Over the weekend the cooling fan on my MBP became very noisy. Sounds like a bearing noise or something. It's a rattle like noise versus a squeal or hum. First appointment I can get to take it in is Thursday. Question 1 is should I limit usage as much as possible until then and keep it powered off as much as possible? The fan is still running so air is moving. It may just be a nuisance. Question 2 if anyone has had to have this repaired is it something they can do for me while I wait? Thursday is Month End at work and I really need THIS computer because it's configured to VPN through the secure portal at head office. As Murphy would have it, the timing is not good.
