So my girlfriend brought me her laptop today because it won't power on any longer. A few days ago her screen stopped working, which turned out to just be a loose LCD cable (took off the screen bezel, pushed the cable back into place, and it worked fine). So I'm not sure if it could be related to that or not.
So far I've tried taking out the battery and leaving it unplugged for a good while, tried battery in and unplugged, plugged in with battery out. Then I took out the RAM, one stick at a time, and tried swapping them around in the different slots. Still nothing. I've also tried using a different power supply (Cooler Master one, with multiple head options) and the battery out, that still doesn't work.
When the charger is plugged in, the battery light turns white, and orange when the battery is in as well, so I assume it's still drawing power/charging the battery. However, hitting the power button does nothing. When I hit the power button the battery light disappears for a second or two, then comes back on. If I hit it a few times in a row, the power light indicator flashes for not even a second, then the battery light comes back on.
My next step is too crack it open and have a look at the power board and the cable to it, to see if it's broken/loose or whatever.
Any thoughts or feedback would be greatly appreciated. Thanks bunches,
