I have a Dell M4800 laptop with weird hardware stability issues. Occasionally it will hard freeze, turn on the fans to maximum, and require a hard reboot. Other times, it will fail to suspend properly. Or rather, it suspends, but then immediately wakes itself up again. This has resulted in it waking up in storage, where it tries to cook itself from lack of airflow.
Does anyone have an idea of where to begin troubleshooting? I know this is beyond economical repair, but I can't find a suitable replacement anywhere. I'm not giving up my three touchpad buttons and non-chiclet keyboard without a fight.
