Laptop Battery Life Tips

So you forgot your power cord on your way to an important meeting or the coffee shop. We’ve all been there. There’s nothing you can do to stop your battery drain, but you can do a lot to slow its inevitable demise.

If you’ve got a laptop with a really old battery that drains in a few minutes after a full charge, there’s not much you can do to make that old thing last much longer—you’ll probably want to replace the battery before you do anything else. For everybody else, these tips can help you keep your Dell XPS M2010 battery working at peak efficiency.

What Drains Your Battery?

In order to help maximize your battery life, it’s important to first understand what drains the power from your laptop battery, and in a modern laptop it’s pretty simple—the LCD panel is the biggest culprit by far. Microsoft’s Windows 7 Engineering blog has put together a very useful chart that helps show you exactly what percentage each component will drain, which helps us know where to start when trying to maximize the battery life.

The one thing this chart doesn’t point out are add-on devices like flash drives, USB mice, and especially PC Cards—which are known to kill your Dell XPS M1730 battery very quickly. If you’ve got an unpowered hard drive plugged into your laptop through a USB port, it’s going to drain your battery more quickly than if you had a powered one.

Tweak Your Power Plan Settings

The first thing you’ll want to do is make sure that you have a reasonable power plan selected for when you’re rolling on battery power. The high performance plan is always tempting (you’re a high performance user, after all), but you’ll burn through your battery a lot more quickly, so select the Power saver or Balanced plans, and make sure it’s set to turn off the display quickly after inactivity, since that’s the biggest power drain.

Next, you’ll want to dig further into the Advanced Power Plan settings, and make sure that the On battery settings are set to maximize battery life—change the plan to turn off the hard disk quickly, use the low-power mode for your wireless adapter, processor, and especially your graphics card. The System cooling policy setting allows you to specify whether the laptop will rely on fans for cooling, or slow the processor down when the temperature gets out of hand, and can definitely help your battery life, though at the cost of some Dell XPS M170 battery performance.

Adjust the Screen Brightness

Since we’ve already shown that the LCD screen is the biggest drag on your battery life, the quickest way to save your battery life is to use your laptop’s hardware buttons to control the screen brightness—most laptops require holding down the function key and using the brightness keys, and turning it down as far as you can (while still visible) is a good idea. It may seem like an obvious choice, but it’s worth emphasizing at the top of the list for one reason: Of everything you can tweak to improve your battery life, this one change alone is at the top of the list of tweaks that can dramatically improve your battery life.

Make sure that your power plan is set to turn off the display quickly when your laptop is idle, and don’t use any fancy screensavers that overuse the graphics capabilities of your laptop. Many web sites tell you to disable Aero to squeeze more Dell XPS M1530 Battery life, and it’s true that you might get a very small bit of extra life, a couple of minutes at the very most—you will be much better off adjusting the screen brightness and using aggressive screen blanking settings.

Optimize Your Hardware for Power Consumption

Does your laptop have a Bluetooth adapter that you aren’t using? What about IR? Each of these devices consumes power just by being enabled, and if you aren’t using them, you may as well disable them to save a little bit of battery. If you’re using your laptop on the plane, train, or somewhere without a wireless hotspot, use the hardware button to disable the Wi-Fi adapter if you have one, or just disable it manually in Control Panel.

Try to avoid using a PC Card adapter, as they can drain your dell xps m1330 battery quickly, and make sure that your USB devices are set to allow Windows to shut them off to save power—you can find the settings in device manager’s Power Management property pane for the device.

You’ll also want to make sure that your laptop has enough RAM—if Windows has to constantly thrash the disk because you don’t have enough RAM to keep everything in memory, you either should consider upgrading your RAM or running fewer applications at once.

Kill Background Processes and Services

Runaway system processes can do more than just kill your PC’s performance—they can also kill your battery as well. You’ll want to make sure that you close any background applications you don’t need to be running while you are on battery power, and disable any automated updaters, scheduled tasks, and especially search indexing.

Prime targets for removal are things like Windows desktop gadgets, and all of those applications that hide themselves in your system tray. It’s time for a cleanup, so disable or uninstall any application running in your system tray that you don’t actually need. (Only uninstall if you’re still plugged in—no use wasting extra Dell XPS M1210 battery life on that now.) It’s not just good for your battery life, it’s a good practice in general.

If you want an easier way to toggle settings on or off, you can use previously mentioned utility Aerofoil to help you automatically disable Aero Glass, switch between power plans, mute the sound, and even disable the sidebar, all with a tiny, lightweight icon sitting in the system tray.

Use Hibernate Mode When Possible

Using Hibernate mode instead of Sleep allows your laptop to completely power down and use zero power, so if you aren’t going to be using your laptop for another hour or more, put it into Hibernate mode instead of sleep mode, which still uses a trickle of battery life to keep everything in memory.

One of the other benefits of using Hibernate mode that many people don’t consider is that there are any number of ways that your laptop can be accidentally woken out of sleep mode—for instance, a scheduled task for an application that pulls your laptop out of sleep mode to do backups, or just an unruly device that triggers the laptop to wake up. If you are using Hibernate mode, nothing can wake the Dell XPS M1530 AC Adapter laptop other than the power button.

Take Care of Your Battery by Avoiding Heat

Laptop batteries are always going to slowly lose their ability to charge over time, but when a laptop is constantly overheating or used in a very hot environment, your battery is going to die very quickly.

Today’s laptops use Lithium batteries instead of nickel, but there’s a lot of incorrect information out there about how to charge or drain your batteries, so let’s set the record straight: Nickel batteries required being fully drained before a recharge to optimize your battery life, but Lithium batteries are the opposite—you do not need to fully discharge it before recharging, and in fact, if you fully deplete a lithium battery and don’t recharge for a while, it can become incapable of holding a charge Dell XPS M170 AC Adapter.

You’ll also want to make sure that your battery is not always fully charged—Wikipedia points out that if your lithium battery is fully charged all the time, you will lose up to 20% of your capacity every year, no matter what you do. Make sure to discharge the battery sometimes, and if you spend most of your time plugged in at a desk, you would be better off running the battery down to half, and then simply removing the Dell XPS M1210 AC Adapter battery and storing it in a cool place. You can use Hibernate mode to save exactly what you were doing while still shutting down the laptop completely.

I: full of laptop to buy it back OK – NO, the actual charge and discharge times to

Activate the new battery, let your laptop battery longevity, there must be a good start, which was to buy a notebook from the start. New laptop battery at the first boot with a 3% charge should be. At this point, you should not use an external power supply, the battery in the power exhausted, until the shutdown, and then use an external power supply charge, repeated three times, in order to activate the Dell inspiron 1520 Battery. Of course, there are said to be full of 12 hours to say, this is not the battery control circuit for the early Ni-MH battery model is suitable, but for now has a smart charge and discharge control circuit of notebook batteries, it was a joke. When the notebook computer battery is full, the charge current will be automatically cut off. All in all, it is important to activate the battery, battery re-charge point is shining, the three. In order to lay a good foundation for future use.

II: charging time is too long, many charging – Battery life is even more near retirement

Battery charge and avoid exhaustion after the long charging time regardless of your notebook to use nickel-metal hydride or lithium electricity, to power after the exhaustion of a certain charge (charge less than 1%), which is the best way to avoid the memory effect. No memory effect on lithium to say, this is irresponsible and misleading business. Lithium also have memory effect, but its memory effect smaller than nickel-metal hydride Bale. And battery charging in the same way, when you charge the battery to the laptop, try to avoid too long, the general control within 12 hours. As for the prevention of exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with metal objects touch the battery and other precautions mentioned here are limited.

Minimize the number of battery, this is a very effective method. You know, the battery charge and discharge is directly related to life, one charge, the battery took a step forward to retirement, it is recommended you use an external power supply, use an external power supply when the battery removed. Some friends always plug in the power several times a day, and the laptop is equipped with batteries, do more damage to the battery. Because each access to the equivalent of an external power supply to charge the battery once the battery life shortened by a natural. In addition, the best off charging the battery so that conservation can play a role.

III: correction can improve the battery capacity – Error

The so-called correction, is when the battery’s actual capacity and the record control circuit capacity not the same as when the nikon en-el5 battery charge and discharge a depth of operation, the control circuit to record, bringing them closer to the actual situation of the battery, which is a manifestation of the true capacity of the battery operation rather than enhance the capacity of the key factors here is the actual capacity of the battery, if the actual capacity of the battery control circuit in the record than the higher capacity, correction can make the battery appear to increase capacity, and if the battery’s actual capacity than the control circuit the capacity to record low, the correction will reduce the capacity of the battery looks, which is why many people are debating the reasons for correction effect, remember that the true correction is to make the battery capacity is shown by the elimination of between battery and control circuit bias, as demonstrated by the increase or decrease capacity, which is the state of the battery itself, rather than determined by your correction. Because the correction is likely the battery discharge when the depth of the injury, but significantly decreased capacity.

IV: The battery die, then his replacement batteries – the book has a lot of battery self-locking function is often a thankless task.

Many people change the kodak klic-7001 Battery is such a deadly, manufacturers seem to have long been expected to do so, and many brands of laptop batteries are designed with self-locking function, once the batteries out of the control circuit, the circuit to enter the self-locking state, Only the use of specific tools to unlock, before the control circuit will not work, that is the same scrap batteries, laptop batteries batteries are not free to change the batteries, you have to change batteries if not, please remember to look for special battery maintenance company to do the job, their own waste for a small trouble, the kind of effort also failed after the frustration and depression is the most miserable.

V: 99% charge less than 100% since been and continue to charge and it will explode – this is equivalent to my chances of winning the lottery every week

Laptop battery almost no chance of explosion, at most, a result of shell melting heat issue, but few can cause fire, was released a few incidents, the fact is that the production process when the poor in the short-circuit caused by the use of lead, even if it Most species have also been short-circuit protection circuit disconnects the battery circuit Buzhi Yu greater damage, unless it is in the protection of the circuit before the batteries short-circuit (before the time of COMPAQ laptop battery explosion was so caused should be), so things that come in contact with the notebook in my 3 years ago, have only seen two cases. Instead, things like your phone number, or the quality of the battery problem in the final analysis, a large number of low-quality assembly of mobile phone batteries, and notebook computers almost never sell this battery, because no models have a large enough to warrant produce compatible battery.

The reason why, after charging to 99% less than 100%, often because the battery control circuit of the records and the deviation of the state of the battery itself, the battery has not reached the record of the voltage control circuit, so the power control circuit has been charged, in fact, the battery has been filled, the problem can usually be resolved through the correction, but even without calibration has nothing to do, because most of the charging circuit will not be filled in automatically after a long break, and even the wise 99% of auto-refresh the current record is 100 %, even a fool has been non-stop design, but also because the current is very small at this time without causing damage.

The current laptop batteries are basically the temperature detection circuit, when the battery temperature is too high, the control circuit will usually be forced to disconnect the battery to prevent the temperature increased further, so this situation fully to the explosion in notebook computer batteries in place no less chance of winning the lottery jackpot.

No matter how scientific maintenance measures, the battery will always age, if you care to do is put in place to calculate a weekly HP pavilion zd8000 battery, approximately one year later remained 60% to 70% capacity.
