I learned that with a simple BIOS flash, the original 1.7 ghz pentium M “Banias” CPU (130nm process, 1mb L2 cache) that came standard with the T41p can be upgraded to a 2.0 GHz Pentium M 755 “Dothan” CPU (90nm process, 2mb L2 cache) which was available in the later T42 models.
For this upgrade you’ll need: 1. IBM ThinkPad T41p hardware and maintenance guide. The maintenance guide will help you to remove the keyboard and palm rest and get down to the CPU socket. 2. Small Philips screwdriver. 3. Thermal compound. Before you mount the heatsink back on the CPU, you must apply new thermal compound on the top of the CPU. You may consider Arctic Silver thermal compound. This stuff will keep your CPU cool and stable. 4. A can of compressed air. That’s would be a great idea to blow off dust from the cooling modules while you are replacing the CPU. Removing dust from the heat sink will help to prevent laptop overheating.
Before I go any further, you should know that this upgrade is not for the novice or fumble-fingered. There are any number of ways you can completely destroy your computer during an upgrade of this type. From losing tiny screws to shorting out the motherboard with static electricity or dropping a screwdriver into the open computer, this is not a project for someone who is not already fairly competent wielding a screwdriver and performing computer upgrades.

You will need a bios update to accept anything bigger then 40gb, just goggle and you will find it.

I have a t41 with a 40 gig hd and want to upgrade the hard drive. I purchased a WD160 (WD1600BEVE) and cloned the newly installed XP Pro srvc pk 2 using WD Data Lifeguard Tools. The cloned drive competed the cloning process successfully, I guess. Now when I install the new hard drive and turn it on it proceeds to start up and then I get a blank screen with the cursor sitting at the top of the blank screen blinking. I flashed the bios to vrsn 3.23 and still the t41 refuses to recognize the new drive. What am I during wrong? Is there certain models that work best? Also what adapter (brand and model nbr) would be needed to convert to sata drives. Help?

Am running T41 Upgraded to 2 gg Ram 120g drive 1.8ghz Dothan .. went through 1,7ghz on the way lol, got DVD rewriter ebay (from Latvia) picked up a hong kong bay hard drive cradle … suffers from the heat related (dry joint) vid problem though .. this only manifests on cue club the only addictive game i play, otherwise i love it … win XP Pro, P/Shop cs .. plenty of power.
Anyone addressed the problem of vid via reflow services or such like??

I want to upgrade my cpu. Is there a maximum L2 cache a MOBO will support or doesn’t it matter how high I go on L2 cache?

Hi Laptop Tech, I now own a T41, type 2373 which is running a 1.6ghz cpu at present, was wondering about doing CPU and Hard drive upgrades and was hoping you can tell me what the maximum cpu speed will be and max hard drive size would be. A cpu model number would be great.
Many thanks in advanced,
Chris.
