LG C1 Core Duo nVidia Go7300 UltraPortable 10.6" Tablet PC Review

LG C1 10.6" with Core Duo and Go7300

Some relatively better shot photos to start with ( sneaked from NBRs sister site, TabletPCReview.com)

​

Introduction

The quest for a small and powerful laptop is an elusive one.
Powerful laptops like the XPS M1710 IMHO cease to be laptops while the really small and light ones are seriously strapped for power with a puny core solo or similar.
The LG C1, from that POV is a rare find. It is perhaps one of the smallest form factor laptops around. Yet with a dedicated graphics chip and a Ultra low Voltage Yonah processor isn't really a puny excuse for a computer either.

LG C1

​

This is a fairly expensive notebook, but the cost is justified by the performance capabilities of the immensely tiny package.


Build & Design

The Piano Black finish with a 1 inch thick casing gives the notebook a very sleek & elegant look & feel.

The build quality, which is a very important parameter for any notebook buyer, especially portable notebook buyers is as good as would be expected from a machine at this price.
The casing (which I am not sure what material it is made of) feels extremely sturdy and shows no sign of any flex at all in any area.

LG seems to have done a good job with the choice of materials and the machinen feels solid all around.
As with all tablets, the weakest (apparently) area seems to be the solitary rotating hinge.

The machine has an extremely thin profile and I really cannot find fault with the design except a few nitpicks

• Piano black finish is fingerprint magnet. Check the package contents picture to see for yourself how it looks after picking it up 2-3 times
• The LCD bezel houses the HDD, wirelesss, Num Lock and Caps lock lights on the left side. I am used to it now but the flashing hdd light can be a bother to start with

For comparisons' sake, an XPS 1210 next to a 1710 :hap5:


​

Screen

The screen, a 1280x768 resolution widescreen, was another area of concern for me.
I am very very finicky when it comes to screens and even the slightest amount of backlight bleed or non-uniformity in lighting bothers me no end.

Technical details on this screen seem to be hard to find, but given the extremely uniform backlight and the ultra slim top panel profile, I suspect this means uses LED backlighting but cannot say for sure.

Some online reviews complain of graininess on the screen (due to the touch panel overlay) but I could not notice any.

the horizontal as well as vertical angles are as good as I have seen on any laptop.
The colors are thoroughly vibrat.
The screen truly leaves me with no reason to complain.

For some, the glossy screen can make viewing difficult in direct sunlight, and even in lower light conditions you may notice reflections. However, glossy screens rule the consumer laptop segment and I am not complaining.

Video Playback




​

Speakers

The speakers are oddly enough placed on the bottom, presumably to save space, as real estate is really in short supply on this tiny machine.
Expectedly, the speakers are tinny with very little bass.
The hardware based XT surround Does a fairly decent job though and the speakers can perform upto taks for watching a quick movie or two.


General Performance

Using a regular Core Duo and Core 2 Duo based setups (T2400 and T5500), I had expected the ULV 2500 to be sluggish but was pleasently surprised to see that is not the case. I am a habitual multi-tasker, and the system never feels sluggish.
This is perhaps due to the fact I am running XP on a 1 GB setup. I am not planning Vista on this machine for two reasons,
1) I am not a big Vista fan and still prefer the cleaner, non garish looks of XP
2) The system currently 2X 512 sticks, 1 a SO DIMM (Regular Laptop RAM), the other a micro DIMM
Unfortunately, micro DIMM 1 GB sticks are hard to find and prohibitively expensive ($ 250 US +) and I am not sure if Vista will behave well even if I replace the regular SO DIMM 512 with a 1 GB to take the total to 1.5 GB

HD Tach

the 1.8" Toshiba HDD isn't a scorching performer but ain't too bad either



Gaming Performance

A Go7300 with a 1.2 Ghz Core Duo doesn't sound like much, and it really isn't
It still is heads and shoulders above the regular GMA950s and I am still amazed as to how did LG manage to cram in a dedicated GPU into something this small

The only game I have tried so far is GTA San Andreas
The game is capped at 25 fps and the game indeed ran at the capped 25 fps till 1024X768 and high detail settings (No AA)
At 1280X768 (native resolution of the LCD), the framerate dropped to 18-19 at some places

Next I removed the frame rate cap from the game console and this time, the frame rates hovered around the 40 mark at 800X600, 30-35 at 1024 X768 and 18-27 at 1280X768

Just for the heck of it, I installed coolbits and set the nVidia system properties for detecting an optimal overclock
The auto generated OC was 476 mhz (from default 350) for the GPU and 952 mhz for the memory (from default 700) ..a massive 36% :O
GTA SA at this OC ran butter smooth at native 1280X768 and high details

I still haven't tried any other games on the setup but I think it should be able to handle pretty much all Third person and racing games with elan, while newer FPSs will need to be scaled down to lower res and medium-low details to run at fair framerates.


Heat and Noise

For its size, the LG C1 has fairly powerful components in a very small space, but there really isn't any noise (It doesn't have an internal optical drive, remember ) and runs fairly cool.

The OCed GPU touched a max of 65C (so far)
The CPU temps hover between 35-47 C depending on the load.
The vents on the left side can get quite warm when the graphics card or CPU is working hard but the bottom stays cool throughout.

Keyboard and Touchpad

Keyboard view of LG C1


​

The keyboard on the M1210 is surprisingly a full-sized keyboard and the keys have a good feel to them.
The way LG managed to cram in a full sized keyboard was by chopping away the width of the side keys.
Thus even though the qwerty keys and the alphabet rows are full sized, the less oft used keys on both the right and left hand sides (bksp, Caps lock, enter etc.) have been chopped from the sides
For those interested in more details, The size comparison photo with the XPS 1210 (which has a regular full sized KB) will be of use.

The keys have a short throw and the tactile reponse is decent. There is no learning curve or getting used to period involved and I could type at my regular rates on this system almost immediately from the first use.

The touchpad (thankfully) is Synaptics (And not Alps which I thoroughly detest) and is as good as touchpads get
The touchpad keys are a tad too small though and people with fat fingers will have a hard time on right clicks.

Tablet Performance

First the good bit, the small size , the ligh weight and the powerful performance make this system a very handy tablet. I did not buy this system with the intention of using it as one, but keep finding myself using the system as a table quite often for some passive browsing or reading PDFs/Docs

Now the bad bit, the screen on flip does not change its orientation automatically.
You need to press a Fn key + rotation combination to do that.
The Fn key as well as a few other hot key combinations are however available for usage with the screen flipped and allow you to scroll, hit enter and gain access to some often used applications.

The handwriting recognition is decent but I personally prefer the tap keyboard when in tablet mode.
The screen requires a slighly tight press from the stylus in comparison to PDA styluses but that is presumably due to the fact that unlike a PDA, your palm may need to rest on the screen while using the upper corners of the screen and too sensitive a screen wuld create problems in such scenarios.

Personally, I feel tablet usage makes sense while doing passive reading/browsing or when minimal keyboard usage is required since the OSK or the handwriting recognizer cannot come close to the effectiveness of a keyboard.

Battery
​

NHC shows a drain of 8.5-11W on 70% backlight and regular usage with wi-fi on and browsing.
Thus the 3 cell battery lasts 2-2.5 hrs wile the bigger 6 cell (53 whr IIRC) should give 4.5- 5 Hours at this rate.

OS and software

This notebook came with Windows XP Tablet PC edition with an option for express upgrade to Windows Vista.
I haven't as yet sent out the express upgrade for to LG though and I don't intend to either.

Surprisingly (And thankfully, there was nearly no bloatware on the system) but just a couple of LG utilities (hot key support, Connection manager etc.)
Except the connection manager, which I found thoroughly useless and uninstalled, there was no other cleaning up I had to do.


Service and Support

LG claims a Next business day On location support (LG notebook there service is outsourced to Wipro peripherals like Dell) and though I haven't had a need to to use that (hopefully not), I have had a pleasent experience with Wipro when their service engineer came over to fix my XPS M1210s whining noise last year

The website based support however is terrible and pathtic to say the least.
The LG support site is chaotic and messy and God Forbid if you ever need to find updated drivers for the setup.


Conclusion

When it comes to laptops, I am a very demanding customer.
I can get extremely nitpicky about tiny details. (If in doubt, check my previous review on the Sony Vaio C22 here
http://forum.notebookreview.com/showthread.php?p=1867543#post1867543

This time around though, I am pleased to say that this tiny rig lives upto the stated promise.
It is a beautiful rig, packs a punch for its size, and needless to say, is extremely tiny and light.
I never thought I would use it as a tablet but of late, I have fallen into the habit of fipping the screen around and using it as a tablet while lying down on bed.
It delivers in every way and apart from the lack of an expresscard slot and the fact that the tablet could use an active input, there isn't anything I can complain about at all


Pros

• Fast performance for the size
• Applause for LG for putting a deciated GPU on this tiny a rig
• Ultra Compact size
• Decent battery life
• Solid build
• Extremely light
• Probably the sleekest External ODD I have seen with a laptop

Cons

• Expensive
• Tinny speakers
• Lid collects fingerprints
• No Expressccard slot
• Single RAM SO DIMM slot, the second slot is a micro DIMM
• Terrible support site

 

Nice review.
The 3d marks score is amazing for such a small laptop!

 

yup...
also, i still haven't had a chance to try additional games, but since GTA SA works perfectly fine, I think most TPS and racing games should also run well..
I am not a big FPS fan (I get nauseated while playing them) so the gaming performance seems to be sufficient..

PS: Added tablet usage pics above too

 

Really like the looks of LG notebooks, but they're pricey =/ still great review!

 

Yeah, LG always seem to have sexy designs. I myself like fingerprint magnet lids - I like to marvel at beauty Gadgets

Shame they seem to still not sell in the UK yet

 

Nice and detailed review, I am glad you find the performance of the ULV processor to be good - I have never used one myself so it is good to get a first-hand account of what they are capable of. If you don't mind, could you run this test here:
http://forum.notebookreview.com/showthread.php?t=123570
. . . so we could compare it to other dual-core machines?

I purchased a Lenovo ThinkPad X61 Tablet PC on Friday. I actually had considered the LG C1 but dismissed it when I saw the screen was only passive.

 

Great thread there Chaz
I'll run wPrime tonight from home and post back...

Meanwhile, I'll also spread the word on wPrime by linking to that thread on some of the Indian Technology forums that I am active on...


The X61 is a great machine though for some funny reason, it is overpriced in India while the LG was priced much lower (around $1700)
That and the Go7300 pretty much sealed the deal for me

 

Great review.
Could you please post the cost in Rupees

 

Strange, if I recall in one review, one person had said the Geforce 7300 had even worse performance than the GMA 950! There must have been a mistake and I'm really impressed they managed to put a GPU into this size. I just wish they'd increase the 10.6" screen to 11.1", there is a difference and I really like it.

 

that dude may have been running it on the WDM drivers :rofl:

Actually the 10.6" seems fine to me but then I am used to the 12" on the XPS 1210 and this wasnt a big change to adjust

 

Very nice review.
This is probably the only sub-12 inch tablet with a dedicated GPU

Btw, in the review, under 'Keyboard and Touchpad', the picture caption says 'Keyboard view of the XPS M1210' but the actual picture is of the C1 keyboard. Just pointing that out

 

Thanks, edited and fixed

Also added the wprime results @ 71.953 seconds for 32m

 

OMG
Who'd expect this from a <12" machine

 

That is interesting - it is the opposite here. In the US the LG C1 with the same specifications as yours runs $2,600. The Lenovo X61 on the other hand starts at $1,640 (at least until the sale ends on June 18 - then the starting price will go to about $2,000) - I picked up mine with a few extra things for $2,127.

I agree, the Go7300 is extremely tempting. It is astounding that the engineers found a way to fit it in such a small chassis.

Thanks for running the test - could you post them in that thread so Gophn knows to add them to the table on the first page?

 

I just wish Lenovo would make the X60/X61 widescreen. Ugh to standard screens.

 

So how much does this run in rupees? I might have to consider buying one next time I go back to Madras....

Awesome little tablet...

 

just arnd the 75K mark if you look arnd for deals ...expensive, but worth it ....

 

Wow that is a great price, actually! Good review. I am debating getting this or the TZ. Hmmm...

Edit: Whooops...sorry for reviving such an old thread. Does anyone know if the C1 has been updated? I can't seem to find any info on it locally and we get tons of LG models here in the Middle East.

 

It looks like Toshiba R400 .....
