Antwoord op "Vaio laptop suddenly shutdown?"I have been dealing with this issue for quite some time. Cleaned everything. Replaced fan. Replaced MB. Replaced CPU. Replaced DC jack. Replaced Lan cable (different issue). Total reformat and reinstall. Have it working now but only with switchboard and on/off switch hanging out of case. When I reinstalled the switchboard cover it would die. Check your on/off switch and switchboard if you have one.
