Hey everyone,
To give some back story, I recently replaced my battery and my hard drive (with a faster ssd). My laptop was working perfectly until a few weeks after these upgrades. It is a Lenovo Y40.
So, the first weird thing that happened was, my screen back light just stopped working. You could look really closely and see the computer was running, but couldn't see anything because the back light wasn't on. I powered down the computer, and when I tried turning it back on, nothing happened. After sitting for awhile, it'd let me turn it on. This problem would continue coming back over the next few weeks. I pulled off the back and assured that the battery power cable was plugged in all the way, it is. Now I'm at the point where the computer will sometimes power on, and other times not. This is a huge problem, as I'm a computer science major in school, and I need my laptop. I'm determined it's something wrong with the power delivery. I know it's not the battery, because if I plug in the laptop charger, it still won't power on. If the battery is dead, it should be able to run on power from the wall. Anyone have any ideas? I'd really appreciate some help soon to avoid having to purchase another laptop!
Thanks,
Kyndle
