I have a client with a lenovo x200 laptop and was replaced with a new laptop and are looking to reinstall the laptop and use for home use. The problem is that the laptop will not recognise the fact that there is an external dvd drive connected to reinstall and there is no recovery partition.
In the BIOS the external USB drive is disabled and greyed out because it is in user mode and do not know the admin credentials to access this to enable the dvd drive.
I have taken out the cmos battery inside and left disconnected to laptop for around 20/30mins without any luck. Whenever I boot up the machine now it is asking for a BIOS password and the usual 3 attempts and its locked until you turn off and boot up again to try again and so on.
I have tried a few back door passwords without any joy. I have read that you have to send to lenovo to resolve as these details are not stored in the cmos battery like other pcs and laptops as it is stored in the eprom chip.
Is this true and is there any way this BIOS password can be removed without having it shipped to lenovo to resolve?
Thanks in advance
