I was using the computer a few days ago, full battery, plugged into AC and then all of a sudden it turns off, stops working, fails, dies (you get the point). Pressing the power button yields NO reaction not even a flicker. When plug in the computer the blue "plugged in" light blinks and nothing else works, when unplugged there is nothing.
Again, the laptop stopped working while on full battery, while plugged in and now, whatever i try nothing happens.

My first thought would be that it is a power supply problem. But, before replacing the power supply, unplug the power cord from computer and wall plug, plug it in a gain making sure it goes in all the way.
If still flaky, its probably a power supply problem.
Hope it helps.
Battery is dead or dying. Replace it.
AC adapter is not plugged in. Plug it in.
AC adapter has failed, Replace it.
Computer is overheating. Use compressed air to blow dust build-up out of vents and fans.
I could tell the base unit was about to go a few days ago. Have had the phone for years with intermittent problems but it has been for quite awhile now. However, the screen on the unit started to blink a bit a few days ago. Had a feeling it was about to go but the phone kept working until this morning when it suddenly dies. After reading that changeing the cord might work, I replace the unit power cord with one from my handset and the phone is working again! Thanks for the suggestion!
Was the laptop on when it turned off? It may be a PSU problem but we can determine this by removing the battery. Make sure you disconnect the AC adapter while your removing the battery. Inspect the contacts and make sure`there are no black marks or any other dirt. Leave the battery out and plug in your AC adapter. Try the power again.
There are a couple of possibilities in terms of problems that I can suspect so far. Did anything out of the ordinary happen when the computer just stopped working all of the sudden.
1. Battery has failed and short circuited the contacts
2. Power supply failure
3. Motherboard could have failed in style.
4. Power contacts for the AC adapter are damaged.
Let the battery go all the way dead. You may have to adjust the settings in your bios so that the laptop will stay on until the battery goes completely dead. Then charge the battery. Do this a few times if it does not fix the problem you do need a new battery.
remove the primary battery and plug the computer into an AC outlet using the AC adapter. If the computer starts up, one of the batteries need to be replaced. If the battery light on the of the comoputer is blinking, the battery has reached a low batery level, which may not allow the computer to start up. Plug the computer into an AC outlet using the AC adapter to start the computer and allow the battery to charge.
Ouch! You can't use an AC adapter with any battery-operated equipment you choose to just because the plug fits physically. The A70 requires 5-6 volts, and a Pavilion adapter typically puts out 18 volts. You most probably blew out your Canon's power supply within a few seconds, unless it's fused somehow.
