NUC7I5BNK no post

[NB8]

I updated bios on this machine to 0085. I regret it because it was a perfectly running machine before the update. 

After the update I was able to get visual bios menu and did a few restarts. After that I either enabled legacy usb or disabled it (can't remember) and after that no post. LED solid blue.

Here are a few things I did:

- checked hdmi cable and monitor working on another computer

- power menu to recover using FAT32 formatted on windows machine usb with only file BN0085.bio

- recovery using jumper

- removed cmos battery for a day and attempted recovery

- I contacted support and they asked me to remove memory and ssd and then power up. LED was flashing blue. Power down and install only one memory module and try recovery. Still no post. Unit out of warranty and can't help me further even though this isn't really a hardware failure but a bios update that caused this. 

Is there anything else I could do?

Hi @NB8 ,

1. Disconnect al devices connected to the USB ports. Leave only keyboard and mouse.

2. Enter BIOS from the Power Button Menu (click on F2)

3. Reset BIOS to default settings: while in BIOS, click on F9 confirmed by "Y" and then F10 ("Y").

Sorry for not being clear. What I meant by ‘no post’ is that there is no screen activity whatsoever. In fact monitor goes to sleep if left long enough.

Only keyboard is connected.

Thanks.

Can you boot into Power Button Menu? :
Press and hold Power Button for about 3 seconds. Count 1001, 1002, 1003,1004. Release the Power Button. NUC should reboot into Power Button Menu. You should release the Power Button before 4-sec shut down override or when the Power Button LED changes color from blue to amber.

Unfortunately not, neither does removing jumper make it go into recovery mode when usb flash plugged into yellow port.

In this case we may try to reset BIOS, using "blind" method:

1. Remove the power cord and remove the yellow security jumper. Leave only the keyboard/mouse (without any USB stick in the USB port).

2. Reconnect the power adapter and power ON the NUC (without security jumper) . Wait about 2 minutes.

3. Click on F2 and wait about 1 minute.

4. Click on F9 and then on "Y" key. Wait about 10 seconds.

5. Click on F10 and then  on "Y". Wait about 30 seconds.

6. Press and hold the Power Button until NUC is OFF. Remove the power adapter and replace the security jumper between pins 1-2.

7. Reinstall the bottom cover, reconnect the power adapter and check if the NUC.

I went through the procedure multiple times and still not getting anything on the screen. Thanks for trying to help with this.
