boot_device_led and slow boot

Specs: w7, x86-64
Got a computer running just fine, but starts doing this:

When starting up, or restarting, after the screen blacks out at the actual machine restart, the BIOS logo (American Megatrends) is shown very briefly, after which the screens stays black, for about half a minute.

Then, the normal boot info (the American Megatrends logo and all of the normal text) appears on it, nothing indicating a problem, and after this, the machine works all OK.

I've noticed that on boot/restart, the BOOT_DEVICE_LED stays on for about the same time that the machine appears to hang with a back screen.

It's really black (!), not just no signal, since the screen itself does not go into standby, which it does when the computer is shut down.

Like to know what is going on, I'm suspecting a failure being announced. I'm going to test my boot-disk

Hi there.

Some kind of USB issue.
When some USB devices (disks in particular) attached, the startup is sometimes slower, but not like half to 1 minute longer than usual (the boot itself can happen in 1 minute actually, without issue).

So you start it up and it shows the motherboard/system logo, goes black and then shows the normal posting screen and things proceed normally? Yeah it could be a USB device. Might also be a bios setting. See if you have a 'quick boot' or similar option in cmos/bios setup.

Making sure the hard drive is first in the boot order may speed things up.

Hopefully the drive LED being on doesn't indicate a drive problem.

I had no issues since then, and I changed only one thing : I removed the USB disk from the boot order. For some unknown reason it was put first. I do use a lot of USB sticks and HD's, but I definately had this config a long time, until he did this.

What changes a lot, is the number of USB disks connected, either it's a problem with 1 specific, or it's the amount of drives connected.

None of those disks was ever confiigured as a boot disk. One or more of my USB memory sticks was, but I had removed them already.

I never had a hang or problem, it just took double the time to startup. Now, all runs OK again.

Hi there.

We're glad you got it figured out. I suppose even though they weren't bootable the bios spent some time checking them.
