SOLUTION: Press [F2] to Enter Setup does NOT Appear - Lenovo G470

After spending an inordinate amount of time searching the internet about my problem, and then contacting Lenovo (who told me it was hardware and I needed to return all of the laptops I bought), I managed to magically find the solution to my problem.  Since it wasn't documented elsewhere on the internet, I thought I'd create a post for it here.

 

The problem I was having was that my Lenovo G470 laptop did not display Press F2 to Enter Setup during the boot process, and because of this, no amount of hammering the F2 button would allow access to the BIOS.  I attempted all of the standard fixes, pulled the battery, held power down for 30 seconds, removed the HDD -- nothing would cause this to appear.  Since it was happening on all 3 of the G470s we just purchased, I didn't believe it was hardware.  I reached out to Lenovo Premium Support, and after about 3 minutes of discussion, "Paul" informed me that all three machines were defective and would have to be sent back in for repair, and it would take 4-6 weeks for repair and diagnosis.  

 

As I had been noodling around with the machines for a few days, ONE of the three ended up showing the bios options during the boot process.  At that point, I had been hitting just about every single key on the keyboard during the boot process, so I couldn't identify what it was that I did that caused the options to appear.  A little more troubleshooting and I figured it out:

 

Lenovo G470 machines equipped with the EFI bios do NOT by default show the Press F2 to enter Setup.  The only way to make this appear is to hold the "B" key on the keyboard during power-on.  Once you've done that, the options to enter setup will appear and they will reappear at every boot (matter of fact, I've been unable to find a way to make them go away again, no matter what I hold during bootup).

 

So, if you find yourself with a G470 and you can't enter the bios and F2 doesn't work -- hold the B key during boot.  The options should appear and you should be able to gain entry into the BIOS.

tjefferies,

 

Wow!  Thanks for sharing this - will be sure to share with support.   We really appreciate your discovery and sharing this with the community.   I'm not sure why they quoted 4-6 weeks or repair.  Perhaps 4-6 days, counting shipping, but not weeks.  Will address that as well.

 

Do you happen to have your service case number #? WNxxxxxx ?   If so, could you send to me via PM ?

 

Many thanks!

Thanks for this solution, it worked on a Acer laptop as well, I'm pleased to inform. "Press F2..." message disappeared when I switched to SSD.

Best solution is to do a clean shutdown/reboot without going hibernate/sleep. In this case you can see f2/f12

What will work for you is taking the battery out, put the power cord in and turn it on. Then pull the cable cord out.

F2 will appear then on reboot.

Re: SOLUTION: Press [F2] to Enter Setup does NOT Appear - Lenovo G470

I too could ot enter bios. found out any machine(I have G310) that had windows 8 on it does not shut down when you click shut down goes into deep sleep or something. HOLD the off button until it shuts down. then on boot up it does not work like the legacy f2 to enter the bios you have to actually hold down the Fn key and press the F2 key also together then the bios appears. you can change this in the bios to go back to legacy and only have to press the F2 key but have to make sure the machine is really off by holding down button as it turns back on then shuts off
