Laptop troubles
hypernova:
Well, realized that no sound was coming out, and I knew I must've forgotten to connect the speakers. (Actually the volume control was disconnected to be specific). So I had to take everything apart again.
Anyway, I'm still having trouble with this thing. Like before, when I first put the battery in, the laptop isn't seeing it. Yet when I pull the power plug, like I just did now, the thing is still on. So if there's no direct power source, and the thing isn't seeing a battery, why the hell am I still typing this?

--- Quote ---Apparently the included Toshiba battery is around 4000 mah. I'd say over the two years we've had it, we've hit that, and most likely exceeded it by as much as another 1000 mah. So I bought a new battery.

uhm, you know mAh is a measure of current capacity - not lifetime right. right? ...
It stands for milliamp hours, think of a battery as a garden worker. the voltage of the battery (7.2 volts or whatever) would be equal to how big the person is and a milliamp is how heavy a wheelbarrow they can push without getting tired. a small child (4 volts) could not carry anything in a wheelbarrow, simply because he is not tall enough to reach the handles. so a bigger person is needed. (more voltage) he is tall enough to reach the handles.
if the person is weak (small mAh say... 2000 mAh), they can carry a small amount of stuff in the wheelbarrow for a long time before getting tired and having to stop... but pile more stuff on the wheelbarrow and they can't carry it as far as before. he gets tired fast.
if the person is stronger (large mAh say 4000 mAh), they can carry a small amount of stuff in the wheelbarrow all around town before getting tired. but again pile more stuff on the wheelbarrow and he can't carry it as far as before, but still farther than the weak person.
with your computer, if you where to draw 4000 milliamps from your 4000 mAh battery, it would last 1 hour before being dead. like wise if you where to draw 2000 milliamps it would last 2 hours, and 500 milliamps - 8 hours.
if you have a 2000 mAh battery you can still draw 4000 milliamps from it, but only for about 1/2 and hour before it is dead.

Well... first off, YMMV.
My problem was with a Dell Inspiron E1705.
My puppy chewed the power supply on the DC side. When the cord is shorted (yes I tried to repair the damaged cord, but it's not the point of the here) the laptop goes into immediate shutdown. Even if the battery is still good, a bad cord forces the shutdown.
It sounds like your problem might be a little more complicated, but I would suggest finding a replacement power supply to eliminate a potential source of problems.

Nope. Didn't know at all. Just assumed since that's how it's basically advertised, especially on ebay. Plus the math checked out.
So are you saying that my 4000 mAh battery drew about 2000 mA/hour? (The battery drained in about 2 or so hours before needing charged.) And that it has nothing at all to do with life?
Anywho, I went to turn it on last night, and nothing. Not even a dang light. Plugged in or not. But it should still work even if the battery's spent and plugged in. It didn't. I fiddled with the cord, and got a few fleeting moments of AC Power light turning on. So there must be something wrong in the cord. I cut it open near the end, and bam! Problem 1 found. The stranded wire that's under the first sheathing has completely become disconnected. So a quick fix until a new cordset comes in is I just folded the cord over on itself to restore that connection, and taped the crap out of it. Works fine right now. Still not convinced the battery is good-I think it's problem 2. I do know that 3rd party battery I just bought wasn't working correctly. Got an RMA to send it back.

Just got the new cord in. Initially, it didn't work. No AC light, nothing. So once again, for the umpteenth time, I start cracking open the laptop, to see if I can find any loose wires or something being wrong. As I'm unscrewing things left and right, I decide to have the cord next to me while I do it so I can see if anything makes a difference. Shortly after disconnecting the keyboard, I decide to plug it in for the heck of it.
I've got the AC light. So it's receiving power. Then I start it up, connect the keyboard, and load up Vista. Shows the battery as missing, so I pop it out for a few seconds (the old factory battery), and back in, making sure to give a stronger press when I put it in. And now the battery is visible and charged.
WTF. I don't understand this at all. I didn't find any loose wires or anything stemming from the power wires, and the battery is connected directly to the mobo. None of this makes any sense. I guess I'll just hope it doesn't give me any more ---steaming pile of meadow muffin--- from here on.
