Problem with the battery.

Hi and my problem is with the battery not holding a charge. We haven't used the laptop that much and even less with just the battery. I guess I'll have to buy a new battery but my concern is: I read that the problem is in the BIOS and if one doesn't update the BIOS the new battery will suffer the same fate as the original did.Have you heard of this? And how does one update a BIOS?
Thanks in advance for any and all help.

Re: Problem with the battery.

Laptop batteries are notorious for having short life spans if not 'babied' correctly. Similar to car batteries, discharging and recharging can only last for so long, until they, without notice, stop holding a charge. This is for batteries acroos the board, whether Acer, IBM, Black or White, they just don't last very long. They are made as a consumable. The BIOS trick may be true for some, but not for all issues. To update the BIOS, one has to visit their respected Notebook manufacturer's website, usually under 'Support' or 'Downloads' section and check to see whether you have the most current version. If one does not have the most current, download either the floppy version (if floppy disk drive available), or the executable one to your PC. The floppy type will automatically (usually) format and created the BIOS or 'firmware' update disk of your choosing. Full instructions are usually on the support site.

Hi, I have a 1.5kva cyberpower inverter installed but it doesn't charge the batteries even after displaying the input voltage on screen. It will just drain the batteries and then shut down the output.

Unless a battery is completely drained, over time it begins charging less and less. If your laptop seems to run for less and less time each time you unplug it from the wall, you probably need to reset it. This is a simple process.

Disable all power-saving and automatic shutdown programs or routines on your computer. If your laptop power plan dims the screen or goes into sleep mode after a few minutes of idle time, disable that. Unplug the laptop's AC adapter cord. Drain the laptop battery. You can just use the laptop until it shuts itself off, or you can wander away and come back when it's gone dark. Make sure that you do not turn it off or allow itself to shut down to conserve power; you want it to run out of power entirely. If you happen to be in a hurry, feel free to exhaust the computer more quickly by playing a 3D graphics-intensive computer game or watching a bit of online video content. Plug the AC adapter back in and wait for the charging indicator light for your laptop to come back on. Once you see that the laptop has begun charging again you are free to do whatever you like, so long as you do not turn the computer off until the battery is fully charged.

Battery wont work without the charger plugged in

All batteries have a FINITE amount of time before they can no longer hold a charge, if your battery is older then a year it is no longer covered under warranty either. Have you noticed prior to this that the battery was holding less and less of a charge? ALSO batteries do over heat and stop receiving a charge, best way to tell is to keep the laptop plugged in. unplug the battery for a minute, then plug it back in and see on your task bar if it says charging or plugged in not charging. let me know! good luck to you as well!

Battery does not charge is their any easy fix that is not - buy a new battery please?

Hi shaun par914...

If you have an ohm meter, check you ac adapter ouput to make sure it has electricity at the plug and is not defective.
Sorry, Otherwise if it is working, then you must replace your battery as there is no fixing a defective battery.

My Gateway MS2285 didn't charge, so I took out the battery and ran it on AC only and it was okay. Should I do this if i plan on running on AC for a long period? What do you suggest please


The likely cause of the original battery fault and the key to what to look out for in future is a very common mistake in the way laptops are used. A laptop battery, working at optimum efficiency, whether of the older Nickel Cadmium and Nickel Metal Hydride or newer Lithium Ion types, is meant to charge under power and then discharge under use, if it is to have a long and useful life.
This means that it should be used in a similar way to a cellphone's battery - connected to mains electricity and charged up when low or flat and then disconnected from the power and used on battery power alone until the power level means the cycle needs repeating.
Many people, however, unwittingly use their laptops like desktop PCs and leave the mains electricity connected to it even after the battery is fully charged. The common reason that people cite for doing this is 'convenience'.This, however, is a mistake.

Laptops have more flexibility than cellphones in that, if they are mainly used in one place rather than as mobile devices, then it is possible to charge the battery to full capacity, disconnect from the mains, then remove and keep the battery until the next time the laptop's mobility function is required (periodically recharge the stored battery if not in use for long periods of time because the charge slowly dissipates when not in use), reconnect the mains to the battery-less laptop and use it like that, ad infinitum. It is this method of powering the laptop that you have recently discovered.

When a laptop battery is fully charged, what it really wants to do is discharge. However, maintaining the mains connection, prevents it from doing so. The P
ower Management system on the motherboard is designed to cope with long periods of either battery powered or battery-less, direct mains powered use (as you are currently doing), but not long periods of simultaneous battery + mains powered use. A fully charged battery, still connected to mains electricity has no means of discharging and various power sensitive components such as the Power Inverter, Cold Cathode Backlight, LCD Panel and Graphics Chip can become damaged by the power bottleneck created.

Using the battery in this wrong way also gradually depletes the charging capacity of the cells (as seems to have happened to you), until eventually, the cells can carry no charge, meaning a dead battery. A dead battery, where the cells are depleted, left in the laptop with the mains connected, is even worse for the Power
Management System, because the flow of power to the motherboard, via the dead battery cells, is inefficient and intermittent, creating battery overheating, low CPU Cooling Fan speed, inferior cooling and consequentinternal overheating hazards in addition to potential electrical damage to several components (and even burn damage to users' laps).

Loose DC jacks, leading to intermittent power drops and surges, are typically caused by theDC Jack being allowed to take the weight of the heavy transformer box on the laptop's power cable. The solution is to ensure that the laptop is never held, carried or used with the transformer hanging unsupported. This is a very real danger wparticularly when the laptop is moved while being used in a battery-less condition. If the laptop is in use, the transformer should be disconnected, carried, placed on a desk or table near the laptop (if the cord is short) or laid completely full-weight-flat on the floor (if the cord is long enough). If a battery-less laptop is being moved, to be completely safe, it should really be powered down beforehand. Another hazard of battery-less laptop use is the accidental pulling out of the power cable while the laptop is in use, which can cause serious damage to the Hard Drive, CPU, RAM, Cooling Fan Motor, Graphics Chip, LCD Panel, Cold Cathode Backlight and LCD Panel Power Inverter.

Also, always use a Surge Supressor/Surge Protector between the mains power socket and all Co
mputer equipment, never connect the laptop's power cable directly to the mains.

When battery cells are dead, a replacement battery is required for mobile computing and should be bought and installed as soon as possible. In the meantime, the old, dead battery should be removed and disposed of in an ecologically sound manner and the laptop can be used (battery-less) on mains power alone.
Manage any new battery you buy and the AC/DC Adapter in the way described above and you should hopefully avoid problems in future.

Replace your battery to solve this trouble.

Get a battery from a advertiser or anywhere computer batteries are sold.

My battery kept telling me: consider replacing your battery. What does it mean? But she's continous charging and it work even if it unplugged.

I think you have Windows 7 on you laptop. The Operating System continously monitors the charge holding capacity and starts warning well before time. The battery is still capable of holding charge and will give back-up and you dont have to replace it now. However, you may replace it when the back-up time would decrease considerably. Please not that upon every charge and discharge the charge holding capacity of the batteries decreases and ultimitately battery worns out and needs replacement. To enhance the battery life, it is recommended to run the laptop on AC power adaptor (if it is available) and in case of AC inavailability, dont drain the battery completely. Use the laptop on battery on battery only when extremely necessary.

Let me know if any further clarification/ assistance is required.

Good Luck!
Dont forget to appreciate the solution and convey feedback if I could have been of any help!

There is an issue with the laptop charging circuit as the machine indicated plugged in, charging. However, it did not charge at all. Laptop work fine with AC Adaptor.

How old is your battery? Lithium ion based batteries normal life is 2 years starting from the date of manufacture, sometimes even less. Try using another battery and see if it will charged properly. You can also use the adapter in a compatible laptop and check if it will charge the battery.

It will not turn on anymore...when I hit the power button it comes on & then goes back off & will continue until I take out the battery

Hello and thank you for using Fixya's services.

To test the battery, take the battery out of the laptop and turn on with just the adaptor. If it boots, then the battery will need to be replaced. The battery can be found on eBay for under 60 dollars.

If the computer is fairly new, you can see if your warranty covers a replacement. Also, check the manufacturers website to see if there are any recalls for the battery. This is common (recall) for most batteries that go out before their time.

Please let me know if you have any questions and I will be glad to assist.
