Summary of change:
Back to MembersPage/NanassyPeter ----- '''PC related links''' * VemsTune * http://vems.hu/vt/help/index.html * Old: ** Read the updated manual under the DocsPage or MembersPage/JohanEriksson/VerThreeFirmForDummies. ---- '''PC power supply and motherboard automatic switchon''' It seems likely that the '''PC motherboard's automatic switchon function causes voltage spikes on 5V and 12V lines killing SSD drives''' * and possibly other harddrives, even motherboards and other PC hardware, after 20-30 powerups, possibly later or sooner. Probably most PC power-supplies (not just the cheap ones) are not tuned/tested to regulate properly when switching on at 80V input cap and charging in 10-30 msec to 300V (more likely to cause problem with 230-240V mains than 110V). * '''Solution: do NOT enable the motherboard automatic switchon''' function unless the powersupply is known to regulate properly at the sudden voltage climb of the power supply input capacitor. ** BIOS programmers: apply 200 msec delay before the "immediate powerup switchon"
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
