kernel panics on MacBook Pro (Early 2008), possibly SMC related

macbook-pro kernel-panic power-management

I am a proud owner of a MacBook Pro from Early 2008 (MacBookPro4,1), which is (apart from the problems) still running strong. Unfortunately I have been getting kernel panics for a while now. I am not 100% sure but I think it started after I let the battery drain completely one night with the MacBook being in Standby. The next morning it wouldn't turn on and I did not just have to reset the SMC but bypass it. After I started the MacBook that way I could restart normally. This was about two months ago and I think since then I get the kernel panics every now and then.

More Information:

  • MacBook Pro (Early 2008)
  • 6Gb RAM
  • Mac OS X 10.11.6
  • 2,4 Ghz Intel Core 2 Duo
  • NVIDIA GeForce 8600M GT 128MB

I also experienced the kernel panics in Safe Mode and during start-up and while I was trying to reinstall macOS. Right now I have the MacBook running while bypassing the SMC and I haven't had a panic yet.

The kernel panics appear randomly. I have the feeling that it happens more often when watching videos on youtube, but I can't say for sure. The battery is pretty much wasted and only holds for about 30 minutes. The MacBook usually turns off at 6-10%.

Then there is another problem, which might be related: When I use the MacBook on battery and with the internal keyboard and trackpad it sometimes hangs for a few seconds in which it first doesn't take any input, and then takes the input but doesn't show it until a short moment later. This has been a problem for a long time now.

Also I have recently noticed that I have been using the MacBook with a 60W power supply unit instead of the normal 85W unit. The original one was broken and I just grabbed another one that was laying around, not knowing that Apple MacBooks actually had different power supply units.

The Apple Hardware Test doesn't find any problems.

One more thing: My login screen shows a weird background. Kind of like the background is made for a screen with a lower resolution. This background is shown on the internal screen and on an external screen.

weird login screen

A look into the kernel panic reports shows that most of the are due to page faults with error code 0 (meaning that a page was requested, that doesn't exist).

I would put all the reports up, but that might be too much in this question? Here are the two last recent ones.

UPDATE 1 (24.04.17)

The freezing depends on the use of the internal keyboard and trackpad only. It happens independent on the power source. With less RAM now, it eventuelly freezes and doesn't come back. It still reacts to external devices and the power button works as well.

The MacBook doesn't boot with the battery removed. I have done several SMC resets. Without the battery I can only boot by bypassing the SMC.

I have not had a kernel panic since I removed one RAM module, but of course this could just be, because it just hasn't happened yet.


Solution 1:

Troubleshooting is a process of elimination so we're going to need to have some patience. :)

Usually this site is geared to answering one question per question, but you've got a number of issues which may or may not be related, so we'll see how we go.

Before proceeding let's ensure your MBP is running isolated from other hardware (no external displays, hard drives, etc).

Keyboard/trackpad

Let's start with your keyboard/trackpad issues. I suspect this may be due to your battery, so we need to test for that. Since you can't boot without your battery, I'd try the following:

  1. Boot your Mac as per normal (with the battery inserted and your Mac connected to AC power)
  2. Now put your Mac to sleep via the Apple menu
  3. Once it's in sleep mode, close the lid
  4. Remove the battery
  5. Open the lid
  6. Assuming your Mac is still on and you can use it, test your keyboard and trackpad

Now, if your keyboard and/or trackpad are fine then you know their issue(s) are related to the battery. If this is the case, it's a simple fix - you need to replace your battery (although you may not want to do that until you know what's causing your other issues).

Kernel panics

For now, if you can still use the MBP after Step 6 above, use your Mac (watch videos etc) to see if you can generate a kernel panic.

Let me know either way how you go.
