i have no manage now this problem.if u have any tell me.ok
i have 2 laptops. the first one is not recovering from backup. the second one is ok after flash. the laptops are identical. on the first one i desoldered the chip from the board. the second one i flash with programmer straight on the board. so the issue seems to be heat related for me
 
Hi admin, i have the problem with "this device belongs to...". I change 8 and 16mb bioses and clear me region. Laptop works fine when install the windows and message not come again, but after 3-4 restarts start to blinking caps lock and make sound 3 long 2 short times and no display. I think this is not the right bios from first post, i check that the region of the old one and the new is not the same. Any ideas what to do?

It is very difficult to judge directly and test all components
