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.

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
