at the end get a 7-zip access denied message.

 

i am able to uncompress the file with 7-zip to a foulder. but i´m not sure what must be executed after that (several files) and the documentation also say´s

 

Installing the package
1. Windows
   Run 9bcn91ww.exe (With admin authority)

Check the permissions of the 7za.exe program itself; Right click -> Properties -> Security -> (choose a user)

 

And check that Read & Execute is ticked. On my machine, I had Read access but not Execute.

All you have to do is to update the BIOS bu clicking on the .exe file & re-boot the system.

 

Update us how it goes.
