- Are there any problems running a typical laptop all the time, plugged
- into the AC power (e.g. a BBS or home control system)?
-
- In particular, in an area with lots of thunderstorms (Boulder CO)
- where power surges and 1-second outages seem somewhat frequent, do you
- need a UPS, or just a good surge protector (MOV or "zero surge" or
- ??), or does the AC adaptor/laptop battery insulate you from those problems?
-
- E.g., is the laptop running off the smooth power flow from the
- battery, while the AC adaptor trickle-charges the battery? In that
- case it seems that the most you might risk would be a fried adaptor,
- unless the power was off for longer than the battery life.
-
- If you need a UPS, are there tiny ones sized to the modest requirements
- of a laptop?
-
- If it matters, I'm thinking of getting a TI 4000 486SX/25 system.

- Thanks,
