Hi thanks for using fixya!!

Is your laptop is brand new? Try to remove the battery. Then, try using your laptop and AC adapter without the battery, you will get the power supply directily from AC adapter. If it works properly, then its okay. Now, try to install back your battery then try to charge it. If not charging, perhaps you need to buy a new battery. However, I suggest you bring your laptop to a service technician to further check the error, before you purchase a new battery.

If you need further assistance, let me know!

Charger seems to have both red and green lites flashing at the same time no sequence and both batteries connected read 4.0 VDC, are these chargers repariable or throw aways


Your manual is here. The section on charging states, that green blinking means your battery is fully charged but blinking red means that your charger is faulty. I would say repairable.

1. Plug the female connector of the AC power cord (supplied) to the AC receptacle on the charger and plug in the male connector on the AC power cord into the wall outlet.

2. The On/Off LED indicator is blinking RED, this is abnormal. Unplug AC power cord from the on-board battery charger and wall outlet. Charger may need to be replaced. Contact an Invacare dealer or qualified technician.

3. When the On/Off LED indicator light is Off, charger is Off.

4. When the Charge LED indicator light is YELLOW, the batteries are charging.

5. When the Charge LED indicator light is solid GREEN, the batteries are fully charged (as their condition will allow).

6. When charging is complete, unplug the male connector of the AC power cord from the wall outlet and then unplug the female connector of the AC power cord from the AC receptacle on the charger.

Nc6000 multibay battery does not recharge


Perhaps remove the multi-bay battery, and let main battery charge all the way. Then reattach multi-bay battery, and see if it's recognized.
(Will charge)

That is AC adapter (Charger) removed, then remove multi-bay battery.
Plug AC adapter back into laptop, THEN plug AC adapter into power.

[You do Not want to unplug an AC adapter from a laptop, with the AC adapter plugged into power. Could be a power surge/voltage spike. Unplug AC adapter from power, when plugging into laptop, or unplugging from laptop ]

Main battery charged, unplug power to AC adapter, unplug AC adapter from laptop. Plug multi-bay battery in, then AC adapter.
(Then plug AC adapter into power)

My laptop not charging


When you say it won't charge, does it charge at all?
1. It indicates that it is charging, but as soon as you unplug the charger the battery quickly or immediately indicates it is dead. If the laptop is off, the LED on the laptop shows it is charging but the battery is always dead,

Or: 2. It is as if you didn't have the charger plugged in. No light on the laptop at all when the charger is plugged in.

Possible solutions:
1. The battery has died and is no longer capable of taking a charge. An alternate explanation if you can't even get the laptop to turn on even though the laptop charge LED is on, is that the internal power supply that converts the incoming and battery voltage to all the voltages required has died.
Or: 2. The power connector inside the laptop is a common failure point. The solder joints break from various minor shocks over time. This is going to become more common with lead-free solder as it is more brittle. Less likely is that the charging circuit inside the laptop has failed.

How do I charge the battery of my ACER note book PC? What is the correct manner to charge it? Should I always plug the Note Book PC into the main AC when I log on to the computer?


Yes you should when the battery is low.
You can check the amount of charge in your battery by -
Open Control Panel - Power Options - click on Power meter tab - un-tick Show power levels on each battery.

Power light for battery charger comes on but goes


from your diagnostic, seems that maybe the ac adapter , thepower supply is the one that is wrong.

if you removed the battery and still having that problem, then you already had taken the battery out of the problem.

get a new power supply, or borrow one to test it.

Dell 2650 DC wont work


make sure the charger you purchased has the correct voltage out and amperage(in millivolts) as requested by the laptop computer, if not you risk the chance of damaging your laptop. although they fit in the power plug, it does not mean theyre compatible. The specs should be located at the bottom of the laptop or inside the battery bay.

My laptop stop charging.


Batteries get old and wear out. Be use AC outlet is working. Check for power light on AC/DC charger box between laptop and AC.

It is common for Laptop charging/power connectors to get worn and/or loose(intermittent). Try to get charging light on PC by wiggling power connection to PC.

If not, if you have a VoltOhmMeter(VOM). check for 5V on barrel power connector on the charger side, that plugs into PC, Outside conductor is GND and Inner connector is (+5V). VOMs are cheap at RadioShack or AutoParts stores and are a handy tool to have around the house. Book shows you how to measure. PC is 120V AC on Wall side of PC Power Supply from Wall Outlet, and 5V DC on PC side of Charger.

Charger may be defective. Cheap on Ebay.

Battery problem...


This issue can be caused by any of the below possibilities. 1.- Computer AC / DC cable is bad not allowing the computer battery to charge.
2.- Battery is bad.
3.- Battery charger board is bad.

Solutions:
1.- Computer AC / DC cable is bad not allowing the computer battery to charge
Verify that the AC and or DC cable is not bad by testing the computer only with the power plug connected and the battery out of the laptop.
2.- Battery is bad
It is possible that if the power plug is good that the computer battery is bad. Leave the computer connected to the power with the battery connected in the computer for at least one hour; if the battery does not charge, consider having the battery and/or the laptop serviced or repaired.
If the computer and/or battery is not in warranty consider just replacing the battery as it is very likely that it is just a bad battery.
3.- Battery charger board is bad
If the battery has been replaced or an alternate battery from an alternate identical laptop does not work in the computer, it is likely that the power or charger board within the laptop is bad. It is recommended that the laptop be serviced or repaired.


This will fix your problem.

My PC won't run with ac /dc power!


Hello. There is a hardware failure with the laptop not the AC charger. AC chargers have some range of protections of their own. If the power requirements of the laptop are bigger then what the charger can handle, the charger will turn off. Also other parameters can bring the charger offline. In your case, you have a problem with a small chip, the battery charge controller unit, witch regulates the amount of current required to propperly charge the battery. When this thing fails, the charging requirements for the battery are reported rong and the AC charger is forced to give more power then necesary. This results in disconnection of the AC charger ( an internal fail safe of the AC charger) and the laptop to swich back to battery power. When the laptop is turned off, it can charge the battery because the power requirements are low, having all processor, main board, hard disk etc turned off. Therefore the AC charger can handle the load. However you will need to have it checked by a service center as it is a hardware fault. Both AC charger and laptop needs that check. The charge controll circuit needs to be replaced probably. It will be a somewhat expensive repair. Don't buy any other battery untill you have the laptop checked. For more aditional info please post back. PS. Sorry for my bad english, I am from Romania, it is pretty hard for me to explain tehnical stuff in english.
