Vrata 10 Posted March 3, 2015 Can you please help me with my problem with dell? The laptop normally starts on external monitor (when i disconnect internal one) . But, when i plug external monitor out, and plug in the internal in, it shows screen only for a while (few miliseconds) - it just blinks on bios booting. Can it be BIOS proble? Or its just problem with magnetic sensor, when laptop is closed? Please help to repair this pc. Thank you so much. Quote Share this post Link to post Share on other sites
