So yesterday I was working on my company's laptop when my personal laptop (asus g751j) just died with no warning (I wasn't doing anything on it). It suddenly shut down. I tried to turn it back on but it's dead. The LEDs show no reaction.
The laptop's battery has been dead for years and never recharges but I left it in the laptop anyway since I don't use the laptop outside the desk.
So I tried to remove the battery (and it wasn't easy in this laptop model) and use the plug directly because I read somewhere that a bad battery may prevent the laptop from starting but still doesn't turn on. I also tried to leave the power button pressed 40 seconds and then try to use it with the plug.
It could be the power supply? Also, I have a spike protector outlet and it's not that old...
Any ideas on what I should do?
I could try to buy another battery to replace this one but how can I know if it will fix the problem?
