Battery Guide - how to charge laptop battery
1: Recharge your laptop's battery whether the battery is fully drained or not. Especially if your laptop is using a li-ion battery, it makes no difference.
2: Heat is your battery’s worst enemy. Avoid charging your battery in hot places such as your car during the daytime.
3: A full discharge puts more strain on your battery than several partial discharges. You do not need to worry about battery memory with Li-Ion batteries. Get into the habit of recharging the battery when it reaches 10-20%.
4: If you will be on AC power for an extended period of time, you can prolong your battery’s lifespan by removing it and putting it into prolonged storage. Allow a stored battery to warm to room temperature completely before using or recharging it.
5: Calibrate your battery’s fuel gauge by doing a full discharge every 30 cycles. Run the battery to the cut-off point in your notebook to keep the battery’s fuel gauge accurate.
6: It doesn’t take longer to recharge the battery if you use the laptop while recharging.
7: Never discharge your battery to 0% – as this can render your battery useless. By short, I mean that you connect the two terminals (positive and negative) directly so that the battery simply drains. This is a very bad, stupid thing to do. It can cause a fire. Don't do it.

What is a dual layer dvd burner and how does it work
What is a dual layer dvd burner
Before explain the concept to you, let's talking about dual layer media first. Dual layer media, also known as DVD-R DL, means that much like commercially pressed DVD-ROWs, these recordable discs have two layers of dye, almost doubling the size of older DVD5 format to 8.5gb.This is a recordable DVD9 format. Only dvd burners with dual layer DL DVD R Media compatibility are able to burn the Dual layer media. This is what dual layer dvd burner is. If your dvd burner does not have the capabilities, it is possible to be upgraded to burn daul layer media.
Dual layer DVD technology
Dual-layer recording (sometimes also known as double-layer recording) allows DVD-R and DVD+R discs to store significantly more data-up to 8.54 gigabytes per disc, compared with 4.7 gigabytes for single-layer discs. Along with this, DVD-DL's have slower write speeds as compared to ordinary DVD's and when played on a DVD player, a slight transition can be seen between the layers.
Dual layer DVD technology is not new. Commonly called "DVD9", Hollywood has been churning out major motion pictures on stamped dual layer dvd discs for years. How else could they include the full length movie plus all the bonus materials commonly found on today's DVDs? Because dual layer technology has always been part of the dvd specifications, dual layer DVD recording on the desktop is the natural progression of single layer 4.7GB recordable technology.
How does it works?
When a dual layer recordable disc is inserted into a dual layer-compliant recorder, the optics will focus the laser at one of the dual layers to try and detect an “Address In Pre-groove” (ADIP) signal. From the ADIP signal, the recorder can detect whether the disc is dual layer and which layer it’s focused on. Once the media type and the layer are detected, the laser will be able to move its range of focus down or up to access any one of the two recordable layers. The drive will then focus on the Lead-In area of the disc to determine whether the disc is completely blank, partially recorded in Multi-session format, or Finalized (completed).

What is the best hdmi cable?
What is the best hdmi cable for use in HDTV,home Theater,and business class projector based applications?
Here is Shadowself's personal experience using cables over the last 30 years, maybe these tips can help you:
1) Never buy cheapest cables you can find.
2) If you are running short lengths(short compared to the "standard" for that cable type/use, for example, some cable standards specify no more than 1.5 meters, some specify no more than 10 kilometers,etc.) then a generic, run-of-the-mill cable is usually just fine. Again, just don't go cheap.
3) If you are pushing up near the high end of the length as a funtion of the standard(e.g., going the full 1.5 meters when the standard specifies an upper limit of 1.5 meters) then get the best cables you can. Even if you have to pay a couple extra dollars per cable.
4) If the "standard" is new (for example, HDMI 1.3 which has a higher bandwidth requirement than HDMI 1.1,1.2 or 1.2a) then only get cables that you can return if they don't work (don't get stuck with non functional cables). A lot of cables run on the ragged edge of standards compliance for brand new standards.
5) Figuring out definitively if any transmission problems are due to the boxes, connections or cables is never easy unless you have a time domain reflectometer in your pocket (or know how to make one out of a signal generator, digital oscilloscope, etc.) so eliminate one possible headache and go for good cables. Think of it this way, if you are connecting a $1,000 box to a $4,000 box does it make sense to try and save $25 or $50 on the cabling?
In my experience, a decent hdmi cable is a decent cable. It needs to accurately carry the signal put on it, and it takes a lot less than some would like you to believe to do this. That doesn't mean 'cheap and cruddy' - it means inexpensive, but decent.
Finally, I suggest you buy hdmi cable from www.gogo-power.com, one that just works very well and is a great price.
