CCFL replacement (1 of 10)
Image by Tim Musson
My cousin Ken’s computer is a second hand HP/Compaq nx9040. The screen’s fluorescent back-light died, and getting it fixed was going to cost more than the computer was worth – over NZD0, according to one quote! (The back-light is what lights up the display. Without that, the laptop is pretty much useless.)
So I decided to try fixing it myself, with a NZD lamp ordered from www.lcdparts.net/. I was also helped by HP’s service manual for the nx9040, which shows which screws and clips let you open the case and get at various innards.
I took photos to help me put the thing back together again if I got lost.
Of course, I removed the computer’s battery pack before starting. I also removed the hard drive (taking care not to touch any electronic components) in case of accidental bumps and knocks.
About This Macintosh

I’ve been playing with this old PowerBook 150 laptop. Equipped with a 33MHz 68030 processor, 120MB HD, passive-matrix 4-bit grayscale screen, and 4MB of memory. It’s running System 7.5. Not bad for 1994. It’s in nice condition aside from a broken hinge on the right side of the lid. Unfortunately the 14 year old battery seems to have given up the ghost, so I have to run it on AC power.

Notebook battery life is not determined by the length of time, but by the number of charge and discharge decisions. This is the importance of maintenance of notebook battery – Li-ion notebook battery (Dell latitude d600 battery) life by the number of charge-discharge decision! If you are using a laptop when the battery has been installed on the notebook instead of taking down, even if the machine shut down and removed AC power, the battery would not like to imagine that as you have maintained a state of full power.
Used because the notebook battery is a Into a control circuit, even when the computer is shut down power consumption. After I connected to AC power, when battery power is not full, so it will start charging. In this way, when the power turned on or off, your laptop battery will repeatedly charge and discharge and shorten Dell d620 battery life, this is the laptop battery maintenance bogey.

Laptop Battery Basics and Usage Tips
Laptop battery is very much essential for the usage of laptop, because without battery it is not possible to use it on the move, as it requires a power outlet. So as a main accessory for the usage of the laptop, the battery must be in a good condition and work properly. Some of the general tips for laptop care are to avoid extreme temperatures, and not to leave the laptop outside in cold weather or in high heat, as cold batteries cannot generate much power and hot batteries will discharge very soon. Charge the battery whenever it is necessary and when the electrical power is available. The battery charge is indicated in the taskbar of the laptop, which shows the current battery capacity and remaining time. When a laptop is used as a replacement of desktop the battery should not be left in for long time. Battery must be re installed every three to four weeks and allowed to fully discharge.
Smaller the battery better are its functionalities. For instance take into consideration an ultra portable or thin and light battery rather than a bigger one.
Power control settings must be adjusted accordingly as the laptop will go inactive after a specified time which is beneficial for the battery.
Adjust the screen brightness to lower setting according to the working conditions or the place of work which will save the power.
Battery consumption must be noticed often, so that the battery power will be in control. In this case the battery charge indicator must be on the task bar .
Charge the battery whenever necessary and when the power source is available. Especially you are on travel; charge the battery fully as electrical outlets may not be available at the destination.
Clean the batteries and their connections often. It must be done by using a cotton swab and alcohol. Don’t keep the laptop idle for long period of time without using the battery. Using the laptop to play games or to watch movies or multimedia activities will drain the battery soon. Laptop speaker volume must be kept in mute or decreased to low level. Don’t run any program directly from a CD or DVD, instead it can be copied to the hard drive and can be used, which will consume less power.
Before the first use, a new battery must be charged fully. Then the battery has to be charged twice or thrice for achieving maximum capacity. If the battery is not used for more than a month, it is better to be removed from the laptop and stored in a cool or dry or clean place. Again the stored battery has to be recharged before use till it reaches its maximum capacity. Laptop batteries last for longer period if they are stored in a cool place and maintained properly.

Incase Hardshell Case
Image by hawaii
The Incase Hardshell Case for 15" MacBook Pro. I chose the Incase over Speck because I liked the rubberized, matte surface, and the build quality seemed sturdier (but that’s purely conjecture). It snapped on easily, and a nice touch was the battery power meter button passthrough. The "clips" that secure the Incase to the laptop are more subtle than on the Speck, but I’m not a fan of how Incase embosses its own logo on the lid (whereas the Speck advertises only on the bottom piece).
My main complaint about the Incase was the right rear lower corner would catch on the MBP screen edge when I opened it up, making a teeth-gnashing snapping sound. I ended up filing down the edge a tiny bit, and now it opens without catching or rubbing. For something that costs so much and brags about how finely its engineered, though, this seems like a big flaw.

In addition the NiCad batteries wasn’t eco-friendly and their dumping causes harm the surroundings also. These Ni-MH batteries confirmed a improved Power to Weight ratio than NiCad batteries, yet again it showed the dilemma of Memory Losses and so most of the manufacturers again shifted themselves from Ni-MH to Li-Ion which we still utilize today. These Li-Ion batteries showed the improved Battery backup features and longer lifetime as well. Owing to this majority of the Laptop manufacturing companies like HP, Dell, Sony Toshiba etc shifted themselves from Ni-MH to Li-Ion Batteries. These Li-Ion batteries have a smooth charging feature and as well discharges very gradually, as a result giving improved Power Backup, additionally its Power to Weight ratio is extremely less which makes the Laptop as a whole much lighter than earlier Laptops. The next thing on which the duration of the battery and as well their Standby time depends on the handling practice of the client.
