How to Extend/Increase Laptop Battery Life - Laptop Battery Tips

-


How can you improve or maximize your laptop battery life? How can you prolong it's life expectancy of lifespan?

These are very common questions for laptop/notebook user. Laptop / Notebook batteries are actually categorized as "consumables". They are expected to wear out in time. So, while you can extend their life expectancy, accept the fact that your laptop battery won't last forever, no matter what even when you're not using it. So, it is not a good idea to buy an extra battery now thinking that you can store it and use it once the original battery has degraded. It's better for laptop batteries to be used, rather than sitting on a shelve. So if you use a laptop, don't plugged it in all the time. Let it drain to about 40% and then recharge.

Laptop battery lifespan or life expectancy

Laptop batteries are Lithium-Ion or Li-ion. Lithium-Ion laptop batteries are rated for a useful life of at least around 400 life cycles. A charge cycle occurs when 100% of battery capacity is used. Properly maintained laptop batteries can retain up to 80% of their original life even after 300 or more cycles.

Laptop Battery Tips

Remove the battery of your laptop/notebook if you're using an AC power for long hours. Why? The heat that your laptop produces can overexcite the chemicals in your laptop battery and therefore, shortening its overall lifespan. Avoid exposing your battery to heat whenever possible. That includes leaving it under the heat/ray of the sun. Make sure your laptop is well ventilated when in use. Fred Langa of Windows Secrets even suggested that if you store your laptop battery, put in a tight plastic bag and put it in your refrigerator at about 4-5 degrees C. Well, I think that is overkill because of the condensation that may occur especially if you are living in a tropical country like me. But the point I like you to see is the idea of how heat can be harmful to batteries.

You will also need to calibrate your laptop battery once a month. Don't worry, it's not as technical as you think. Calibrating your battery is just letting it discharged to zero every once in a while. But don't let it go deep discharge. When your laptop battery drains, windows will automatically hibernate. There's still little charge left on the battery. This reserve will hold the computer’s working memory in state for a little while. A deep discharge has occurred when even that percentage of reserve power is used up. Deep discharges will strain your batteries, so try to charge them frequently.

Taken from: atmaxplorer.com I’ve been receiving tons of questions on how to check if their PSP can have custom firmware installed. Here’s a complete and concise guide to get you going. Make sure to read through the guide fully since it will answer all your psp motherboard related questions. First of, you need to understand that there are three types of PSPs: 1) 1000 Series (Also known as PSP Phat/Fat) 2) 2000 Series (Also known as PSP Slim or Lite & Slim) 3) 3000 Series (Also known as PSP Brite) So why install Custom Firmware on a PSP? People install Custom Firmware so they can run Homebrew, programs developed by people that don’t have a contract with Sony. A PSP with Custom Firmware could also back up your games from the UMD to your computer; it also allows you to play those backups from your Memory Stick (MS). You could also do some serious customizations to your theme. Basically, you free your PSP from the hands of Sony. Why can’t I install Custom Firmware on my ...

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged (code 19)- CD ROM Device Manager Error One of my client brought in a Dell Latitude laptop that has a problem with its CD ROM. According to the owner he can't access his CD. The model of his CD Rom is Samsung CD ROM SN-124. Upon inspection, I found out that the device (CD ROM drive) is missing from his My Computer (as you can see on the image below) At first, I thought that the problem lies with the connection of the CDROM because I had it disassembled a week before due to display problem. The CD Rom is snap in type, so I easily took it out and back in without hassle. Upon logging in to windows, the problem still persist. Next, I checked the Device Manager (right-click My Computer, choose Properties, then Hardware and click on Device Manager). As you can see on the picture below, there is a problem with the CD ROM because there is a yellow exclamation mark befor...
