sounds like a memory error
if you have 2 modules remove one to see what happens
1 may be under the keyboard if you have 2
I tried the memory modules one at a time, still getting errors. I took the system apart trying to narrow down the problem.
I go to the BIOS RTC battery and pulled it to check the voltage, I read 2.87 VDC battery is rated for 3.0. Thats OK I guess
No I am getting a beep code of 4 beeps followed by nothing but CPU fan running. Any ideas? Oh, the manual says this 4 beep codes means "System Board error-Security Chip".
