Targus ac70u adapter; 0% available, ( plugged in, not charging )

Hi, well i'm having this problem with my Targus ac70u adapter to charge my laptop, and when i hover the mouse over the battery in the corner to see how much percent my laptop is charged[i have windows Vista] it says; " 0% remaining, plugged in not charging. " When I unplug the charger, my computer immediatly shuts off, and i have to plug it in, in order for my computer to turn on. I have a Compaq C500 Presario, and Windows Vista. This charger has worked before.. so i don't see what happened. Please don't tell me to unplug it because i have done that enough already..
Thank you ^.^

How old is your laptop? It may just be that you need a new battery if it won't hold a charge.

Further, this charger worked previously on this laptop and with this battery? If so, you definitely might be ready for a new battery.

Is the Tagus adapter your original adapter?
Check the adapter wih a multimeter to see if the voltage output is or slightly greater than what is printed on the label.
The adapter may not have sufficient amps to charge the battery and run the laptop, check the current rating of the original adapter and compare it with the Targus, it should be the same voltage and current rating or higher current rating.
If the adapter is OK then the battery is worn out and needs to be replaced. Recharageable batteries have only a limited number of charge and discharge cycles, when this is reached they just don't work any more. Buy a new battery, not a 2nd hand one because of the reasons I've mentioned.

It would that you have a low powered AC adapter. The wattage output of the adapter will cause the problem you are having. Try shutting the laptop down, not suspend, and letting it charge over night. This should charge the battery. I have found that an underpowered adapter will not power both the laptop and charge the battery. You may want to check in the battery compartment for the adapter part number and see if you are using the correct one for your laptop. Please let me know how it goes.

Hi there. Your problem seems to be the battery. Usually when the battery is at the end of its life the indicator stays at 0%. If you are still unsure you can go to download.com and get free battery testing software. Good luck...

It is either the adapter or the connections to the motherboard. It would definitely feel better about telling you which one it is if you could try another adapter. Last thing i can say for now at least is have your ac adapter checked and make sure it is putting out the required power.

No power


Try purchasing an original adapter. I've had several machine of different make through my shop that the Targus adapter just simply won't run. For example, a Dell Inspiron 1100 and HP dv4000 won't run at all, and a Dell Latitude 1501 and Gateway crv503 will run but won't charge the battery. Targus adapters are junk, if you can, get your money back.

Notebook smells like burning plastic.


cud be your onboard voltage regulator for the battery charging. if you remove the battery and use the external power source does it smell also?
if the battery charges normal out of the unit, and the laptop works well with the AC power unit without the battery, then it's your voltage regulator for the batt charging

Targus 70watt adapter


Mine was brand new and it worked for 2 days then started doing that. I know it's not my laptop. I work in a computer shop and I tested it several different ways. I think it may be a faulty capacitor. either way, you just have to replace it. That's what I am doing. I would suggest the same.

Notebook smells like burning plastic.


If the new Targus charger is really rated correctly for your laptop, your battery isn?t charging and you smell the burning plastic coming from the laptop when you plug it in that is a fairly dangerous situation and you shouldn?t plug it back in anymore. The power from the charger runs through a PCB board which distributes power to other components in your laptop. I suspect one of the components (probably a capacitor) had a catastrophic failure and is the cause of the smell and the lack of battery charging. Once again assuming that the Targus is the correct one for your laptop current you probably have a laptop damaged beyond home or economical repair.
