Is it worth changing to them?A: LED lighting is indeed the trend of the future.LED (light-LEDs) higher cost of bulbsMore efficient than the CFL (compact fluorescent), they last longer, they turn on immediately (the CFL takes a second or two) and are better for the environment because, unlike the CFLs, they do not contain toxic mercury.Since CFLs are designed to last at least a few years, it doesn\'t make sense to throw them away --Unless the light from the led makes you happier than the light from the CFLs.This difference is hard to describe but you can look at it yourself by comparing the LED and CFL in the lamp you \'ve been using (remember that the lampshade will have a big impact on the light ).If you decide to switch to LEDs, three-pack of 60-watt-You can get the same light bulb for about $20.Q: I recently accepted a free trial of Microsoft Office 365.I refused to buy $99 after the trial-a-Let me continue my one year subscription with the softwareMainly because I have never used any app except Word.The problem is that after that, I can no longer access the document I created in Word.You heard of this powerful one.arm tactic?Is there a way to get my file back?A: I think Microsoft treats expired trials the same way it handles expired subscriptions.Office applications, including Word, will enter restricted mode unless you pay, allowing you to view or print files without creating new documents or editing existing ones.The document you saved in Microsoft one drive (previously SkyDrive) should still be accessible and you may be able to use the third-Party word processors open Word documents stored on your computer.Speaking of the thirdIn addition to Microsoft Office, there are some great free software.I suggest LibreOffice and I use it to write this column.You can download it at www.libreoffice.org.Q: I\'m thinking about buying a used laptop.Would EBay or Craigslist be a great place to see?Because if you buy it from an individual, there is no way to know if there is a problem with the hardware or the operating system, which will appear after you receive the computer.Instead, I will buy a refurbished laptop at Wal-Mart.com.They sell new brands.Name the model of Windows 7 or 8 for less than $300.You can buy a laptop online and then buy it in the nearest store.David Einstein is a free writer.Is there a question about personal technology?E-mail: einstein.dave@gmail.
