Lenovo ThinkPad Edge E545 laptop with Win7 pre-installed.

 

Had it about 5 days, and just tried to boot F8 Safe Mode.

 

It refuses to acknowledge the F8 key and boot into the Safe Mode menu screen.

 

According to Microsoft website, F8 is supposed to work in Win7.

 

Is this a known bug in my hardware?  In Win7?

 

Or, I hope not, is my Windows installation corrupted?

Are you tapping the f8 key repeatedly or just one time . . .

 

If msconfig is working you could just use it to force safe mode on the next reboot.

You can also attempt to use the F5 key at POST  before windows starts

1) Are you tapping the f8 key repeatedly or just one time . . .

 

2) If msconfig is working you could just use it to force safe mode on the next reboot.

 

1) I've tried pressing and holding (which is what the Microsoft website says to do for Win7), and I've tried tapping frantically.  Many many times.  I simply ignores me and boots Windows normally.

 

2) Yes, I can boot normally, run msconfig, and force Safe Mode on next re-boot.  But that kind of defeats the purpose.  The F8 menu is supposed to be there for when you can't start Windows normally.

 

This is a newly purchased machine, and I'm checking it out during the grace period to make sure everything works.  F8 not working is a warning flag to me that something may be amiss.  That's why I'm concerned.

 

 

You can also attempt to use the F5 key at POST  before windows starts

 

At your suggestion I just tried that.  It has no effect.

 

 

Thanks for the suggestions.  I've been researching this on-line for 3 days and am stumped.   Any other ideas?

By the sound of it the key is not working, the unit may need returning, off the top of my head i cant think of a program that uses the f8 key, hence you could check if the key is sending a signal, sorry i cant think of anything else . . .

For the record, I figured it out.

 

I feel foolish, but here's the deal:

 

You have to hold down the red "Fn" key while tapping F8.  Then it works.

 

I don't recall ever having to do this with any other computer.

Glad you found the fix.

 

While following 'Joe C's link it seems lenovo have a few issues in this area.

 

In a related thread they talk about the boot.ini tab of msconfig, sometimes lenovo laptops are released with safe mode disabled.

On my computer (not a Lenovo), I had to fix things in the bios.  Some computer manufacturers have what is called "action keys".  Look at your keyboard, and if the function keys have SMALL letters (e.g. f1, f2, etc), and say a large "picture" on them like a globe, double arrow to the right, etc, there is a chance that that may be the issue.  From the limited view of a picture I saw of the Lenovo ThinkPad Edge E545, I think that this is the issue.

Check these two links out.  I know it's talks about a wireless keyboard and/or slim USB keyboard, but it is a good starting point.

I missed your last post, which confirms what I said about the action keys.  However, look at the links, if you want to get rid of the "fn"+function key, to invoke the standard function keys, and get they function keys back to normal.  Then you would have to use fn+ action key for the action keys.

 

Have a great day!

It's not a bug, but by design (which I hate).

Hello,

Just a "little" thing Lenovo forgot to tell you...

Push the "Function" Key Prior to the F8 key

Then it works!

 

Also, (it sounds like a boot issue)

An easier way to get around this is to take the Battery out (Laptop only)

Then push enter for about 10-15 seconds.

Remove all usb peripherals.

Then put the battery back in and start the computer.

This will reset the CMOS BIOS which can cause issues

 

Hope you fix it

I would not recommend flashing the BIOS as it is risky :smash: and unnecessary if the laptop works.

Just fyi starbucks107, if you had read the entire thread before posting you would realise your answer was in fact given some 12 months ago. Also note i wouldn't have commented at all except Captain_Chicken has misinterpreted your answer to mean 'Flash the BIOS' which is not what starbucks107 was suggesting, removing the battery from your laptop etc does not 'Flash the BIOS' in any way, all it will do is reset the cmos chip to its default settings.
