After having searched the web for advise about fixing a sticky keyboard on my laptop, and finding nothing very
helpful, I put together this HOWTO based on my own successful method. This will restore the keyboard to new, or
better, performance.Laptop keyboards don't wear out, they foul out. Proper cleaning and lubrication as
described here will restore your laptop keyboard to the snappy and smooth performance it had when new. There
are several reasons why the keys will start to stick, spilled drinks, normal wearing off of the factory
lubrication, weakening of the rubber pieces which give each key its snap action, and contamination by dust and
hair. The following will completely solve these problems and return the keyboard to perfect operation.
This will require about 2 hours time once you have collected the proper cleaning materials.
Cleaning materials:
Cotton swabs
Cosmetic foam rubber cleaning pads ( use only with naptha (lighter fluid), NOT alcohol)
Paper towels
Rubbing alcohol
Water
Lighter fluid (naptha)
Fine tipped tweezers
Scissors
Kitchen strainer
Household cleaner, Windex or equivalent
Super Lube Dry Film spray (critical - DO NOT SUBSTUTUTE !) K-Mart automotive.
This is a PTFE (teflon) based lubricant which dries perfectly DRY and is ideally suited for this application.
Proceed as follows:
DISASSEMBLE
IMPORTANT: Make a keyboard map so you know where each key goes.
Carefully pry each key loose with a small screwdriver and place in a container. They pop off. DO NOT use
excessive force. There may be a small rubber piece for each key. Remove all of these and place in a separate
container. CAREFUL, these are small and like to jump away.
CLEAN KEYBOARD ( do this well...... you will be wonderfully rewarded )
Clean the keyboard with cotton swabs SLIGHTLY DAMPENED with water. Replace these often and BE SURE they are
only slightly damp. If they are too wet the excess water will contaminate the keyboard through capillary
action. This will clean all water soluble contaminants like Coca-Cola, coffee, and sugar residue. For the very
small places, cut the foam rubber into small pieces and use the tweezers, again SLIGHTLY DAMPENED, for
cleaning. You must clean each and every key space, inside and out, this is critical since this is where the key
touches and moves.
Repeat this procedure again using rubbing alcohol and cotton swabs but NOT the foam rubber as it disintegrates
when used with alcohol.
Finally repeat this procedure using naptha (lighter fluid) and foam rubber. You can clean even the smallest key
guides with small pieces of foam rubber and tweezers. This action will remove any petroleum based contaminants
as well as the grease that is sometimes used on the wider keys which may have guide wires, for example, the
SCACE BAR.
CLEAN KEYS
Some keys may have wires attached and some grease on them, clean these first with cotton swabs and naptha
(lighter fluid). Remove all traces of the grease.
Place all keys in a kitchen strainer. Spray with household cleaner and let stand for 5 minutes. Rinse
thoroughly with hot water and place keys on paper towels to dry. Let dry completely.
CLEAN RUBBER COMPONENTS
Place all rubber components in a kitchen strainer. Spray with household cleaner and let stand for 5 minutes.
Use stopper in the sink so that you don't lose these if they jump out of the strainer. Rinse these thoroughly
with hot water and place on paper towels. Fold the towels over and press to squeeze most of the water out of
the pieces. Let dry completely.
LUBRICATE KEYS
Place all keys bottom-up on a paper bag. Lightly coat the keys, at a 45 degree angle with Super Lube Dry Film
lubricant. Do this from all 4 sides to assure penetration and coverage into the small and critical guide spaces
inside each key. Let dry ( this happens nearly instantly). DO NOT overdue this step as the carrier solvent may
affect the plastic.
LUBRICATE KEYBOARD
Mask off the laptop with paper and scotch tape. Apply lubricant (as above in LUBRICATE KEYS) to the keyboard
and let dry.
All right, you now have perfectly cleaned and lubricated keys, keyboard, and rubber components.
REASSEMBLE
Place all rubber components into the keyboard.
Install keys with wires. Make sure wire is secured in the key, usually snapped into place. Place ends of wire
in the guide slots adjacent to the key location as you align the key. Firmly press down to snap the key into
place.
Install the rest of the keys by aligning and firmly pressing down.
CONTRATULATIONS, you now have a keyboard which will operate smoothly and perfectly for years to come.

There is a lot of money being spent trying to turn internet video into something its not. Its not TV. It's certainly not going to be HDTV. What is shocking about the entire
attempt to turn the internet into a tv/HDTV distribution medium is how much people lie to themselves about what is actually happening.
First of all, 100pct of the internet video that you see offered on the net as HD, is not HD. Plain and simple. What is HD video ? HD Vidoe is video you can watch on a screen of
ANY size and say..."that looks good, almost as good as it can get ". What is currently being passed as HD, is video that looks pretty good because its being played on a small PC
or Laptop screen and for the big timers, even a 17" screen. Well guess what, everything and anything coded at 2mbs and above is going to look good on a small screen. But looking
good on a small screen doesn't cut it. In fact, video that looks its best on a 27" TV is not going to cut it. For those of you who don't see it that way, do some research on fhe
history of Fox's Wide Screen broadcasts and see how owners of HDTVs 40" in above felt about those broadcasts compared to what they got from other networks. In a nutshell,
WideScreen is gone. The quality wasn't good enough.
I'm not going to go on my 19th nervous tangent about why video over the net has problems and HD over the net is not going to happen. Instead, I will give the quick and dirty on
what should happen.
There are already multiple digital distribution systems in place that distribute video, in SD and HD to our homes in place. Not only can they get the signal to our home with
99pct uptime and zero buffering but there are any number of systems in place that allow the signals to be distributed around our homes. In other words, Tv as TV works.
Which leads to the solution.
Move the video cloud to the node and encode and insert into the traditional video distribution systems.
Rather than Hulu sending its video directly across the net to your PC, and let the end user figure out how to watch and distribute from there, it should send it to a box hosted
by your cable/telco and possibly even satellite provider, which then transcodes the video and places it on the existing TV distribution system and sends it across a channel
branded with your name and the name of the file to your TV.
The net result is that having subscribed to this "Internet Video to your TV" system for a buck or two per month, you will notice that on your electronic programming guide there
is a subset of channels with your name on them. When you click on a video at your favorite site, that video can easily be rerouted to the server at the node, transcoded into the
right format and shown on your TV's programming guide as "mark cuban channels" - 001 Diet Coke and Mentos -002 Cat Flushing Toilet 003 - Softball game, etc. All you have to do
is watch cable/telco/sat TV like you have always watched tv. Watching video anywhere in your house will be that easy.
Of course it will take coordination between the video sites and the video distributors, but that really should be easy. Even FTP would get it done.
This approach should result in a far better use of capital for them, and more importantly, it moves video off of the last internet mile, where bandwidth is constrained, to their
new Switched Digital Video last mile , which is far less constrained now, and should quickly become completely unconstrained for long tail content.
if done right, it could also replace all local DVR storage. If you think about it, its pretty stupid to have redundant storage in every home. Paying for those ever growing hard
drives, even with falling cost per bits, adds up to a lot of money . Moving that storage to a video cloud at the node or even on the backbone would make set top boxes smaller,
cheaper and more flexible. The Network DVR , with space for remotely loaded internet video should be the way of the future.
In addition, this approach could expand our ability to customzie our TV viewing experience. Why cant we create playlists of our favorite shows? I personally would love to create
a playlist, customized with a picture of my daughter, her name as the channel name, with a playlist or on demand list of shows that are appropriate for her. When there are
videos of group activities like her ballet recitals, it would be great if we could mark the video as sharable with others we designate, or other parents could do the same, and
we could easily watch them on our TV.
The video distribution networks already in place are designed to move gigabits of data simultaneously to millions of homes. As these distribution networks go to IP and Switched
Digital Video, they will be able to integrate back to internet sites and to interact and offer more advanced customization and cloud based applications with far more
sophistication and flexibility than the internet and the web can offer around video. As middleware like Tru2Way becomes more popular, and more TVs support it, the applications
on our TVs will multiply quickly.
There is no reason to re invent TV over the net when TV distributed as TV works, and all the technology is in place to move video from the net to TV distirbution networks.

Top 15 Ways to Extend Your Laptop’s Battery Life
Laptops tend to lose their charm quickly when you’re constantly looking for the nearest power outlet to charge up. How do you keep your battery going for as long as possible? Here are 15 easy ways to do so.
1. Defrag regularly - The faster your hard drive does its work - less demand you are going to put on the hard drive and your battery. Make your hard drive as efficient as possible by defragging it regularly. (but not while it’s on battery of course!) Mac OSX is better built to handle fragmentation so it may not be very applicable for Apple systems.
2. Dim your screen - Most laptops come with the ability to dim your laptop screen. Some even come with ways to modify CPU and cooling performance. Cut them down to the lowest level you can tolerate to squeeze out some extra battery juice.
3. Cut down on programs running in the background. Itunes, Desktop Search, etc. All these add to the CPU load and cut down battery life. Shut down everything that isn’t crucial when you’re on battery.
4. Cut down external devices - USB devices (including your mouse) & WiFi drain down your laptop battery. Remove or shut them down when not in use. It goes without saying that charging other devices (like your iPod) with your laptop when on battery is a surefire way of quickly wiping out the charge on your laptop battery.
5. Add more RAM - This will allow you to process more with the memory your laptop has, rather than relying on virtual memory. Virtual memory results in hard drive use, and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.
6. Run off a hard drive rather than CD/DVD - As power consuming as hard drives are, CD and DVD drives are worse. Even having one in the drive can be power consuming. They spin, taking power, even when they?re not actively being used. Wherever possible, try to run on virtual drives using programs like Alcohol 120% rather than optical ones.
7. Keep the battery contacts clean: Clean your battery’s metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your battery more efficient.
8. Take care of your battery - Exercise the Battery. Do not leave a charged battery dormant for long periods of time. Once charged, you should at least use the battery at least once every two to three weeks. Also, do not let a Li-On battery completely discharge. (Discharing is only for older batteries with memory effects)
9. Hibernate not standby - Although placing a laptop in standby mode saves some power and you can instantly resume where you left off, it doesn’t save anywhere as much power as the hibernate function does. Hibernating a PC will actually save your PC’s state as it is, and completely shut itself down.
10. Keep operating temperature down - Your laptop operates more efficiently when it’s cooler. Clean out your air vents with a cloth or keyboard cleaner, or refer to some extra tips by LapTopMag.com.
11. Set up and optimize your power options - Go to ‘Power Options’ in your windows control panel and set it up so that power usage is optimized (Select the ‘max battery’ for maximum effect).
12. Don’t multitask - Do one thing at a time when you’re on battery. Rather than working on a spreadsheet, letting your email client run in the background and listening to your latest set of MP3’s, set your mind to one thing only. If you don’t you’ll only drain out your batteries before anything gets completed!
13. Go easy on the PC demands - The more you demand from your PC. Passive activities like email and word processing consume much less power than gaming or playing a DVD. If you’ve got a single battery charge - pick your priorities wisely.
14. Get yourself a more efficient laptop - Laptops are getting more and more efficient in nature to the point where some manufacturers are talking about all day long batteries. Picking up a newer more efficient laptop to replace an aging one is usually a quick fix.
15. Prevent the Memory Effect - If you’re using a very old laptop, you’ll want to prevent the ‘memory effect’ - Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries (which most laptops have) which do not suffer from the memory effect.
Bonus Tip #1: Turn off the autosave function. MS-Word’s and Excel’s autosave functions are great but because they keep saving regular intervals, they work your hard driver harder than it may have to. If you plan to do this, you may want to turn it back on as the battery runs low. While it saves battery life in the beginning, you will want to make sure your work is saved when your battery dies.
Bonus Tip #2: Lower the graphics use. You can do this by changing the screen resolution and shutting off fancy graphic drivers. Graphics cards (video cards) use as much or more power today as hard disks - Thanks Andrew
Update 7/7/07: Bonus Tip #1 to give caution about turning off autosave, tip #8 to change information about discharging batteries - thanks to all who pointed it out. Added Bonus tip #2, Tip #1 to add in clause in regards to Mac OSX, Tip #1 about the spinning of hard drives - thanks to all who pointed it out
