Okay, so I just bought my SECOND Gateway Platinum Edition Laptop Model MX6450 and have only had it a couple of months and all of a sudden, it does not want to power up. I first bought one brand new from Best Buy when they first came out in 2005, loved it, but after about a year, the internal ac/dc jack solder came loose and eventually that laptop ended up throwing itself at the wall (or so I like to tell people). However, because I loved the laptop and had originally narrowed my purchase of that particular laptop from a list of potential laptops of 20, I wanted another one (yes, I was aware the jack thing was a common issue with this particular model). So, found a good deal on eBay for another MX6450 and received it about two months ago. Everything was going great until the other day, when, POOF, right in the middle of something it shuts off, no warning, no booting down, just there one minute and gone the next. Pulled battery and battery meter (this battery has a little button on the underside and when you push it it tells you in increments of 25 how much battery life is available, well it was flashing 25. Plugged in AC Adapter and indicatory light showed steady charging. After 24 hours, battery still dead. Also, isn't laptop supposed to be able to run off just adapter if there is no battery in it? because it doesn't. However, it is NOT the ac/dc thing like last time, because it is not acting like it did last time, the connection seems stable. Now, if i try to turn it on when it shows the adapter is connected and charging the battery, it gets to the startup screen where it gives you the "Press F2 for advanced startup options' but then pops off again! I have ordered another battery but if anyone has any ideas in case that doesn't fix it, i would love to hear from ya!
