Greetings to all!
Sorry for my english with a translator. I recently judged the laptop for trying to open descryptors but I did not succeed.
Ok- I thought. Then at least I gonna change thermal grease. BIOS version was 2.09 ACER_E1-571G_v2.09_SLIC_2.1.rar at that time. Gathered laptop and flashed version 2.17 from off site, and found that the nvidia graphics card is not displayed in the BIOS. In the Main tab just None beside VGA bios version (PEG). Tried to do roll back to version 2.09 ACER_E1-571G_v2.09_SLIC_2.1.rar which had always worked, USB flash drive is blinking for about 6 times and then restarting. The BIOS version remains the same 2.17. What is this? I crashed bios or video card died?
ps. remembered that before I tried to reflesh bios with FPT tool -biosrefl
