Tip & How-To about Computers & Internet
My kids Acer extensa would not power up, front power lights go on for a couple of seconds then go off leaving us with a dead laptop ready for the trash, I followed the tip to disassemble the laptop completly and reasssemble my thinking was why not its dead anyway? so I did and guess what it worked. I think the biggest reason this worked is because of the removal of the battery CMOS caused a hard reset therefore clearing Main board boot logic this allowed for laptop to boot and work again. So far so good its been 10 days. The first tests I made where to check the power supply for voltage with a digital voltmeter and paper clip to probe the center of pin terminal for 19.0 volts dc. My second test I made prior to dissasembly was removal of battery, hold down the power button for 30 seconds for a soft reset. the laptop should power up with the battery taken off the laptop in my case it did not, so I said lets dissasemble, while I was there I removed the battery that retains CMOS memory on the main board and checked for over 3.0 volts that tested ok. I did not see any abnormal wiring or mainboard issues or odors! all visual looked perfect so I proceeded to reasemble and laptop booted. All tips vary by laptop and if problem is software or hardware but this one worked for me so far, thanks for all the great tips out there keep up the good work!
