Tips on how to prolong your laptop battery life

This applies to any device that uses lithium ion batteries (i.e. laptops, smartphones).


  1. For lithium ion batteries, you do not need to discharge them fully and recharge constantly. Since they don’t have the same "memory" as older nickel-metal hydride batteries, it is actually better to discharge a lithium ion only partially (10 to 20%) before recharging. You need to do a full discharge only about every 30 charges (usually around every 2 to 3 weeks).
  2. Consider taking your battery out when using your laptop plugged into AC power. Just make sure to keep the contacts clean. If you need to clean them, use a lint-free cloth moistened with rubbing alcohol every couple of months.

Software & Hardware

  1. Defrag your hard drive regularly
  2. Dim your screen to the lowest level you can tolerate
  3. Close unused programs running in the background
  4. Disable WIFI when not in use.
  5. Hibernate your computer, not standby.


  1. Avoid propping your laptop on a pillow, blanket, or other soft surface that can heat up or block cooling fans.
  2. Clean your desk. It sounds strange, but if you have a dusty, dirty desk, that dust will get into the vents and clog the cooling fan. Once the dust is inside your laptop, it is much harder to remove. You can try blasting it out with canned air, but you run the risk of damaging internal components. You can also remove the vent and clean out the grit, but remember that taking apart your laptop can void the warranty. So clean your desk at least once a week, if not daily.
  3. Try not to store your laptop in a place where the air temperature exceeds 80 degrees Fahrenheit, such as a hot car or an outdoor patio. And if your laptop heats up or is cold, let it return to room temperature before starting up.
  4. Use a cooling pad when using a notebook computer on your lap.

Easy jailbreaking of iPhone 3G

I did it using Spirit on a Mac.  It’s definitely easier now than the iPhone OS 2.x era — that is, no more of setting the phone in “Restore mode” and running a bunch of commands.

This time it was as easy as downloading, running the app, and clicking the “Jailbreak” button, which, by the way, took less than a minute to complete.  Once done, the iPhone will reboot and it’s back to normal.

Check it out. Happy iPhone’ing!

Create custom ringtones for the iPhone with your Mac

I found instructions on how to create ringtones via iTunes, but found an easier way using GarageBand.

These instructions, BTW, only work on a Mac.

I’m not going to include the nitty-gritty details, but all you have to do is:

1. Open GarageBand (4.11) and iTunes (7.5 and up).
2. Drag-and-drop the song you want to turn into a ringtone.
3. Turn on “Cycle” and set the start end end times (usually 30 seconds).
4. Click on Share | Send Ringtone to iTunes.
5. You simply need to sync the Ringtones with your iPhone and that’s it.

Enjoy and choose an awesome ringtone, please.
