My M465-E was left in standby mode overnight (AC adaptor plugged in). When I attempted to restart in the morning nothing happened; it will not turn on. Battery shows fully charged and using AC adaptor does not make a difference. I have held the on/off button for extended periods of time with no change. Any suggestions? Thanks much.

Please turn off the Computer and disconnect the AC Adaptor then remove the Battery. Next, try cleaning the metal contacts on the Battery and reseating the RAM modules.Then, connect only AC Adaptor to the Computer and try to turn it ON without the Battery. If the Computer doesn't turn ON then disconnect the AC Adaptor and insert the Battery then try turning ON the Computer. If the issue persists even after performing all the above steps then service will be required.
First of all, what I'm about to tell you are general troubleshooting techniques - I make no claim that they will fix what you describe, but they may help lead you to a solution.
Unplug the AC adapter and remove the battery
Plug in the AC adapter and attempt to power on the laptop
If it doesn't power on, see #6 below. If it does power on, but doesn't boot the OS, restart - pressing [SPACE] as the first Windows splash screen appears. When prompted, choose to delete the hibernation file and start a system boot.
Shut the system down, disconnect the AC adapter, reinsert the battery, and attempt to power the laptop. If it doesn't start we know, at the very least, there's a battery problem.
Plug in the AC adapter. If it shuts down immediately, or won't power back on after a shutdown. . .
. . .there's a problem with the system board, probably the ciruitry associated with charging the battery.
Sounds like the motherboard may have gone bad on you.
If your ac adaptor has a light on it, make sure it still has the light still illuminates when you plug it into a wall outlet. If it doesn't light up then it could be the adaptor but since you tried both just the battery and just the ac adaptor that would tell me the motherboard is bad.
The only other option would be to resolder the dc jack on the motherboard back in place. It could be that the solder joints underneath the dc jack have cracks in them.

3. Examine the power cord to ensure a good connection between
the rear-panel AC input connector and the wall outlet.
4. Check the electrical circuit and breaker.
Try this; Disconnect from the AC outlet rmove the dc plug from the jack. Remove the Battery and wait for 5 mins and plug in the AC-DC adaptor without the battery. If the Laptop runs, then wait for the Windows to totally boot up and while running try to put back the battery and observe if it still charges. If it still won't boot up repeat the procedure and before connecting the power remove the memory modules first and install 1 memory at a time. Also, if you can find your way to where the CMOS Battery is, I suggest disconnect it for about 10 to 15 mins. while Battery, memory, AC source are also disconnected.
