My laptop switches itself constantly off and on,

I would try a factory reset. Make sure you back up all data as it will be lost. If that doesn't work the a new battery would be next. If it continues to act up then you have a hardware problem and it needs to be repaired.

If you are looking for new intercom system then I would suggest you to buy it from http://www.hulksecurity.com/ .Hulk Security System not only provides intercom systems but they also offer variety of access control system, CCTV and alarm systems. Well, I hope this would help you and have sorted the concern for intercom system.

try reseting the router your hooked up to.

No, it's because Windows has been severely corrupted by a virus. Just reinstall it using the Recovery CD that came with the pc when you bought it, it will be as new. And next time use a better antivirus.

Here's something that has worked in the past. Turn the Master ON/OFF switch to OFF. Unplug the unit from the wall outlet and wait 12 - 15 minutes before plugging it back in. Once it's plugged back in turn the Master ON/OFF Switch to ON and set the controls as you normally do.I f everything now functions as it should, the unit reset itself.

If that doesn't solve the problem contact the Oreck Service Dept that did the tuneup for you.

I suggest you talk to Rolex or thier local dealer to see if the slowness you are concerned about is outside the guaranteed accuracy for the watch.

I can't find any reference to accuracy on the Rolex site but other makers have mentioned 15 seconds per month for the accuracy of an automatic watch. This seems poor compared to the accuracy that we have become used to from electronic watches but it is a mechanical watch!

Speaking to the maker might clarify what you can expect from your watch and if it is outside their tolerances, I would expect them to put it right under their warranty.

change the power setting on your laptop to balance

If a computer shuts itself down suddenly after 10-15 minutes it's usually down to oveheating. clean the filters and ensure that there is good airflow around the computer when you use it. you can keep an eye on temperature and control your fans with this program

you might need to buy a laptop cooler like this

How old are those battery's? The below is copyed from http://www.batteryuniversity.com Aging is a concern with most lithium-ion batteries and many manufacturers remain silent about this issue. Some capacity deterioration is noticeable after one year, whether the battery is in use or not. The battery frequently fails after two or three years. It should be noted that other chemistries also have age-related degenerative effects. This is especially true for nickel-metal-hydride if exposed to high ambient temperatures. At the same time, lithium-ion packs are known to have served for five years in some applications. Manufacturers are constantly improving lithium-ion. New and enhanced chemical combinations are introduced every six months or so. With such rapid progress, it is difficult to assess how well the revised battery will age. Storage in a cool place slows the aging process of lithium-ion (and other chemistries). Manufacturers recommend storage temperatures of 15°C (59°F). In addition, the battery should be partially charged during storage. The manufacturer recommends a 40% charge. Hope this helps
