COMPUTER NOT TURNING ON? Constantly dead?

A few days ago I left my computer ( Lenovo Z500) on (by accident) and being low on battery, it died. I thought that I would just charge it and it would turn back on, but for three days now it has been "charging" but won't turn on! Every time I plug in the charger or press the on button, the battery icon on the front flashes red three times. I'm extremely worried and don't know what to do! I thought it was really low on battery, but after three days (and nights?). Please help! I need my computer everyday, and it's only about 6 months old?

Its broke

If its not working then it would be nothing to do with it being on low battery. It may be the end of the battery's life on this planet and you may need to get a new one. I can't actually debug the issue with the laptop make sure that its the right power brick and the right cable going to the power brick. Sometimes the power cable may be the wrong one so check. Also if you can't solve the issue make sure that you contact Lenovo to get your money back or get a repair

Hope it helps and your laptop gets fixed! I know how frustrating it can be!
