My ze2308wm was picked up last November as a black friday special. And has worked great, but of course with a sempron 2800+ processor wasn't too fast with encoding or editing. Checked a while to see if Turion would be compatible since same socket (754). Read through CHARVEY 's post on upgrading his compaq v2000z. Decided to take the plunge, bought a new turion ml-37 off of ebay. Followed the manual from HP's website on disassembling the computer.
I'm happy to say that it went smoothly. The new ml-37 was recognized immediately. When running at 800mhz by powernow it does not go above 50c and at 2.0 it doesn't go above 60c. (This is with the thermal pad that came with the computer.)
NOTE-the hp manual contains minor errors in disassembly but if patient it is no problem.
with the sempron I never used the powernow feature since was already a slower cpu, but I am now using it with the turion and have noticed an increase in battery life. this would probably be due to the powernow and not the processor change
also upgraded memory to 1.5 gig (a 1gig stick and a 512 stick). 128mb is shared for ati graphics card.
$398 for laptop $130 for memory (1gig & 512mb) $100 for cpu new from ebay
hmm, next upgrade hdd
any suggestions for a good option on hard drive upgrade
if you want a hdd witht most storage i would get the seagate 160gb but it is only 5400 rpm. if you want maximum performance get a 7200 rpm, both hitachi and seagate offer 7200rpm models up to 100gb. i have the hitach 7k100 and it made a noticeable difference in windows boot time and in application load times.
Turion ML-37 is a power hog, so much that speed is limited to 80% while on battery. You need to be on AC power to run at full 2.0GHz.
On AC power, power usage at the plug in was 55W at full load. Sempron 2800+ was using 38W. All for 25% gain in performance.
Measured performance in Sandra and Super_Pi was almost exactly 25%.
25% gain in speed, 45% gain in power use.
Big error in the manual:
The keyboard cover screw is specified as PM2.0x8.0. Sure... I didn't keep track of screws when I took them off and I used the manual and caliper when I needed to know what goes where. 2.0 x 8.0 screws for keyboard cover = punch through.
