I live on a sailboat with limited electricity generation so I need a very low power computer. I have heard that some Everex laptops use 1/4 of the power of normal laptops; does Bestbuy carry these models? What laptop that Bestbuy sells uses the lest power?

Re: low power laptop
With just about any laptop aprox 100w continuous is needed to power one. As long as you have an extra 100w you should be fine with about any laptop, but I'm sure you are familar with adding up the useage for your generator.
As far as power usage on BestBuys models you will have to go to your Bestbuy and get that data. I looked online and they don't list the power usage.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Technician (only for users in the US for now) and get all the help you need. Goodluck!

I have yet to see a laptop that plugs directly into the mains - they mostly use an inline power supply to reduce the voltage, usually between 12 volts and about 20 volts and this is the highest voltage the actual computer needs. The screen might need more but that will be generated internally.
A particularly sensitive person can feel voltages as low as 20 but most folk need around 40 volts before it can be felt. The power light is an led requiring a voltage of between 0.8 and possibly as much as 2.8.
In theory it would be impossible for you to receive an electric shock from your laptop and even if the power supply had become leaky which could make metal components "live", the light and the surrounding material is made of insulating plastic material. If the laptop is running on the battery this possibility is eliminated.
You can check for the presence of shock-level voltage there by using a neon mains tested screwdriver or an analogue multimeter with the black probe connected to ground. If no voltage is found to be leaking around the light the answer might be a static discharge...
Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board. The
LCD cable transfers data signal from the motherboard & video card
to the LCD screen. It also supplies high voltage DC power to the screen
inverter board. The screen inverter board works as a power supply for
the backlight lamp mounted inside the LCD screen. It converts low
voltage DC power to high voltage AC power needed for the backlight lamp
be very carful many sites related to Everex are linked to a bad links and you need to use Firefox to scn them for oyu before you get in...you may find a site soon as I heard that they are trying to get one up next week
The Everex SA2052T uses the same battery as a Averatec 2260 (2200 series) laptop. I purchase one from provantage.com this week. The battery is made by BTI and the model number is AV2200. It works perfectly.
