Thanks to both for posting. Ground straps are definitely good. I have seen too many blown chips while working in electronics. Personally I use an ankle strap as it is easier to keep it out of the way. Turns out it was not memory but the power supply as suspected. So even though it showed the 19.5+V on my DMM it could not deliver enough current to run the laptop. I rigged up another supply but laptop complains it cannot detect the type, etc. So I need another brick. Would like to use something besides the Dell brick but may have to use one of theirs for the sensing problem. Luckily the ram swap took little time.
Latitude E6520 I would like to reseat/clean/move the ram in this computer to see if it will fix boot problem. I would like some manuals or instructions for locating and accessing it. The Dell page I found is for towers not laptops. Thanks, John
