Default R40 Cooling Question

Ahoy there!

I think my computer and the month of January must not like each other very much - we're on year three, and they're battling to the death again. So far, January is winning.

I've been experiencing a lot of short-term lockups and freezes as of late (the computer will lock up for 10-30 seconds, the fan will kick in, the computer will resume for a minute or two, the fan stops, wash, rinse, repeat). I'm pretty sure that my computer is overheating, and that the fan(s) are in dire need of replacement. Anyone know what kind of fans the R40's take, or if they're even replaceable for that matter? I haven't bothered to get *that* thorough when I've cracked this baby open in the past, and I'd rather get an answer rather than dig around the intestines of this puppy first.

If there's no way to replace the fan, is there a fan controller located anywhere in the system settings that I can access? Any recommendations on other cooling solutions?

EDIT: So... I've done some research since this post, and I notice that the fan assembly kits are indeed available. Are they available at Drew, or would we have to send the computer out for repair? If that's the case, I don't mind ordering the assembly kit and doing it myself. But... y'know... if it'll save me $35-40, then that sounds great.

The only fan in the Thinkpad R40 is replacable but IBM/Lenovo does not consider it a user replaceable part. What this means is that they want only certified technicians to replace the fan inside these computers. The fan is connected to the heatsink on the CPU and when this replaced you need to replace the thermal pad on the heatsink. I don't know where you looked up the fan, but installing the wrong part or a non-IBM part may result in more damage to the computer than actually fixing the problem. Also when installing the fan and the heatsink there is a chance of actually damaging the CPU itself.

The problem may also be something other than the fan on the computer or only a symptom of another problem. It could be that the computer's thermal sensor on the mainboard or CPU is malfunctioning and sending bad readings to the fan causing the strange behavior. You said the fan has started up and blows air out, but stops and starts. Have you checked the temperature of the system using a monitoring utility at all? It is possible that this could be a mainboard replacement and not the fan. Usually the mainboard controls the fan's speed. Another possibility that can cause the behavior you are describing is a bad hard drive. A failing hard drive can sound like a fan due to the moving platters inside the drive. When the hard drive hits a bad spot it can cause the delays you see in windows and spin down and up. If the fan is indeed broken, I can order the fan and replace it under warranty for you if you bring down to the helpdesk. If it is determined to be some other part in the computer malfunctioning, I can order that part from IBM/Lenovo as well. This barring any situation where the part cannot be replaced under the standard warranty.

Please bear in mind that repairs of the machine are done on site with the exception of repairs that fall under the Accidental Damage warranty. Those machines are sent to IBM/Lenovo which may take longer due the shipping time to and back from their facility. Accidental Damage repairs are sent to IBM/Lenovo for repair. The delays that may occur for repairs on site are for the shipping time and when IBM/Lenovo parts are backordered at their facility.

I have not used any temperature monitoring software as of yet. Any recommendations?

If it's the hard drive, I'd be a little upset - I'm on number four right now. I'm not sure if this is the case or not. I would bring the computer down and show you the problem, but it's a little finicky... it'll either be flawless, or mess up nonstop.

I suppose I could just replace the hard drive (a fifth time) if that's the case. For now I'll check out the monitoring software, and if it gets any worse I'll bring it on down.

Also, the fan assembly kit I looked up matches the part number of the fan in the R40 (which I believe is 46P3099). I've done plenty with hardware, but I'd still rather have someone who replaces these things for a living if it comes down to it.

EDIT (to avoid being a silly double-poster): Did a little more experimenting. It's... looking like it's probably the hard drive. But the fan thing is still sort of baffling me, as that's still going on. Basically, any minimal amount of pressure on the laptop's case over where the hard drive is located causes a lockup. So... yeah. Think I'm gonna' need a new hard drive.

Hi Justin,

I looked at your call history with the help desk and we do not have a record of any hardware components needing replacement. Your computer has been re-imaged several times, which means the software was reinstalled, but there have not been any hard drive replacements.

Please do bring your computer to the help desk so we can run some tests. We have an IBM-certified repair technician on campus if parts do need to be replaced.

The desk attendants can also tell you how to fill out a loaner application if the computer needs to stay with us.

Hope this helps!

Hey Betsy.

I have replaced the hard drive myself through IBM over winter break, which I quickly learned did me no good, since I had no system discs with which to reinstall windows.

I have had the computer re-imaged a number of times as well. I'll bring it down soonish.

When you do visit, please let us know the case number that IBM issued to you so that we can enter it into our tracking system. IBM/Lenovo honors the contract we have and will issue a replacement laptop if yours needs three or more major hardware replacements within a 6-month period. This is not part of the general warranty, however, and must be initiated through CNS.

We'll see you soon.
