Tips on How to Extend Your Laptop's Battery Life
Over the years, I've discovered how difficult it is for a lot of PC users to maintain their laptop battery. This issue affected me a couple of times also at least with my first two laptops. I discovered I could hardly maintain a constant battery power and its capacity for a straight 6 months. I'll quickly highlight a few points I'm so sure will prove so helpful and worth it.
1. Avoid running memory and CPU intensive application at the same time. Windows vista and windows 7 user could enable the battery gadget that comes with the OS installation in order to monitor CPU and RAM (memory) usage at a particular instant. Windows XP users may open the task manager and select the the "processes" tab to monitor the CPU and RAM usage. Otherwise, you may download and install another gadget to perform this function like the "All CPU meter". Whenever you notice an excessive usage or when the meter reads too high, it would be advisable to check and close a few running application that are not been used at that moment. Don't give up until the CPU and RAM get relieved and the meter reads a lower value.
2. If possible run memory and CPU intensive application only when the laptop is plugged to AC power e.g. Virus scan should run when the laptop is plugged to AC power.
3. Avoid placing the laptop on soft surface like a rug, mattress or cushion to avoid overheating, in a more general sense, don't allow obstruction of air passage from the heat vent. Locate your laptop heat vent and make sure it is always free to pass air outside the laptop. High temperature and too much heat affects the life span of the battery and drain its power.
4. A lot of people have a misconception and a wrong idea on the charging convention used ranging from people who believe that once the battery is full, the laptop should be disconnected from AC power and allowed to discharge to a level to those who believe on a continuous charging regardless of the percentage charged. Ideally what has worked for me is leaving my laptop plugged even when it gets to 100% once I can keep it at a low temperature. If you experience difficulty keeping a low temperature, then you remove the battery once it is full provided your laptop is on AC power.
5. The most important point to note is not to allow your battery run too low before hibernating or shutting down when there is no AC power at that moment. You should have a percentage or level that you should not get below, no matter what and stick to it. One good thing to do is to edit and set your battery settings from the taskbar to automatically shutdown or hibernate when it gets to the said percentage or level. I would recommend not going below 20% before recharging your PC. There are exceptional cases where you'll need to completely drain your battery and this is when you probably need to re-calibrate your battery for a more accurate reading.
6. You can also download "batterysetupcare". this is a software you can use to monitor the battery's health, the discharge rate, the power and various details about your battery, the time a full discharge would be required and several other vital information.
The laptop battery is one of the most important and precious part. So keeping and maintaining it is gonna go a long way.
