This is not good. No CMOS battery or CMOS / BIOS reset jumper to use. Factory / Lenovo staff absolutely no help. No masterpassword for the BIOS provided. No help on providing a copy of the service manual via email.
Lenovo staff generally clueless and unhelpful.
Bad company to deal with. Round and Round and Round in CIRCLES for ever.
I am told that according to "them" the only option is to send the laptop back, for them to throw out the motherboard and put in a new one - charging me almost the same price as a new laptop.
Being a lawyer, - I say Law Suit.
So either post me a mater password to my email address because I will exercise my legal skills and shred this company and advertise it all over the web.
