laptop revival / upgrade causing ghost bootups after standard shutdown

post #1 of 5
Thread Starter 
im giving my laptop (acer aspire 8920G from 2008) a SSD, cmos battery replacement upgrade plus fresh install of windows 7 professional 64 bit. after installing the parts and updating bios. after quite a few windows updates (150+) and acers own drivers from their website, i noticed the laptop will start itself back up after it fully powers off. ive disabled all network boot options both in the bios and in windows, plus all usb / modem boot options as well, ive also disabled restart on system failure. same problem happens with my old hard drive too. also looking at the bios i noticed my serial number is an odd "12345678901234567" followed by in another line the uuid line - 0101010101010101010101. also, letting the laptop go to sleep will cause a failure to shutdown error when it starts itself backup.

i know with this computers age its reaching the end of its service life, but it was an $1800 laptop and was equal to my custom built desktop at the time, and id like to get at least a few more years out of it.

any ideas?

if all else fails i can just unplug the battery / power plug right after it shuts down before it powers back up, thatll keep it off with no noticable problem afterwards like holding the power button will do

Hmmm, that's bizarre. When did you first notice this problem?

Just a thought, did you check the voltage on the CMOS battery? It's possible a bad battery could cause the laptop to kick back on.

first noticed the problem the day after i installed all of the windows updates and i noticed my fully charged brand new battery was dead, no i didnt check the voltage on the CMOS battery before installing it , but its keeping track of the time in the bios. i replaced it because every time i would start the laptop my system time would revert back to 2006 if i didnt use it more than twice a week, we fried our voltage tester last week working on our car radiator fan... i could try using the old cmos battery, i kept it just in case

Hmmm. The safest thing to do is to update your BIOS and then reset everything to defaults, see if that fixes the issue. Also, I know your voltage reader broke but I would check that also, just to eliminate that possibility. Good luck!

success!! i need to stop having multiple variables when i work on my computers, leaving the stock bios settings and replacing the cmos battery to the old one was able to solve the problem, so i plugged the new cmos battery back in, and it still works just as intended, me changing the bios settings was most likely the culprit, makes no sence but then again its a computer.. sometimes they just dont
