I get nothing significant when I search using the model you stated.
Did you make a typo ?

Have you, or is it possible anyone else has
- dropped this laptop ?
- spilled liquid on it ?

Was it a new computer when you bought it, or a used one ?

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

What's your interpretation of "new"? When did you buy it ?
Laptop main batteries usually work as they should for a year or so, then they begin to rapidly deteriorate. From what I've seen, by two years they cannot be charged to anywhere near their full capacity, and it gets worse after that.
They often develop internal shorts when they are older. If the battery gets HOT rather than just warm after you have attempted to charge it for at least a half hour, or after you have been using the laptop for a while with the AC adapter plugged in, it's definitely internally shorted and you must replace it. Internally shorted batteries getting too hot have been known to cause the laptop to catch on fire.

Some say modern laptop computers should work fine when connected to only the AC adapter - but I believe they often can't. Whether your model can or can't I don't know.

If it's still under warranty take it to a local laptop place that is authorized to work on Gateway laptops and have them analyze it.

If it is not still under warranty see the info I pointed to. You MAY be able to find a free or cheap service manual on the web for your model or model series.
If that doesn't help, then do the same as the above.

The data on the hard drive is probably okay, and you can connect it to another computer one way or another and copy whatever data you want to off of it.

It should still be under warranty. Get it fixed at Gateway's expense. You are often allowed to have a local authorized place do the repairs rather than having to ship it some place. Check that out on the Gateway web site.
If it must be shipped some place, if you need personal data off the hard drive you could copy it before the laptop is shipped.
