Hello, I did a fresh install of Win 10 on this laptop (without upgrading bios, dumb me) and when I got to the desktop, battery died. I plugged it in and tried to turn it back on but nothing happened, i thought it was drained so I waited few minutes and tried again. Nothing happened. I tried everything I could, I switched ram, held power button without battery and charger connected even for 2 minutes and nothing. Every time I tried to run it I heard CD/DVD rom doing something (probably moving this part with laser) and hard drive LED was on but not flashing or anything but it only happens if I hold the power button for a few seconds or plug in the adaptor while the battery is in. Charger isn't original and I don't really have a possibility to get a new/other one, but I'll be satisfied enough if this can be diagnosed.
