I've had a Gateway MS2274 model laptop for about a year and just recently when I plug in the charger it says, "Plugged in, Not charging." It doesn't make sense to me why it's not charging. - The battery refuses to charge at all passed it's current point - It is continuously decreasing

Any answers?

There is too little info in your question. All I can do is guess.

Perhaps it's not charging because the battery is already fully charged?

Perhaps the battery is defective?

Perhaps there is a problem with the battery connectors?

How long does your laptop operate when using a fully charged battery? Have you been periodically (say once a month at least) been discharging the battery?

it gives the percentage of what is charged and right now it's continually decreasing because it's not working.

Well, it sounds as though the battery may be dying though I'm still just guessing. I tried searching the Gateway site for your laptop but came up empty. Perhaps you would have better luck by visiting Gateway's support page and using the serial number on your laptop.

If you can bring up the Gateway support page for your notebook then look for battery related information. In particular look for something about battery conditioning or maintenance.

Since I couldn't find anything to go on at Gateway's site I fell back to what I am somewhat familiar with, my MacBook. Below is an excerpt of Apple's recommendation for their batteries. I assume your Gateway notebook also uses a lithium-based battery so the advice should also work in your case.

If it was me, then before replacing the battery I would try to completely discharge/recharge it for at least a few cycles to see if that helped.

Standard Maintenance
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month.

it gives the percentage of what is charged and right now its continually decreasing because its not working. it says when its fully charged as well which hasnt been in a while. its plugged in 95% of the time. maybe once a day at most it gets unplugged for a short time then plugged back in. the battery power doesnt seem to last all that long (when unplugged) maybe an hour and a half. – Francesca Jul 21 '10 at 4:49

This can commonly occur with Laptop batteries. If you've had the laptop more than a year, it's feasible that it's worn out from being plugged in all the time.

Batteries last longest if you full de-charge them every so often, then charge it to full again and let it de-charge and so-on.

I've seen laptop batteries go within 9 months with constant use, the most likely solution is a replacement battery.

Unfortunately, batteries are seen as a consumable product, so it's difficult to get a replacement under warranty.

Most likey the battery is defective (if it's very new) or worn if it's getting old.

I would go to a reputable repair shop and try a new charger. If a new charger for your laptop doesn't fix the problem then the chargeing circuit may be damaged, and if that is the case you really want a reputable shop to take care of it.

  1. Close your laptop
  2. Take out the battery at the bottom and put on your charger.
  3. Open your laptop and then open your user.
  4. Close the laptop and take out the charger.
  5. Put the battery back on and then put the charger on
