Hello guys! I'm having a problem with my Lenovo Ideapad S500 (Geforce gt720, i5 processor). When i'll turn on the pc, everything seems to be good, browsing the internet, watching videos doesn't cause anything. But problem happens when launching some game. It takes about 30 seconds since launching and my laptop just gets into sleeping mode itself. When I'll turn on the PC back, everything runs, game is still turned on, so i must turn it off as soon as possible, because it would turn my pc off soon again. After turning off the game pc runs normally, without problems. But only when I do some easy job. But I noticed one thing. When my PC gets into sleeping mode, it stops charging my PC. After turning it back on it only says: Plugged in, not charging. After unplagging and plugging charger it starts to load my battery again. So it seems like it stops charging my baterry when launching some difficult program. This is also causing that my PC turns off after a while. Laptop has already about 5 years so I was thinking I could fix the problem by buying new battery. What do you think guys? Would it help?
