I found a guide online and was able to take my laptop apart, but it didn't include anything about the odd screww (#4) - under the battery near the IR sensor. It is different from the others a star shape with a pin in the center. I can't seem to get it out and didnt know if there was something special or a tool that will remove it without breaking the plastic case? Thanks in advance.

You probably need to replace the cooling fan, but you can try cleaning it out first. Get a can of compressed air or use an air compressor to spray pressurized air into the vent to spray dust out. If this doesn't work, you probably need to replace the fan. I actually found a guide for opening up the Qosmio G25 and replacing or cleaning the cooling fan. Check it out:
Hi! I'm taramarsh to assist you today with this issue! So...
Replacing or cleaning cooling fans Here are the steps: 1. Place the notebook upside down and remove the battery.
2. Remove hard drive covers and the memory cover. 3. Remove both memory modules. (The Qosmio G25 model has two hard drives. Hard drive #1 in located closer to the battery).
4. Remove one screw while you will secure the hard drive and make it to slide out. Because the two hard drives are looking similar I suggest you to mark each one apart for a later identification. In case you will not do that and will mix the HDDs you risk to not be able to boot back into your operating system...! 5. Remove the rest of the screws on the bottom of the notebook and disconnect that cable marked with a tiny red arrow. 6. Disconnect the two cables existing on the left side of the modem card. The modem is secured to the motherboard by two screws. Remove these screws.
7. Lift up the modem from the motherboard (the last modem connector is located under).
8. Disconnect the cable from the modem (top arrow). 9. Turn the laptop into the normal working position (keyboard up).
10. Using a screwdriver or a flathead tool lift up the keyboard plastic upper part.
Remove it from the laptop. 11. Now you have to be able to see three screws situated on the upper part of the keyboard. Unscrew them all. 12.Remove the keyboard and flip it.
13. Are also two screws attaching the keyboard connector cover. Remove that cover. 14. Move gently the keyboard to be able to see and identify the connector on the motherboard. 15. Remove the cable and remove the keyboard.
16. Now you have to be able to see SIX screws: two attaching the video connector cover and the rest of four securing the top cover. Remove all starting on the left side with the two video connector cable. 17. On the video connector side unplug the cable that has a WHITE CONNECTOR. 18. Flip to close the display. 19. Turn the notebook upside down as it was from the beginning of this operation. 20. Lift up the bottom part of the notebook case and remove
it. Pay attention to the latches on the sides. 21. Opening the cover will let you see the WLAN card, the optical drive, the TV tuner and the two fans.
Following factors could be causing this problem and solution as well:
1) Cable Cut: check is to see if the cable between the screen and laptop is pinched or cut. Every laptop has this wire that runs through one of the hinges
2) If this problem temporary i mean for some seconds then it could be a short signal cut problem to screen which causes screen distortion
3) Connect an external monitor and restart the laptop. If you see the same
strip on the external video, then that is the motherboard or the video
card problem in case you have a video card on your laptop apart from integrated graphics chip
Hi Paul have a g25-av513. First disconnect and remove both hard drives and the battery. In the battery compartment there is a small screw you need to remove and in the hard drive 2 bay there are 2 f8 screws that need to be removed as well. In all there should be 17 screws that need to be removed before you can pop the back cover off. When removing pay close attention to the connectors attached to the underside of the back cover. be careful not to pull to hard or you may tear the connectors which are very thin wires. First you have to remove all the screws on the underside of the laptop. The screws are marked f8's and f16's the longer ones are the f16's of course. I have taken mine apart several times already due to a boot up shut down issue which I believe is related to the modem board underneath hard drive 2. It seems that when ever I disconnect and reconnect this board my power shut down issue disappears. If it happens again I'm going to remove i all together and see if that takes care of my problem.
