Edge E535 fan speeds erratic

[BlueEdge]

Hi all:

I'm new to the forum, and part of the reason I'm here is that I just got a new (well, refurbished) E535 through Lenovo outlet. It's for general use, nothing demanding, so I'm pretty confident that it was a good choice.

All is going well after about a week of ownership, but there is one moderately annoying thing going on: After about two or three minutes of operation with nothing more than Firefox operating the fan will rev up to its highest speed -- and then slow down, and then speed up, and slow down....over and over and over and over. It does this whether its plugged in or on battery.

Not really a big deal, but I'm wondering if this unit is having problems cooling itself and what the long term outlook for it might be. Has anyone else experienced this, either with this model or another Thinkpad? (I'm new to laptops, so I'm not familiar with the power management and fan operations).

Thanks in advance.

(Almost forgot, the specifics - E535 with AMD Vision A4300, 4GB RAM, 320 GB 7200RPM HD, AMD Radeon graphics, Windows 7 Home Premium).

have you looked for BIOS updates on lenovo's site?

In fact, I did check there and there appears to have been an update that says that it addresses fan issues, but without anything more specific than that. So I'm wondering if it would be wise to just go ahead and do that update without knowing anything more than that? :-0

Thanks for the reply.

it is more than rare for it to damage anything
