 whats the latest BIOS version of Ideapad y570?

My specifications of Y570 are i7-2670qm,8gb ram,64gb ssd+750gb hdd, Nvidia gt555m+ Intel HD.

Secondly i have ideapad y570 which came with a charger model 41a9734 which is bulky and short wired.I also have a ideapad z570 with a charger model adp-65kh b which is slimmer and has a longer wire.i am wondering if i can use the same charger for my y570 without damaging the battery or motherboard,because it might have different power input and output.

thank you

Re: Y570 BIOS

Hi Azzuri,


The latest Y570 BIOS available from Lenovo Drivers & Downloads page is 47CN28WW.


Your Y570 is a powerful machine therefore it requires a powerful bulky 120 Watts power-supply/charger unit.

Please do not substitute with a small undernourished charger that will not be able to always supply the laptop with

the needed amount of power and could even cause damage due to overheating.
