power outage and damage

i leave my battery out and i only use a/c, if a power outage happens will it damage the laptop?

 

They got this new product, it's called a surge protector. You might want to check it out. More than likely, nothing will happen, but it's no guarantee.

 

The battery acts as a sort of UPS, especially if all power is filtered through it (not necessarily). Unfortunately, it is still an important part of the laptop, and if it fries then you're out of luck just the same.

I forget, one laptop company offers surge protectors when ordering a laptop...maybe lenovo. Belken et al sell travel surge protectors.

 

what happens in terms of windows, will it cause any problems?

 

Instead of a surge get a power conditioner if you are worried about it. CyberPower makes reasonably priced conditioner/surge protectors. Less expensive than APS or TrippLite.

 

Well, if you're actively working on anything like a document or a spreadsheet at the time, you'll lose anything that hasn't been saved. As far as Windows itself, there's always the chance that files will be corrupted.

My opinion has always been that my data is more valuable than the battery.

 

There seems to be some confusion. Electrical problems are more complex than this.

In a blackout, the laptop will stay on as long as the battery is charged, and documents won't be lost. In a surge or spike, the laptop can be damaged, potentially losing unsaved data and damaging the hard drive. In a brownout, the laptop can also be damaged, but potentially less if the laptop is designed to be powered through the battery while being plugged in. Software can be altered when HDD writes are interrupted.

A UPS will do nothing more to protect the laptop than a surge protector would. The power conditioner will prevent damage from spikes, surges, brownouts, etc. Some UPS models have a built-in power conditioner which powers things through the battery (rather than quickly switching to the battery in a blackout), and that is usually labeled Automatic Voltage Regulation (APC's term IIRC), or various other acronyms.

Put simply, if you have unreliable power or valuable data, buy a UPS with AVR for home desktops, a power conditioner might be cheaper for just a laptop, and bring a travel surge protector when away from home. A surge protector won't protect from the most likely damage (a brownout sag), and the protection they offer gets worse with use as the mechanism degrades, but it probably is a good idea to have one.

 

Well..I use this... http://www.amazon.com/gp/product/B00000J53F/ref=dp_cp_ob_title_1
