Its Samsung RV413. They dont even have it in their website from the looks of it, and in my theory, they are reusing the chassis maybe with the AMD chip. design-wise exactly like this: http://www.samsung.com/my/consumer/pc-peri...ail&tab=feature

for other laptop suggestion, I dont think i can help sorry. Me myself just go lowyat spend 5 hours trolling around huhu.

upon reading around, it does have haha. But it so quiet its unnoticable i guess. been using almost 1.5 years isk . kudos to Acer i guess for a noiseless fan

Hello!

Very well made summary. Thanks!
I observed the exact same behavior on my 1215B E450 bought in Germany. However under Ubuntu the netbook behaves normally, switching to the highest CPU clock of 1650 Mhz on demand, even while charging and a battery load under 93%. Therefore the problem seems to be linked to the netbook and Windows. I submitted this issue twice to Asus, but I have not received a answer yet.

Regards.

I want to ask, how does turbo boost/turbo core works?

I saw somewhere E450 can go up to 1.9Ghz, but never really states the operation to do it?

The turbo is limited to the graphics core of the E450. The cpu core does not have this feature.

Got a reply from Asus. A upcoming bios update will address this and other issues.

Regards.

I'm a 1215b e-450 owner.
It seemed weird to me too but i can verify OP's exact findings. All tests were conducted in identical ways.
Thank you for pointing this hidden nasty out.

Awaiting the BIOS update...

Yeah, finding it was a little surprising. But overall, much better than other laptops. The 1215B at least runs full speed when unplugged, or when charged above 93%. So it's really a matter of making sure u are fully charged or simply unplugged to get full speed. For me, I like to game without my battery in, so I still get my full speed. However, lenovo laptops are crippled if their batteries are not plugged in. I read a thread on their forum, where someone complained about the design flaw, but the engineers kept insisted it was a design FEATURE. I had been considering an x120e/x121e at the point, but after reading the thread, I struck lenovo completely off my life of brands to consider.

I assume that the speed is crippled while charging to ensure that the battery is charged as quickly as possible. However, I would have preferred it if Asus gave users a choice to either prioritize charging or speed, or give us the option to buy a more powerful charger.

many thanks for publishing your findings because i looking to buy 1215b tomorrow and i don't like surprises,you prep me up for this.

but anyway,if we uninstall all the asus energy management software,or reformat with a fresh window,will we get max speed all the time? or the problem came from bios rather than in window software?

To be honest, I'm not sure. I suspect the energy mgmt system is probably in the bios, otherwise one might have different results between Win7 and WinXP. At the core of it, I think (as I mentioned earlier) the biggest factor for the reduced speeds while charging is the less powerful adapter, so it's really a combination of bios and hardware. I remember a similar argument being made at the lenovo forums.

FYI, I reformatted my drive from win7 starter to win7pro. I still have the speed drop while charging. I kept the energy mgmt software since it will help to extend battery life.

It is a bios problem - at least Asus told me so. See post #24.

got myself a asus u36s i3 at last instead of 1215b,more than satisfied for it now with the thing it bundle with
now i can confirm that asus had did something good bout the mushy keyboard of 1215 chassis,i try 8 out of 10 1215b in lowyat had a firmer steadier keyboard,while the other 2 still has mushy keyboard,i think if you are unlucky enough u might get the old chassis where they haven't got their hand on the problem,but new chassis is much better,it still flex,but no more worse than competing model.is there anyway to confirm the new and old chassis?i don't know,but try it yourself before handing over the money will help a lot

Some news ???

The promised BIOS Update is out. The 0503 bios dated Dec 9th solves the clock issue while charging

Thank you for the swift update vase_t.

Any user knows how to get around the incorrect temperature reading of the APU core? The BatteryCare as well as CoreTemp are not able to do so. Thanks.

AMD e450 good? becuase i want to buy new Sony Vaio Y Series.

Thanks for the update vase_t. I'll do a retest to see if the new rom does what is promises to do, but it quick check seems to verify that the problem has been fixed. Glad that this issue has been neatly resolved.

Harveylee, the e450 has its plus and minuses. Whether it is good for you depends on what you intend to use it for. It's better than the older atom processors, more than adequate for general word processing and surfing, while the Radeon HD 6320 lets you do some decent gaming on the side. But if you intend to do a lot of cpu-intensive work like photoshop, 3d animation, etc., the i3 or the i5 is the way to go. Of course, it's all about tradeoff - budget, speed, size and weight.
