Review of Dell Inspiron Mini 9 Laptop Computer (Intel ATOM N270, MB)

Last year, the world of budget notebooks was turned on its head with the introduction of the ASUS Eee PC: A 2-pound laptop with a 7-inch screen and a starting price below $300. Prior to 2008, "budget notebooks" were bulky, overweight 15-inch laptops while "ultra-portable" notebooks commanded a premium price well above $1,000. In no time at all terms like "budget ultra-portable," "subnotebook," and "netbook" became part of the techno-geek vocabulary. Every notebook manufacturer on the planet (even some that you might not know) scrambled to create their own "netbooks" ... and Dell has finally joined the party.
The Dell
Inspiron Mini 9 is an 8.9" netbook with a $349 (Linux) or $399 (Windows XP) starting price and some impressive features. Dell was kind enough to supply us with a pre-production copy of the Inspiron Mini 9 so that we can conduct in-depth testing and let you know if this netbook really is "your new best friend" ... or just the weird kid you try to avoid on the bus. Finally, we draw conclusions and lists pros and cons as follows:

Pros
Small and light
Easy to use
Very well built and durable
Responsive Synaptics touchpad
Easy to upgrade RAM, SSD, and wireless cards
No noisy cooling fan
Low price for an ultraportable


Cons
Gets a little hot
Glossy plastic lid is a magnet for fingerprints
No F11 or F12 keys, other function keys in strange location
4-cell battery is nice,
6-cell battery would be better

How 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 are 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
Notebook-battery.org.
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. Since we have more new and efficient laptops in markets : hp pavilion dv2000, hp pavilion dv6000, dell inspiron 6400, hp pavilion dv9000, more hi-capacity replacement laptop batteries for hp dell notebooks.
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.
