Y570 compatability with Lenovo 90W Ultraslim AC/DC Combo Adapter

2012-03-24, 2:14 AM

Anyone know how to adapt the Thinkpad Lenovo 90W Ultraslim AC/DC Combo Adapter for use with a Y570?  Bought the ultraslim power supply last year for my two Thinkpads.  Those machines now badly obsolete and switched to a Y570 last month.  Official word from Lenovo is the ultraslim power supply will not work with Ideapd series.  Didn't occur to me that Lenovo would make a basic accessory that wouldn't work accross product lines.  Right now the ultra-slim is a $100, 1-year old piece of junk if there isn't a way to adapt it.  Thanks.

Hi Guy,


please carefully compare the ThinkPad adapter with the OEM adapter that came with your Y570,

the following conditions must be met on the secondary side...

1- same voltage and polarity at the plug

2- same size and type of plug

3- preferably same wattage


I guess the Y570 adapter is a 120 W version,

therefore a 90 W version adapter could only be used under low load conditions with the Y570 machine anyway.


hope this helps... Zehn
