Our recommendation for this issue is trying the BIOS recovery test again.
The latest BIOS version can be downloaded from the following web site:
Please be sure to read and follow all accompanying instructions, which can be found at this link:
Before running the BIOS update, remove the RTC (Real Time Clock) battery and leave it out for 20 minutes. After this period of time, insert the battery back in and turn the system back on; if it displays POST messages, go into BIOS Setup Utility by pressing <F2> during the boot process. Once in the BIOS setup utility, press <F9> to restore BIOS default settings. Reset any customized BIOS settings. Press <F10> to save the new settings and reboot the system.
