I did a fresh install of 7 on an older laptop that had a corrupt version of Vista on it. During the install prosses, when the computer needed to restart, it just hung. I held the power button down, thinking I would have to start over, but when I started it up again it continued on its merry way. After the install finished (having to manually power it down whenever it needed to restart) I was hoping an update would fix what I thoght was a software issue. After it was fully updated (having to manually turn it off when it needed to restart) it still would not fully power down. Thinking it was a bad install, I reinstalled (with having to manually power down still) the same thing happens. When you power down, Windows shuts down, but mother board stays powered up (screen goes black, but all the lights stay lit) it never fully shuts down. I am assuming Windows fully shuts down, because when I turn the laptop back on, it never tells me that Windows didnt shut down properly. I have been through every forum post I can find on the subject, tried every answer they have, but nothing has fixed it. That lead me to this thought. The power supply that came with the laptop, is a generic one with adapters, the owner said the would have to wiggle the jack around to get power, when I first started working on the computer, I could not get it to power up, even when I wiggled it (battery is shot, must be plugged in to power). I took the tip off and the + & – posts were floppy and almost falling out. They had other tips with it, so i found one that fit the laptop (but assuming its not the one made for the laptop) And got it to power up. Can the improper tip, keep the motherboard powered up even if Windows shuts down?
Things I have tried so far:
Reinstall
Safe mode
Clean boot
Disabled non essential devices
Turned off various services
Drivers and BIO/CMOS are all up to date.
Nothing has worked so far. Its an older Compaq Presario F700 laptop with an AMD Turion 64 X2 processor
