No power getting to systerm

check the throttle control switch on the top of the paddle. i'm presuming it is the model without the accelerator cable. electronic control systerm.

Hi Tim, As per my understanding you are experiencing issues with the laptop not working without a charger being plugged in.In this regards what I would suggest you do is see if the battery charges with the charger plugged in and in case the battery does get charged see if you are able to power on the laptop with just the battery connected and no charger plugged in.If you are able to get the laptop to turn on only with the charger connected and unable to power on with just the battery then it would be an issue with the battery not getting charge.So before you replace the battery please unplug all external devices from the laptop including the charger and the battery and without the charger or battery connected to the laptop please press and hold down the power button for 30 seconds after which please insert the battery into the laptop and see if you are able to turn on the laptop.This step is performed so that we could drain out unwanted static electric charges from the laptop.In case this step does not work please do consider replacing the battery since it would be an issue with the battery not getting charged. Best wishes for your effort.

try taking out the ram and putting it back in then if that doesnt work then try shutting down the comp , taking out the battery taking out the power supply and then pressing and holding the power button for 20 seconds , by doing both of these it resets on the info on the ram , or resets the bios to defalt settings

It sounds more like the large portability battery has been 'messed' i recommend getting a new power cord. Whist you may have repaired the cabling and it may have appeared to work, the escape circuit for charge may have been broken but it is not required for the laptop to work, but is important when recharging the battery. I recommend getting a new adapter and then if that doesn't work a new large battery also.

Hi,

have you already tried to power up your laptop without the battery, only with the powersupply docked in?
If this works, you´ll have to replace the battery or use the laptop without a battery.
If this doesn´t work, just take the full battery from the other laptop try to power up the laptop without the power supply docked in.
If this works, your latop motherboard is broken and till it is replaced, you have only the chance to work with a battery and reload it with another latop.

Yes your laptop should power on with just AC power. The issue could be a loose connection for the AC power which caused the battery to stop being able to charge also. Unfortunately only solution for that if it is incase the problem is to open the laptop and have the power connector re soldered onto the board.

you have to restart your n72 . by entering *#7370# an pressing ok your systerm will ask your security code the defalt code is 12345 and your systerm will format . if this not works then go any hardware shop near your house

here you may get your answer.

The blinking orange battery light generally indicates that the battery isn't working properly, usually going out and not charging properly. In this case, since the adapter will not power the machine without the battery, and it should, I'm going to say that the adapter is going out and not getting the proper amount of power to the system. Try replacing the adapter. Be sure to replace it with a Dell replacement, the Targus brand universal adapters do not work well with Dell machines, and in most cases won't work at all.

the battery is empty
