dv1000 vs l2000 - will the first be cooler?

I have a L2000, and as much as I like what it supports, the whole machine really runs warm for me, and I just don't find it comfortable. Would I be happier with the dv1000, which has the Pentium chip? As much as I wanted an ATI vid solution and non intel stuff, I don't want the heat, and am thinking of sending it back...


Any advice is appreciated...

What are you using the computer for that is generating the heat?

Have you tried a different harddrive?

How much RAM do you have ?

 

I have gotten a toshiba hard drive to replace that samsung drive they originally sent me -

1.8 Ghz

Has some luck with CrystalCPUID, but certain games (roller coaster tycoon 3) cause cpuid's effect to be cancelled, and not stay undervolted...
Other apps used: Photoshop

I'm running with 1 GB of RAM...

The heat is from the left wrist, where the hard drive is, and then can be felt (by me) though the keyboard after a while of use - Granted, I live in the cold up north and dislike the heat, so I may be a bit oversensitive - still - this is my last computer for the next 5 years, and I need to be happy with it in the end...

 

I have felt it. Its a powerfull system for its size and if you use it alot it does get warm. It doesnt bother me but if you dont like it you might try the dv1000, I havent heard or read of anyone remarking about heat as a problem.

 

As of right now, Pentium M notebooks are still cooler than Turion ML notebooks. But once Turion MT becomes widespread, I think AMD will finally have a chance of catching up with Intel.

 

Are the MT's just on the horizon, or are we talking 6 - 12 months away?

 

The Turion MT's are showing up in various mail order shops (try Froogle) and small notebook builders like xmeld.com (MSI 12" and 15.4" notebooks). HP tends to only offer the lowest-grade (cheapest) CPUs though. If you're feeling really adventurous you can swap in a MT on your own and it will very likely work. I'd wait for HP to post the service guide for these notebooks first though.

Seagate and Hitachi make the best notebook HDs. Almost everything else runs hotter to varying degrees. I really don't think the CPU is the issue here, it's HP choosing to put the hotter-running HDs in a thin-and-light chassis that they have no business being in. They should be reserved for the DTR-class machines, if they have to use them at all.

MobileMeter says the Hitachi 7200RPM HD in my zv5000z is at 44C now. I swapped in a Mobile-class Athlon 64 (62W max, vs. 35W max for a Turion ML and 25W for a MT) so the fan only kicks in when the CPU hits 55C, which isn't all that often when the machine is relatively idle. When I had a DTR-class CPU and the fan ran all the time the drive stayed even cooler. There's no excuse for slower HDs to break 50C unless they're under serious load.

 

Hmm, I keep hearing about some people staying the heck away from a DV1000 because the demo model they saw in a store was burning hot. All of the demo ones I've seen had very little to no heat though.

 

hmmm...wouldn't swapping in my own chip invalidate my extended warranty?
So, you are saying that the problem is not the chip heating up the whole thing, but the Hard drive heating up the whole thing?
I like this laptop, except for the heat, so maybe if I buy a better hard drive that runs cooler....I just shouldn't have to - but I shouldn't have to go through this whole shopping trip all over again - it took long enough to decide on this one!

 

Fujitsu is the only manufacturer in the US that is offering them in notebooks right now but we should see others with MT by the end of this year.

 

All the components are contributing to the heat buildup but imo, the heat shouldn't create that big of a problem. And yes, putting in your own chip will void the warranty.

 

So is it for sure just plug and play? And do you know when the service guide might come out for these laptops? Thanks

 

Swapping in your own chip would most definitely void your warranty, extended or otherwise. But yes, I don't think the CPU is the problem. In low-power mode (800MHz at 0.95V on Athlon 64 notebook chips, I'm not sure about the Turion) a Turion ML and MT should burn the same minute amount of power, not nearly enough to cause the notebook to get exceptionally hot. A hot-running HD could do the trick though and all reports indicate the hot point is the left palmrest where the HD is located. As rahulnirmal's previous message indicated some dv1000's are reported to run hot in the same manner, suggesting they are allocated the hot HDs less frequently than the L2000's but behave the same way when they get them, which is what I'd expect given the nearly identical chassis.

If you really want a Turion MT, see here:
http://www.xmeld.com/html/msi1029.html (15.4" widescreen X700 video)
http://www.xmeld.com/html/msi1013.html (12" widescreen)

Some of the other small vendors have MT's too but xmeld appears to be one of the more competent ones. They use Seagate HDs. Once MT production is high enough I'd expect the larger vendors to start using them too. I don't know when that will be, could be a while, absolute worst case when the 65nm fab ramps up early next year.

 

It was plug-and-play when I swapped CPUs in my zv5000z and, barring a BIOS issue, it is that way with pretty much any modern motherboard. I have no idea when they'll post the service guide. I do expect that HP will have made CPU swaps much more difficult than they did with the zv5000z series. I don't think a ML to MT swap is worthwhile at this time.

 

L2000 "heat", which isn't bad, is caused by two things:

-HD in thin plastics case. Compaq V2000 exactly the same issue. The reason the DV's exhibit this less is thicker plastic (and more weight).

-CPU. AMD's ML runs hotter, and fan kicks on. This is as designed.

Quite honestly, these issues to me are nothing...I'd rather have the much better ATI chipset (intel graphics blow), and the 64 bit cpu for next year's Vista release..

I'm loving mine...the 12 cell battery lasts plenty long.
And the tiny AC adapter is another bonus.

In the end, I couldn't beat the price/performance.

 

Well put Mikec,

If you feel around where the harddrive is in most laptops it will feel warmer.

The AMD does run hotter but its not that much hotter and it isnt what most people are feeling although it is what causes the fan to turn on.

I spent hours working on the L2000 and its always the harddrive that heats up the left palm. As for the fan I didnt notice it but then Im a little hard of hearing.

 

Though i'm waiting for a few more responses in the hardware thread, I think i'm keeping the L2000 but buying the Hitachi Travelstar 60GB 5400 - According to one user on here, s/he measured temps no higher than 35 - 40 with that drive...I think a 15 degree cel. difference is worth $100 and no headache of returning this computer...Plus, I can probably ebay the toshiba hard drive I have now...

 

I've had my l2000 for a week and I'm pretty sure I'm going to return it or possibly replace the HD. I have the 100gb Fujitsu and the left palm is far too warm. Just sitting here searching the forum MobileMeter is reading 53.0 C.

Any 100 GB drives that run cooler?

 

My L2000 emits an ecessively high magnetic field when in "Desk" mode. The field drops significantly by selecting any other power mode. Not sure why it jumps so high but most likely it's also consuming more energy there. Any idea what the desk mode is doing to cause such a high field? I don't see much difference in performance, but I'm not a gamer.

 

well i do have a dv1000 and my lappy has no heat issues at all
so you can try the 1000 i dont know why anyone would say a dv1000 has heat issues i have had mine on all day today since 10 am and its 10:27 pm now so been running more than 12 hours and only mildly warm on bottom in one spot and i have been playing games for hours so i have been useing it not just setting idle

 

As much as I don't like Intel (their crappy GMA),
I decided to go with dv1000 after keeping L2000
for 3 weeks. In those 3 weeks, I tried all possible
suggestions in this forum:

1) 12 cell battery (orig was 6).
2) Undervolt using RMClock util.
3) Swap samsung HD with a) Seagate b) Hitachi

#2 above helps if you keep the management setting
to minimal.

For me, heat and fan kicking in was just too annoying.
I'm more sensitive to noise than most other folks.
It's a shame as I really liked L2000 with 64 bit processor
and ati card.

DV1000 is nice too. It doesn't get hot on the left.
Interestingly, my dv1000 unit came with same Samsunt
60GB hard drive! Talk about cost cutting measures...

No doubt, the L2000 is as much an oven as it is a laptop. But it makes for a half-decent desktop replacement. The Extreme Graphics 2 in the dv1000 is a major obstacle. But it's fine for general purpose use.

 

I just don't get this. Even Tom's Hardware has found that the Turion beats the Pentium-M in 2 of the 3 battery benchmarks they tried:
http://www.tomshardware.com/mobile/20050906/turion_64-12.html
But they used a MSI Turion notebook, not HP. The HP L2000 and V2000z series notebooks I checked out at CompUSA and Best Buy seemed cool-running to me. I can't make any sense of what could be heating up the HP Turion notebooks that much.

 

I really wanted a 64 bit but I couldnt live with the fan so I also chose the dv1000.

 

Anyone else find it strange that the fan is on the bottom of the L2000? Fans are usually on the back side.

 

Not really that strange, newer laptops have the fan in the bottom, backside fans make the laptop too thick.
