Question

Laptop turns on and then off after a few secs

by notg / February 28, 2012 9:41 AM PST

Hi everyone,
I have searched the web for answers to no avail that is why I am posting here.
I have an iBUYPOWER CRZ-92 her which has been used for about 3-4 years. Recently when turned on, the fans start working for a couple of seconds and then turn off, the power button is still lit and the hard drive light flashes few times as well, but at the end nothing happens; the screen remains blank (does not even show that something is about to be shown) and if I press the power button once, the laptop turns off completely (I don't even have to hold the button for 4-6 secs to turn it off).
I tried opening the back of the laptop, per recommendations that I found online, to take a look at the power, fan, etc. but I could not open it completely. Is there any way that I can fix the issue without having to open the laptop? If not then how can I erase the hard drive content to put it up for sale?

I appreciate any and all help.

Ouch. Google 8600M DEFECTIVE or RECALL to learn what happened.

All the boards I encountered are replaced when I see this one.

I didn't know about this problem!!! I bought the laptop about 4 yrs ago, don't think I can get any reimbursement for this issue now! Thanks for the info though. How can this be resolved? by replacing the graphics card only?

Most laptops do not have a graphics card
by R. Proffitt Forum moderator / February 28, 2012 12:33 PM PST

But if yours do, consider changing that one. But for most laptops it's the end because most folk having learned about the issue and faced with the bill will just chuck it. I think the other parts are worth a little on ebay.

Won't Boot Up

I have the HP Pavillion with essentially the same problem. After some tests it too was the mother board. My son used a counter top oven and heated the board to 400 degrees F for just a few minutes. He covered the chip to prevent it from getting too hot. Anyway the solder reflowed and the laptop is working. I doubt if we do this again. It's way too much trouble. I won't be surprised if it gets too hot again and looses continuity. Thus, we call it a hand gun target.
