NiMH technology is used extensively in rechargeable batteries for consumer electronics. Due to their high capacity, long-lasting attribute and easy recharge functions, they are extremely popular among electronic gadgets users.

Li-Ion Battery

This is the most popular and easily identifiable battery type in these gadget-crazy times. One can find these batteries in any or almost every mobile phone being used by people in all parts of the world. A Li-ion battery is a rechargeable battery in which a lithium ion moves between the anode and cathode. During discharge, lithium ion moves from anode to cathode; and from cathode to anode while charging. Due to their high energy efficiency Li-ion batteries are not only being used in electronic devices such as mobile and laptops but also in defense, automotive, and aerospace applications.

First, make sure that the problem is not with the laptop charger. Remove the laptop battery from the laptop. Plug in the laptop charger directly into the battery-less laptop and try to see if you can power up the laptop. If it does not power up, and not even a single indicator light turns on, then the problem is with your laptop charger. If you have a voltmeter, test if there is power being produced by the laptop charger. Also, test if the power cord has no breaks along the line, and that power is not disconnected from the power source up to the output plug.

If the problem is not with the laptop charger, then try considering a software problem. Sometimes the problem can be caused by a software-related issue. And the laptop is not reporting the correct status and power charge of the laptop battery. Try to read up on you laptop’s user manual to determine if the problem is not software-related.

If the battery charges but would not complete itself up to its full capacity of 100%, it might just be a problem of calibration. If this is the case, it is necessary for you to drain the power off your laptop battery completely. And you can only do this by turning your laptop power on until it dies off. It would not happen if you have automatic hibernation mode activated when a certain battery level is reached. O to your laptop’s Control Panel first. Then go to Power Management. From there, adjust the setting on when the laptop automatically hibernates. Usually it is set at around 3%-5% so that laptop users won’t lose the information they are working on if the battery dies up while they are still using it. Adjust that setting to zero. And leave the laptop on until the battery is drained. When the battery dies up, recharge it. See if the procedure has recalibrated your laptop battery, and would allow your laptop to be charged to full capacity at 100%.

Sometimes power resetting the laptop solves the battery problem. You can do this by unplugging it and removing the battery. Then hold on the power button of the laptop for one minute. This would make sure that there is no power remaining within the laptop’s motherboard when the battery went down causing the problem in the laptop battery charging. Return the battery and plug the laptop charger and see if the battery charges now.

If the above solutions still do not work, then the problem may be with you laptop battery itself. It is best to replace your laptop battery with the specific battery that is provided by your laptop manufacturer. Contact your laptop dealer and see if they still have stocks of the said battery. Otherwise, you can also order from online shops offering various types and brands of laptop batteries. Just make sure that you get the right kind of battery which fits the specifications of the original laptop battery.

Technology should help us all move forward without destroying the environment in which we live in. Let us all do our share in protecting our environment. And we can start by doing the simple things like disposing our batteries properly.

Here are a few things that you might want to check up to know if you really need to bring your laptop to the repair center.

Check the AC Adapter

When you plug in you laptop’s AC adapter, you should see the LED light up. It is usually yellow or red when it is charging the laptop’s battery, or green when it is fully charged or running on AC power.

If the LED is not lit up, and the laptop does not show any sign of starting to boot up when you push on the power button, you should check if your AC power adapter is functioning properly.

If you have a voltmeter, test if the AC adapter that you are using for your laptop is producing the right voltage output, or if it is even producing power at all from its output plug. You would know the correct voltage needed for your laptop to function based on your laptop’s manual. If you cannot find the manual, look for it printed in the laptop itself. It can usually be found at the bottom part where the other product specifications are located.

At this point, It may also be worth to try removing the laptop’s battery and unplugging the AC adapter and leaving the laptop powerless for 1-2 minutes. Then try booting up you laptop again.

If the AC adapter is producing power but not in the right voltage, unplug the AC adapter from the power outlet immediately and stop using it. You may damage your laptop if you continue to use that AC adapter with the wrong power output on your laptop. If you have a universal AC adapter, try to see if it can supply the correct power output to your laptop. Usually, it can. And you are in luck if you try plugging in you universal AC adapter with the correct voltage option and the laptop boots up.

Check the Monitor

Assuming that there is no problem with your power adapter, and the laptop powers up when you turn on the laptop, but just would not continue booting up, and there is no image appearing at the laptop’s monitor, you would have to start checking on other things.

If you have a desktop computer, use the desktop’s monitor in checking you laptop’s video output. Your laptop usually has its port for an external monitor located at the back. Connect your external monitor and verify if you can now see your laptop booting up on the screen of the external monitor.

If the external monitor show that your laptop is ok, then the problem is with you laptop’s computer monitor. Bring your laptop to a service center as fixing your laptop’s monitor already requires opening up the insides of your laptop which might void you warranty if you do it yourself.

Check the Memory Chips

Usually, laptops have at least two memory slots. What you should do is remove the memory chips and install it back. (Refer to your laptop’s manual to locate your laptop’s memory slots and how install the memory chips.) If you have two memory chips, try using only one and try installing it in either of the slots. See if it works. If not, try it on the other slot. If it still does not work, try the other memory chip and do the same. You would have to pinpoint the problem by process of elimination. It could be one of the two memory chips. Or it could be one of the two memory slots. Or worse, it can also be a combination of the four factors. See if trying out the different combinations would solve your laptop’s boot up problem.

If the problem is a faulty memory chip, don’t use that memory chip or buy a new one. If the problem is with one of the memory slots, do not use that memory slot or replace you laptop’s motherboard.

Check the Hard Drive

If you can power up your laptop but it just would not continue booting up, and instead, you hear a repetitive clicking sound or grinding noise coming from the inside, the problem may be traced to your laptop’s hard drive.

If you are capable of removing your laptop’s hard drive, let the laptop boot up without the hard drive. Listen if the clicking or grinding noise disappears. If it does, then our hard drive must be damaged. Replace your hard drive with a functioning one.

Or if you can run diagnostic tests on your hard drive using a hard drive test utility and see if the problem can still be solved.

If the above solutions are still not enough to pinpoint the problem of your laptop, then it might already be time to bring it to a laptop repair center.

Also, if you have a DSLR as your camera, you may opt not to use the LCD screen when taking pictures. Since most DSLP users prefer peeking thru the optical viewfinder, it shall save you a lot of battery power if you turn off the electronic viewfinder or LCD display when taking shots.

When you are not going to use your digital camera for a long period of time, it is advisable to remove it from the digital camera and store it safely in a storage that is not exposed to humidity and high temperature. This can also improve your rechargeable camera battery’s life.

And lastly, buy and replace batteries in whole batches. For example, if your digital camera uses 4 AAA batteries to operate, and you sense that battery life is slowly deteriorating that it is already time to replace them with new rechargeable camera batteries, replace all four of them at the same time. Do not make it a habit to replace just two of them, hoping that the two new ones can pull the remaining power from the two old ones. This would just effectively shorten battery life even for the new rechargeable camera batteries that you just bought. And your camera’s usage time would not improve as expected with the new rechargeable camera batteries.

These are just a few tips on how you should take care of your rechargeable camera batteries to maximize the power that you can get from them. Extending your rechargeable camera battery’s life can certainly add up to the cost savings you can get from digital photography.
