IdeaPad Z710 ''The power adapter cannot supply enough power...''

Hello,

 

i dont speak good english, sorry.!

 

I bought a lenovo ideapad z710 2 weeks ago. I have these problems:

 

1) when i plug in the power adapter, it shows me this message: '' The power adapter cannot supply enough power. Use of this adapter may lower the system performance.''

 

2) Battery life is no longer than 2 hours (manufacturer says this model's battery life is longer than 5 hours)

 

3) If, when i charge the laptop,its in shutdown mode all its ok.... but if its running after 1 hour charging, transformer is getting hot.! ( i think this problem is not as important as 1&2)

 

Please i need your help because i use this laptop for my excersises in university..
Thanks.!

What are the specifications of your Z710?

How much Watts does your AC adapter have?

You should have at least a 90W (dual core) or 135W (quad core) AC adapter.

Maybe you need a new AC adapter if it's faulty.

Warm regards,

I have the same problem, just called Lenovo tech support and they are sending me the correct 135 w power supply. Very good customer support!

I've been running with the same setup for almost one and a half years now, without any issues. I've always thought that the charge-times were quite long, but nothing "serious". That being said, my laptop is beginning to give me that exact error message. I'm using a 90Watt adapter :-/ What do I do?
