HP Compaq Business Notebook 6710b Battery

Which is better, dell mini 10 or hp mini 10? I'm trying to help someone choose between the two and don't know much about computers, the only specifics i have is what i mentioned above and that they want a webcam with it.
I have a verizon samsung intensity phone, its small, its slides. And today in the morning i had class and i got iced coffee before. I let it sit in the car holder until class finished HP Pavilion dv6700 Battery and came back. In the afternoon i put my phone where the ledge was underneath the cup holder and it was a little wet so i toko my phone away form there immediately and the back of the phone [where the battery is] was a little wet so i wiped it off and on the front it was a tinny bit wet so i wiped it off. The phone worked completely fine.completely.

The power button is also the end button on the phone so whenever i pressed end it worked. But when i came home today my phone was off, i don't why. It was in my pocket so maybe. I pressed the power button and it wouldn't turn on. I charged it, and it was charging HP 537626-001 battery but it turned off while charging twice when i tried. I put it back in the charger and its charging fine now. So did the phone just spazz? Because i don't see a reason why the power/end button would be broken? If it worked fine today cuz i used it, and charged it today, is it fine? Its still charging. And this phone isn't a year old and my friend says when i go to verizon they will replace my phone for free. Will they? If its broken?

Which is better-a dell inspiron (desktop) or a dell studio xps (desktop)? I'm having trouble deciding which would be better. Inspiron desktops are cheaper, but xps desktops are a little more expensive and i can't tell what the difference is between the two brands.

 What is a better computer the dell studio 1558 or the dell inspirion 15? Im looking at the HP Compaq Business Notebook TC4400 Battery and dell inspirion 15 for a ew laptop and ive seen mostly good reviews on both. Im not looking for if the computer is worth its price but just for a general overall better computer. Which one would be better.

I have a 4 year old p4 1. 7ghz which my mum uses regularly for word processing etc. Today i went to switch it on as usual and when i pressed the power button it didnt start ! No beeps, no lights, just as if i didnt press the button ! I bet it could be many HP Compaq Business Notebook 6710b Battery differrent problems. But where can i start diagnozing first? I already tried a differrent lead but it didnt solve the problem.
