I am having the worst luck with my computers...And right when I have a bunch of assignments due too!
I just recently built a computer, and it has been working fine for about three weeks. A few days ago, my brother was playing a game on it, and left the computer on for a while after he had finished (I did the same thing a bunch of times). I can't remember whether the computer shut itself off or if I did, just that it was on for a while after the game, and then it was off. Now it won't start.
The motherboard makes no beep. The fans start spinning (CPU and case), then immediately stop. I have left it unplugged for a day and tried to restart it, but that didn't work. As soon as I plug in power, the computer fans start whirring, then shut off, and it does this every time I press the power button. However I noticed that when I flip the switch on and off on the power supply, nothing changes. It only starts when I unplug and plug back in the power cable. Is it the power supply? Would the mobo make a beep even if it was broken? I don't see a mobo LED light up, but I didn't see it on the board either...do they all have one? Any troubleshooting advice would be SO welcome.
Second, and much less urgent, I have about a year old Lenovo laptop that for the last month or so has had a loose wire connection between the wall and the charger. I had to kind of wiggle the thing around to make it work, and it was kind of a pain but I could live with it.
I went away for the weekend and left it plugged in. When I came back, it was still plugged in, but the charger connection light was not on as it had been when I left it. I could still wiggle the cord around to make it light up, but the battery charging light wouldn't turn on, only the battery-charger connection light (which I think means that the battery is fully charged).
I cut open the cord, fixed the connection, and the power cord works perfectly again. However, now my computer can no longer run off of the battery. In power management I can see the battery is connected, it reads a 100% charge, the power-battery connection lights up when I put the battery in, and turns off when I take it out (the computer stays on when plugged in). However, the physical battery charge lights on the laptop are not showing up and as soon as i pull the plug, the laptop turns off. One thing I did notice: right when I turn on the computer, the physical lights show a full charge, then go away. Also, right when I take the battery out and put it back in, the lights come on for a short amount of time, then go away. During these times, if I pull the battery, it still shuts off.
Hope I gave enough information, and thanks for the help.
