I bought a Dell Precision M6400 (#2) recently on Ebay and it arrived earlier today. Cosmetically the unit looks new, like it's seldom been used. I need some advice because it just won't Boot To the Bios screen. The unit came without a HDD. 

 

When I power on it will not Boot To Bios and I tried for about an hour. The Dell logo splash screen appears on Power Up normally and the Bios progress bar makes it to 98% and the screen goes black and keeps trying to fully load. Fast at first and then gets very slow the last 80%. Makes it to 98% and keeps re-trying.  Below the progress bar on the splash screen read Bios Version A13, which is the latest version.

 

The seller did tell me that it may be 2GB of RAM and not 4GB, that a stick may have been removed. I get nothing when I try F2 and when I try F12 I get a little message top right in yellow, "Preparing For One Time Boot Option" but that disappears when the progress bar reaches 98% and tries again and again. 

 

I think it's something simple. When I get time tomorrow I'm going to start checking the RAM and see if it's seated properly. If that isn't the culprit what should I check next?

 

Dell Precision M6400 P8600 2.40 Ghz

 

2 or 4 GB DDR3 PC3-8500 DDR3 

 

Nvida G94 Graphics Dedicated

 

WUXGA

 

No HDD

Hi jackz4000,

 

I’d I'd suggest that you follow the steps mentioned below and check if your able boot into the BIOS.

 

1. Switch off the computer.

2. Disconnect the AC adapter from the system.

3. Remove the battery from the computer.

4. Press and hold down the power button for 15 seconds.

5.  Then connect back all the peripherals and check if you are able to boot into the BIOS screen.

Thank you Ravi-Dell I tried that and a couple other Power Button variations. No change. Progress bar fills to 98% and then restarts and fills to 98% and restarts and...

Later today I'll check for loose connections and make sure the memory is seated correctly and disconnect the CMOS battery for 2 minutes.

The OS is looking for a hard drive.  Connecting ANY drive should get you into the BIOS.
