Maximize Your Laptop's CPU Speed

laptopI just discovered that by having a different power scheme in your Power Management Settings, with Intel's SpeedStep setting set in your BIOS, that your laptop will run slower than it's rated speed. I have a laptop and used CPU-Z to check its specs- it was running at 1.6GhZ, but the core was a 2.8GhZ! Geez, what a loss of power! So I read up and discovered that the power scheme needed to be "Always On" or "Home/Office PC".

If you're using a laptop with WinXp, download CPU-Z, and see what the speed is, or just make sure your scheme is set to one listed to get the most from your CPU. However, make sure you monitor the temperature and/or use good cooling options.

Cell Phone Myths & Truths

from Cnet

Last week I received an e-mail that I've received many times over, particularly since I've been writing about cell phones. Just one glance at the subject line, "5 Things You Never Knew Your Cell Phone Could Do" and I knew what was inside.

If you have an e-mail account, I'm sure you've received this e-mail at least once. It probably came form one of your "forwarding friends." You know who they are--they mean well, but they insist on forwarding every chain letter and spam e-mail they receive.

Unfortunately, this specific e-mail is hardly worth the time it takes to open it. While it is true you can get free directory assistance by dialing 1-800-FREE-411 (you'll still use calling minutes and you have to listen to a bunch of grating ads), and that a GSM phone's IMEI can help if your handset is stolen, the other three tips are not only completely ridiculous, but also kind of annoying.


Your phone as a key
The most preposterous tip promises that you can unlock your car door with the magic of a cell phone. It goes something like this: "If you lock your keys in the car and the spare keys are at home, call someone at home on their cell phone from your cell phone. Hold your cell phone about a foot from your car door and have the person at your home press the unlock button, holding it near the mobile phone on their end. Your car will unlock. Distance is no object. You could be hundreds of miles away."

Even if the e-mail says something like "It works fine!", this is pure fantasy. Keyless entry works on a radio frequency, and a radio frequency cannot travel over a phone line. Also, as anyone who has a car with keyless entry can attest, you have to be close to the car for it to work.


Magical battery life
This tip, which promises additional battery life for your cell phone is so bad, it's laughable. "Imagine your cell battery is very low. To activate, press the keys *3370#. Your cell phone will restart with this reserve and the instrument will show a 50 percent increase in battery. This reserve will get charged when you charge your cell phone next time."

No, this does not work, and I don't think that I have to justify why not. I'd only say that if this was really true, why would cell phone manufacturers keep such functionality secret? And if it was true, don't you think they'd just include that additional battery capacity in the first place?

Emergency!
Do you have an emergency? If so, be careful when reading this tip. "The Emergency Number worldwide for Mobile is 112. If you find yourself out of the coverage area of your mobile network and there is an emergency, dial 112 and the mobile will search any existing network to establish the emergency number for you."

This is both true and false. The 112 number is the emergency number for European Union countries, but if you dial it on a GSM phone while in the United States, your call will be redirected to 911. Indeed we tried it on both an AT&T and a T-Mobile, phone and we got through. On the other hand, it doesn't work for CDMA phones from Verizon Wireless or Sprint. And I have no idea of it will work in other non-EU countries. In any case, you're better off dialing 911.


From Snopes

The claim that pressing the sequence *3370# will unleash "hidden battery power" in a cell phone seems to be a misunderstanding of an option available on some brands of cell phone (such as Nokia) for Half Rate Codec, which provides about 30% more talk time on a battery charge at the expense of lower sound quality. However, this option is enabled by pressing the sequence *#4720# — the sequence *3370# actually enables Enhanced Full Rate Codec, which provides better sound quality at the expense of shorter battery life.


Claim: Can you cook eggs or popcorn with cell phones?
Verdict: FALSE

Eco-friendly Bulbs Contain Toxic Mercury

By MARTIN DELGADO
from Daily Mail


fluorescent bulbDanger: The new eco-friendly light bulbs contain toxic mercury (picture posed by model)

Energy-saving light bulbs are so dangerous that everyone must leave the room for at least 15 minutes if one falls to the floor and breaks, a Government department warned yesterday.

The startling alert came as health experts also warned that toxic
mercury inside the bulbs can aggravate a range of problems including migraines and dizziness.

And a leading dermatologist said tens of thousands of people with skin complaints will find it hard to tolerate being near the bulbs as they cause
conditions such as eczema to flare up.

The Department for Environment warned shards of glass from broken bulbs should not be vacuumed up but instead swept away by someone wearing rubber gloves to protect them from the bulb's mercury content.

In addition, it said care should be taken not to inhale any dust and the broken pieces should be put in a sealed plastic bag for disposal at a council dump – not a normal household bin.

None of this advice, however, is printed on the packaging the new-style bulbs are sold in. There are also worries over how the bulbs will be disposed of.

Under new regulations for hazardous waste, councils are obliged to recycle them.

At present, they should be placed in special bins also used for batteries at a council dump. But in future, councils will have to provide a collection service or install special recycling banks for the bulbs.

There are fears that without a proper disposal system, the mercury content could contaminate water supplies.

But disposing of one municipal recycling bin full of bulbs costs about $1,267/£650 each time, adding to fears of higher council tax bills.

The warnings cast a shadow over Government plans to begin phasing out traditional tungsten lights this month.

Ministers hope that using the more environmentally friendly bulbs will save at least five million tons of carbon dioxide emissions every year.

The bulbs are due to become compulsory in homes in four years.
Campaigners are calling for an opt-out so that people with health problems can still use old-style bulbs.

Others are thinking of hoarding the familiar pear-shaped bulbs so that they can keep on using them even after they have disappeared from the shops.

Independent environmental scientist Dr David Spurgeon warned yesterday: "Because these light bulbs contain small amounts of mercury, they could cause a problem if disposed of in a normal bin.

"It is possible that the mercury could be released into the air or from land-fill when they are released into the wider environment. That is a concern, because mercury is a well-known toxic substance."

And dermatologist Dr John Hawk, told BBC Radio 4's Today programme that some people already find it difficult to tolerate the fluorescent-strip lighting that is widely used in schools and offices, which works in the same way as the eco-friendly bulbs.

He said: "Fluorescent lights seem to have some sort of ionising characteristic where they affect the air around them.

"This does affect a certain number of people, probably tens of thousands, in Britain, whose ailments flare up just by being close to them.

"Certain forms of eczema – some of which are very common – do flare up badly anywhere near fluorescent lights, so these people have to just be around incandescent (old-style) lighting."
