Precision M4400 Owner's Lounge *Part 2*

A lot of people have purchased copper shims from e-bay to replace those thermal pads.

 

Any idea what shim thickness is appropriate? Would the original thermal pads' thickness serve as a good base or do things like pad compression need to be factored in?

 

I'm moving on from my M4400. I'm wondering what the going price is so I know what to sell it for?

Mine is the QX9300, with the FX1700M, WUXGA (CCFL vs LED), Backlit Keyboard, WWAN and WLAN have both been upgraded to later models of those cards, and I didn't like the LCD back of the Precision, so I replaced it with the smooth back of the Latitude (probably still have the Precision back laying around). It also has the fingerprint reader, and right now, and Intel 80GB 320 SSD. The 9 cell battery is shot, but I do have the slice battery.

Thoughts on what my selling price should be?

As you haven't had any educated replies, I'd suggest you do a search for completed items on eBay (whatever country you are in) and check out those in the resulting list with green prices - see how their specs compare with yours and make adjustments accordingly.

This is what I'm getting now, with no other search criteria besides "Completed listings":

Here's my M4400 as it stands:

1920x1200
FX1700m
3Ghz T9900
50GB and 64GB SSDs
4GB RAM
Windows 7

It has the 9 cell battery from when I had an E6500 (And even that was used when I got it.) and with the GPU at pstate10 and the CPU undervolted/underclocked I get roughly 3 hours max. (Not gaming.) I was thinking of buying an aftermarket 12 cell off eBay and possibly a battery slice. How much battery life would I gain with this slice?

What is the wear level on your 9-Cell? Assuming you're getting 3 hours on say, 50% wear, you could see 3x, maybe 4x runtime from two new batteries.

 

According to HWMonitor it's at 18% wear. I know the person who used the laptop with this battery in it rarely ran it without it plugged in. (Work laptop. Got it for free.) I don't use it on the battery very often but when I do I tend to run it down until it dies or is near dead.

 

Then you'll probably be getting more like 2x to 2.5x runtime.

 

Yeah, so that 12 cell has barely any more capacity than my current 9 cell did when it was new. (Held about 8700 mWh new and currently holds about 7000.)

Still might get the slice.

 

I broke out my M440 to handle some backup work because I missed using it.

I forgot what a nice machine this is and how comfortable the keyboard is to type on. I still have my list of upgrades that I want to do and will start setting aside my pennies.
