Power supply problem

When I connect my dc power adapter to my computer, it does not charge the battery. The charging indication LED blinks twice and goes off and when I switch on the computer with the dc adapter connected, it runs on battery only.When the computer is switched on with the battery removed and adapter connected, it works in adapter supply. Adapter gives a constant output of 19V.

This is going to be with the power management system on the motherboard. These are the classic text book symptoms of a failed power management chip. Few shops will be able to fix this, most just say replace the motherboard, you might get lucky and find one in your area that can fix it, if not then you will need to send it to Acer for repair.

Toshiba Laptop no longer charges battery


When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.

Power indicatoror


From the manual:

"Attach the barrel tip of the AC Charging Adapter to the AC Charging port of the POWER TO GO® and plug the standard two-prong plug into an appropriate, functioning 120 volt AC outlet. The red Battery Status LED indicator will flash, indicating a proper connection has been made and the unit is charging. The green Battery Status LED indicators will gradually light as the charge level rises. The POWER TO GO® must be charged for approximately 11-17 hours prior to first use. All Battery Status LED indicators will be lit solid (the red indicator will stop flashing) when the unit is fully charged.

Discharging Battery


hmmm..try to run it with battery out completely, just from the power cord.

also, does the battery have one of those surface charge indicators, with the sliding scale?

also, plug the unit in overnight, off, and see if the adapter will charge the battery.

sometimes, you get voltage, but no current, and when the computer/battery come on line, the load will drop the adapter.

does the adapter light stay on, when connected to computer?
