Question My Dell's Battery gone. What are the options?

My Dell's Latitude 6400 laptop's battery has gone and now it only works with connected charger.
What options I have? Can the 9 cell battery be repaired or I should buy new battery?
Or is it the right time to change the laptop?
Please suggest the best option.
Thanks

Batteries are not serviceable, but a new one is a lot cheaper than a new laptop.

Problem is you do not know whether it is the battery or the bit of charging circuit on the motherboard. I had a Dell Inspiron 5040 in the other day showing the same symptoms so I ordered a new battery only to find that it still would not charge. Tried all the "tricks" on YouTube but it still will not charge. Same as yours, it works fine when the charger/power supply is plugged in.

The chances are that it probably is the battery but you can check its wear level with the free version of HWMonitor.

Use the SETUP • ENGLISH button down on the left.

@ pete.i You may want to download this program as well and if the wear level isn't drastic then you will know it is something else.

Well having bought a new battery I already know that it is not the battery. There is part of the internal circuitry that can pack up and cause these symptoms. In some laptops this is a separate small circuit board but in some it is part of the motherboard. Either way as I now only repair computers on a hobby basis I wasn't prepared to look any further having paid for a new battery.

The battery can't be repaired, they deteriorate over the years, the capacity gradually gets less until it's close to nothing.
It will have to be replaced with a new battery.
It's up to you whether you want a new Laptop.

HWMonitor does not show battery wear it only shows what the battery wear was at the last calibration point. The same number appears if you use that in post #6
If you never use the battery or very rarely run the battery down to a very low level, then that number will be not be very accurate.

I would think in most cases where the battery has been used to EOL then they will have been calibrated a number of times.

If the laptop is fine and you are happy with it I would buy one of the replacement batteries that can be had for around 20 in the Amazon link above. If you find that it isn't the battery then losing 20 will hurt less than 50 and you could have a battery near as good as the original. The laptop isn't worth that much.
