||| Hi Jim Macklin:
||| Thanks all the help. I truly appreciate your
informative
| response on
||| this regard.
|||
||| As to the Laptop, I just purchased it a week ago, then
| it's new.
|||
||| One thing over which I concern is, ... since the day I
| started to use
||| the Laptop, I mostly depend on an Adpator. I rarely use
| 'Battery,'
||| in fear that a life of Battery could shorten. However,
| it sounds other way
||| around, ... 'shorten' its life if not use the Battery.
| Should not depend on
||| ONLY an Adaptor, it that correct? Or, can I use an
| Apator with taking-off
||| a Battery? This might be a bit 'silly question' to ask,
| but, ...
|||
||| Then, in my assumption, I should use both an Adaptor and
| Battery
||| alternatively,
||| like a Battery when use it in the upstair and an Adaptor
| when using in the
||| downstairs.
||| Normally, I use the Laptop for about two-hours' period
| that might be a
||| problem?
|||
||| Your opinion on this would be appreciated.
