We have a T61, but not the same type as the OP has, but it's also making fan noise. Ours is a 6463-4YU. Advice needed! The situation:
It's a second-hand machine purchased a few weeks ago from a reputable reseller. My husband has begun set-up but has not yet installed routine software like word processors. He's had it running for about 45 minutes and the fan is loud. It sounds like static coming from a speaker when a radio is between stations, but loud. He hasn't yet been able to find out what the fan does when one is using something like a word processor or image processor. (Life has been happening in a big way.)
He knew the T61s had some fan issues and was assuming that a fan replacement would be an option. However, reading further about fan noises in T61s, we see they come from various causes, and a fan replacement is the right solution in some cases, but a firmware change or some such is the right solution in other cases.
So here's the question. We are trying to figure out whether to keep this laptop or to return it while we still have time.
1. Does the "loud static" fan noise alone already tell us it needs a new fan?
2. Do we need more info about fan behavior before we can know if the fan needs to be replaced, and if so, what's the minimum software installation and use test we can run to find out what we need to know? (We're hoping to avoid spending hours installing everything before we even start further testing.)
3. Does a refurbisher's warranty cover the "loud static" fan noise problem, or any fan noise problems?
4. Does our laptop sound like a "return this while you still have time" (5 days), or a "test further and then decide," or a "don't worry, your investment is safe, because if you do have a fan issue your warranty will cover it anyway," or a "keep the laptop and replace the fan yourself" situation?
5. If we do need a new fan, is the advice the same as for the other poster--Toshiba 42W2460 or Furukawa 44C0825?
Advice much appreciated! Thank you very much.
