HP Pavillion dm1, any opinions? reviews?

BatteryBar says 5:30 with Wifi on, dimmed screen, surfing.

BatteryBar is quite critical and predicts lower lifetime than Windows. For some mysterious reason Windows can not predict battery life on my DM1.

After installing a Intel G2 SSD BatteryBar says about 5:20.

 

whats the real life time? I don't like these software like battery bar. what are you getting more or less in your opinion?

I would have expected at least 1 to 2 hours more than the mini 311. The hp mini 311 can do around 5h30 surfing with Xp and thats with an ion chipset which consumes more power.

 

Have you worked with Batterybar? I think it's pretty accurate. But I haven't really tried to measure it accurately.

ION consumes more, but the SU2300 doesn't have speedstep. It's always on 1.2GHz.

For gamers ION is interesting. For non gamers Intel 4500 does everything just as well. It plays planet Earth's Bird Scene 42Mbit with 20% CPU.

 

hmmm weird because intel says it supports speepstep : http://ark.intel.com/Product.aspx?id=42779

I've seen some tests , forgot where now that showed atom+ion consumes more than culv+ intel chipset. I might be wrong.

 

Well that is weird. I just checked with CPU Z and RMClock and it's always on 1.2GHz. That's what the name Celeron implies aswel.

If the DM1 is available with SU4100 it will get better battery life.

Edit: I've asked other SU2300 owners if theirs is always on 1.2GHz

I've seen online that the dm1 is available with su4100 in the UK.

I wonder if HP will bring this to NA. Why are they taking so long!

 

The real life time is about 4:20 (wifi on, surf, 80% brightness),
5:30 (wifi off, typing, 80% brightness),
2-3 hours (game, video)
Asus say their EEEPC 901 has 8 hours battery but the truth is 6
HP says their DM1 can do around 9 hours, but only 4:30, i'm so dissapointed.

Here a link about SU2300 "speed step" : http://scottiestech.info/2009/12/31/the-intel-su2300-does-not-have-speedstep-as-you-know-it/

 

It seems like I'm now getting more than 6 hours out of my DM1 with SU2300 by pressing F4 in CrystalCPUID.

I just got the DM1, am pretty happy except one thing:

The fan seems to run at all times - even on idle desktop and on battery.

I found out on this website, that the SU2300 actually doesnt have speedstep, dispite all the claims from intel.

Anyone got the same observation, that the fan is always running? Even on battery doing nothing? Any way to get around this? It's the one thing that makes a otherwise perfect machine a bit disappointing - else the thing is perfect value for money!

 

Well there is a setting in the bios for the fan, you might want to try it. My fan runs at all times but I can barely hear it.

To force a lower clock rate look at the post just above yours.

For improving the screen quality you can lower the gamma in the Intel graphics settings.

 

I bought one with su2300, is not as quiet as expected, especially when used in a quiet room, even when turned off the fan always on option in the bios. This is true even in tasks such as browsing pages with little flash, some times its difficult to the fan to stop.

Besides this issue I have two situations:

1 - The battery icon doesn't gives expected time in HH: MM only %, which passes from 100 to 95 or 94 at once in 10 minutes, strange.

2 - When the windows starts or comes out of sleep mode, the right speaker makes a noise.

 

Somehow HP has disabled the option to show remaining battery in hours. This was the same on my DM1 and my current DM3.

 

And changing from 100% to 95%, its normal.

 

I've never seen that.

 

Interesting thread, I'm stuck between getting an Acer 1810 or a DM1 (su1400)... any opinions? I basically need something as light and portable as possible and these two seem the best, I'll be using it for work mainly (Word, Excel, Outlook) and probably watching a few videos, MSN, the usual. Nothing strenuous. I love the design of the DM1 but there don't seem to be too many reviews of it out there (especially the su1400/newer version) for me to effectively compare.

 

I owned both. DM1 wins on build quality and looks imo, Acer wins on battery life and touchpad.

You won't go wrong with either. The weight difference is too small to notice.

 

Thanks Phil, that's helpful.

 

Anyone get this dm1 running on XP yet ?
I have managed to run XP in dm1, but I still got backlight issue.
The brightness level always set to max every time I reboot, already tries several Intel chipset and VGA driver, but still no joy.

Anyone have any solution regarding the brightness issue ?

Please ??
