Laptop battery wearing down? In this week’s episode of Upgrade Your Life, Yahoo! News’ Becky Worley shows us how to help batteries last longer … and what to do when they run out!
First, the basics
Most laptops use batteries that can last for 3-5 years, or about 1000 charges. (A premium laptop’s battery might last longer.) Every time you charge your battery, the total capacity of the battery is diminished. Originally it may have had a run time of 3.5 hours, but after a year it’ll run out of juice at 3 hours, even on a full charge.
If your battery capacity has diminished, there are a few things you can do about it. To find out what continue over to Upgrade Your Life.
“In December, the FBI issued a warning about a broader category of malicious programs called “rogueware.” These programs appear on users’ machines and claim to find viruses, then offer to clean them for $50. Rogueware looks so realistic — complete with Windows-like dialog boxes and scary warnings — that Web users were tricked into sending $150 million to criminals last year, the FBI says.
The new ransomware is similar, but far more aggressive. Once a computer is infected with it, the program does more than recommend a software purchase –it simply won’t let users continue to use their PC until they pay up.
Luis Corrons Granel, a researcher at Panda Security, said use of ransomware by criminals is exploding — 25 percent of all rogueware in the past quarter involved a family of intimidating products named “TotalAntivirus.” It demands that users pay $50 for two years, $79 for a lifetime license.
“The increase (in ransomware) has been really significant,” Granel said. A single family of ransomware programs called “Total Security” made up one-quarter of all rogueware programs detected during the past three months, he said.” – Source: MSNBC
