How to Calibrate your Laptop Battery.

A responds to my recent post on how and when should you use your laptop battery. i came across an informative and important guide on how to calibrate your battery when you realise the performance is reduced.

Are you worried why your laptop displays Invalid battery or peradventure your own laptop crosses the battery when adapter is plugged in?

If your answer is yes then i've got good news for you.

After following a few steps you will know

•  IF your battery is still fine. 
• IF you will need another battery.

Before that i will take you through some Do's and Dont's on how to keep your laptop battery to perform at its best.

Do's

• Always Plug-in your adapter when you plan to use your laptop for longer period where there is a source of electricity.
• Use when plugged in.
• Use your laptop in a well ventilated room / environment.

Dont's

•  Do not plug-in your laptop when you are about to go to bed.
• Do not plug-in the adapter to the laptop before you plug it to the main source.
• Always Disassemble the laptop battery from the laptop if you are not going to use it for a long period.

Here is a few steps on how to calibrate your laptop battery. Before you continue, you will need a laptop battery calibrating software which is available on the internet specifically from your laptop manufacturing company's website. Install the application and run a self test after system test.

Step 1

Plug in you laptop Adapter, allow it to be fully charged. 

Step 2

Remove the Laptop Adapter.

Step 3

Reboot the Laptop and go to bios setup page.

Step 4

Run the full self test on the bios setup page, allowing the laptop battery to completely drain-out.

Step 5

Plug-in the Adapter for five minutes then power-on your laptop and allow it to charge up to 50%

Step 6

Run the Battery Calibrating software again to see what you get either still Good or Need for Replacement.

Can Dust Actually Damage My Computer?

The Question

During the last few days, my screen froze a couple of times. After opening the chassis I discovered plenty of dust beneath my mother board. I wonder if that can cause short circuits.

The Answers

1. Dust is a problem from the standpoint of blocking fan vents, or, if deep enough, actually insulating parts, causing overheating, but unless it contains substantial amounts of corrosive or conductive material (in which case you shouldn’t be breathing it), it won’t damage the electrical components (beyond any overheating damage).

What could happen, in some circumstances, is condensation inside the box, mixing with dust and creating a conductive sludge. This would generally only occur if you bring the box in from an extremely cold environment (below 0C, roughly) into a humid indoor environment. The protection from this is to wrap the box tightly in plastic before bringing it indoors, and leave it wrapped for a couple of hours, while it has time to warm up.

2. No way. Unless it over heats. Trust me, I have cleaned server motherboards deployed in Afghanistanor months with inches of dust caked on, still running fine. And as long as you keep them cool, they will survive.
Now, optical drives. That’s a different story.

While you’re at very little risk of a dust blanket shorting out your hardware, heat is the eternal enemy of computers and a good cleaning will help keep things cool (and extend the life of your computer in the process).

How And When Should You Use Your Laptop Battery.

Should you leave your laptop plugged in and charging when you’re not on-the-go? What’s best for the battery? What’s best for your user experience? Read on as we investigate.


The Questions
When your laptop’s battery is 100% charged, should you leave it plugged in so any battery power doesn’t get used, or will that cause overcharging, overheating, etc.? Should the laptop be unplugged when the battery level is 100%?

When I’m at home, is it better to use the laptop plugged into AC power, or with just the battery, for the overall battery life?

So what was the verdict? Should you leave your laptop almost perpetually tethered to the wall or only charge it when the battery charge is running low?

The Answers
The answers to the questions isn’t a cut and dry “Yes, leave it tethered” or “No, unplug it”  because of the variety of laptop designs, their battery types, and the integrated charging circuit that recharges the battery.


It won’t make all that much difference. What will shorten battery life is temperature: If it gets hot, it will shorten the battery life. Best thing to do, if you are able, is to remove the battery while you’re at home and keep it somewhere cool.

If it’s a Li-ion battery, then they don’t like to be completely discharged, so make sure you charge them regularly.

Wikipedia on Li-ion batteries

Lithium-ion batteries should not be frequently discharged fully and recharged (“deep-cycled”), but this may be necessary after about every 30th recharge to recalibrate any electronic charge monitor (e.g. a battery meter). This allows the monitoring electronics to more accurately estimate battery charge. This has nothing to do with the memory effect.


Question
What about the “Remove the battery!” camp? It turns out that while removing the battery can be beneficial, the situations in which it is beneficial are fairly limited.


Answer
Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop.


However there’s a disadvantage in keeping the battery in its socket when the laptop is plugged in, but only if it’s currently suffering from excessive heating caused by the laptop hardware.

So:
In a normal usage, if the laptop doesn't get to hot (CPU and Hard Disk around 40ºC) the battery should remain in the laptop socket;
In an intensive usage which leads to a large amount of heat produced (i.e. Games) the battery should be removed from the socket in order to prevent unwanted heating.
The heat, among the fact that it has 100% of charge, is the great enemy of the lithium battery and not the plug, as many might think so.


The best plan of attack then, is to monitor your hardware to ensure you’re not overheating your battery and be concious of the limitations of the type of battery in your device–for the majority of users, a Lithium-Ion battery.
