You can try switching off computer, unplug the ac adapter, then the battery. When all power source are removed, hold the power button. Then put the battery back on then try switching the laptop back on.
Try to unplug the ac adapter (charger), remove the battery(located on the bottom) and without the power sources (w/o battery and ac adapter), hold down na power button 10 secs. Put the power sources back and turn ON the laptop.
Is the ac adapter, battery and power indicator light illuminated?if it is.
Try to unplug the ac adapter (charger), remove the battery(located on the bottom) and without the power sources (w/o battery and ac adapter), hold down na power button 10 secs. Put the power sources back and turn ON the laptop.
First, disconnect the laptop from the ac adapter and take off the battery and the memory. Press the reset button on your laptop. Connect your ac adapter only and press the power button two or three time while everything else is disconnected. Then, re-install your memory and your battery. Connect the ac adapter to the laptop and to your power source. Now turn on your laptop and see if you get a display on your laptop screen. If you do, then you have reset everything and you are back to where you started. Good luck and let me know how it goes.
Most likely your power I/O board *(cant remember the real name) that connects to your motherboard (where you plug your ac adapter into) has gone bad or has a loose connection.
If you have the AC adapter plugged into the portable, it will run on AC power while recharging the battery. Once you remove the AC adapter, it will go onto battery power.
If once you remove the AC adapter the computer dies, with a battery installed, then your battery is weak/dead or there is a connection problem, and the battery is not charging. But, I doubt this is the case, since it thinks the battery is at 80%. The system does not know if the battery is holding a charge.
You power settings are only timers, which reduce power consumption when idle.
Its not the battery, its AC power source providing your problem.
Check if AC connector goes in as far as it should on your laptop, check so you dont have a weak link on the cables on the AC. My guess is that the power sorce or the cables on is defect someway.
