Dell Optiplex SX260 Computer Won't Boot Up
Hi,
Here is an update: Using a "lo-pwr ohms" (low voltage) B&K meter, I measured about 5.5 ohms across the bank of 2200/6.3 caps numbers C146, C147, C148, etc. Note: This reading is not caused by charging. I switched to "hi-pwr ohms" and the reading dropped to 4.4 ohms. Note: 412mV measured (via a DMM) across B&K meter probes during "hi-pwr" ohms reading. It is possible that one or more of these caps is the cause of this low ohms reading (not normal). There are about 9 or 10 caps in parallel. I will put this on the side for now, and wait for more "freedback". Thanks in advance, John |
