I have an Acer Aspire L100 Small form desktop which I was planning to upgrade from 1gb to 2gb memory. To check the memory type before buying I opened the case removed the memory and replaced it however when rebuilt I cannot get the unit to power up. There seems to be power to the unit as the LAN light flashes once (only once) when I plug the power in. I cant seem to find whether there is a case open interlock anywhere that needs resetting or find very much information at all.
Please can someone help and just point out if I am being stupid.
I had a similar problem last year when upgrading my wife's laptop. She had 512MB ram I added anothet 1GB ram module but put them in in the wrong slots so when I tried to power up I got nothing. took them out changed them round and it worked fine. not sure if this is your problem.
Have you tried replacing the old module booting up to see if you get power..if so the new module may be you problem.
