Hello:
I have a Lenovo B575 laptop 32 bit, 6 GB ram running on Windows 7 Home Premium. I am looking for a pre-owned AC adapter, as I can't seem to find a new one on Amazon or the Lenovo site as the laptop is not new. I did manage to find someone who has a universal adapter(20 V., 3.25 A, 45 W.) and I am wondering if that would be compatible with my laptop.
