Hi all, hopefully someone here can help me out, I've got a mid 2010 MBP with some GPU and battery issues and I'm trying to figure out what to try/replace next.


Here's the mac:

mid 2010 15" with 2.8 i7 running 10.6.8 snow leo
8gb ram (memtest ran, confirmed no issues with either stick as well)
500gb HDD
1680x1050 screen
330gt 512mb version GPU with intel hd GPU switching


My problems: (as best I can explain...)
#1 the battery
Firstly, the battery. No matter what, my battery is throwing up the condition: "Replace Now" status to the system and will not charge at all. Looking at the system info I get this:

Charging: No


^You can see, the battery is being read as having on 242 cycles on it, but doesn't seem charge under any circumstances. I read somewhere that an indicator light would change color on the MBP when the battery was charging? Maybe on my magsafe? (forgive my stupidity - longtime UNIX, macpro, and hackintosh guy here - first time MBP owner :!: ) As of now I only have the magsafe connector lighting up a solid green.

I picked up a new DC/magsafe in board/connector from a friend earlier today and replaced this port on the side of the MBP. Unfortunately no change and I still just get the solid green light - so I think this is working correctly as is my 85w power adapter. I've tried SMC reset as well but I'm not even sure if it worked. Again, I read somewhere that the light on my magsafe should've turned red but Control+option+shift+power didn't seem to do anything for me.

Any thoughts/suggestions on these battery issues?



#2 The GPU

Also, a totally separate problem, my MBP seems to crash whenever switching from the intel GPU to the Nvidia graphics. Everything basic presents no problem, web browsing, word, simple desktop tasks. But running anything GPU intensive seems to crash my system, although I can't tell if it's actually becoming totally unresponsive or not. Once the Nvidia GPU should be running, I just end up with a black screen...

Gut instinct tells me this means bad GPU, bad driver, chip overheating and unsoldering from the main logic board, or vram failure. I'm just not sure where to start or what the next step should be for further troubleshooting to find the cause of the problem. I think SMC reset could also be useful for this but again, I don't know if SMC reset is working correctly or not.

Part of me wants to just update to mountain lion and see if there is a driver fix but that seems like a long-shot solution. Also my 10.6.8 is fully updated as is. I have also already cleaned the system of dust and went through everything, redoing the thermal compound and pads. The compound itself I cleaned up with AS Thermal remover/purifier. I also replaced that cheap/badly applied stock compound with Tuniq tx4, before reattaching and evenly tightening the heatsinks. In any case, I think I can now rule out the overheating as well.

Any thoughts here, what do you think I should try next with the GPU issue?

It might be the battery itself. Even though it only has 242 cycles, it might still be the battery.

Yes, if the battery is charging, then the light on the MagSafe connector should change to an orangish color until it is fully charged. If it is staying green, then it further suggests that there is some problem with the battery and/or power system.

It kind of sounds like you took stuff apart (the talk of new thermal compound, etc). If so, it is possible that you damaged some component related to the integrated graphics card.

Overall, the "easy" suggestion would be to take it to an Apple Store if there is one near you. They might be able to tell you if there is a problem with the battery at least, but also if there is a problem with the graphics system. Obviously, it likely will not be covered by warranty, unless there was an Apple Care Extended Warranty with it...and even then if you did redo the thermal compound, that might void the warranty. But, I believe you can still pay to them test the machine for less than $100.

If you don't want to go that route, then you are really outside of my wheel house. The best that I could offer is to try a new battery, but if it is not the battery, then that could be a waste of money.
