I do not have this laptop, but had a similar problem with my laptop after applying thermal paste and additional RAM. The only indication I got was a blinking orange battery charge LED.

Try:
Remove AC power.
Remove battery connector.
Remove CMOS battery connector.
Press the Power button to completely drain power/current from motherboard.

Reconnect CMOS battery connector.
Reconnect Battery connector.
Reconnect AC power.
Press power button and let it run for a while (20 minutes). Hopefully, it will reconfigure itself and eventually boot. Might be a stuck one or zero somewhere.
