AAO 8G no signal of life after RAM Upgrade - SOLVED

I just upgrade my AAO 8G RAM by myself. After put ev'ry thing back and plug AC adaptor but the power led won't light and can't turn on by power button.
I also try one solution is take battery and AC off then press power button for 30s and try again but no luck now my AAO like a dead machine

Re: AAO 8G don't have signal of life after RAM Upgrade -SOLVED

Don't know what exactly what's happening with AAO but to day it wakes up after fews day left.

For anybody has the same problem please see below steps that i have done.

1. Last Thursday depart AAO 110 to install new 1G ram after reassemble no signal of life on AA0 (no light even flashing led, can't power on by power button).
2. Try depart few times again to see what's happening but no luck AA0 still dead.
3. Try some method that posted earlier on this forum still no luck.
4. Depart again and destroy the CMOS battery holder (try to detach battery out of holder but done with careless so that the holder is detached out of board)
5. Reassemble again and try to plug in to see but still no luck.
6. Take out battery, power plug and left from Monday to date (Thursday) :geek:
7. Today try whether i have luck or not.
8. Plug DC adaptor into AA0 and power led flashing once, this will be a good signal.
9. Try to press Power button and woala AA0 wakes up.
10. Put battery in and now AAO still fine. :lol:

Very strange behavior of this little AA0.
