Re: X300 - how's the LED screen?

2008-03-22, 15:46 PM
That's great to know that Lenovo gave control of the LED brightness to the consumer! (i.e. LEDs have the bigger range of brightness than florescence, but that doens't mean lenovo has to make that range available to us). Thanks for the info. Is your monitor on the T61p the regular wuxga or is it the wuxga+? The brightness of the former screen is 175 nits & the latter is 200 nits. (which is even higher than the x61s ultralight screen).

i believe you mean WSXGA+ rather than "WUXGA+" (which doesn't exist).   to help clear things up, cedric stated that he has a WUXGA panel (1920x1200) and those are all rated at 175 cdm^2.   the WSXGA+ panel (1680x1050) is the one rated at 200 cdm^2.

i have the WUXGA panel on my T61p and will be comparing it on thursday when my X300 shows up.   parts lookup says my X300 display is a TMD.   my T61p's WUXGA display is a samsung.

Well just for clarification, these are just common paper spec values, let's say similar to printed battery runtime values and thus these are often far away from real measured values, so you shouldn't take those for absolut representative values and instead more as what they finally only are, namely some sort of more or less vague spec value. Further there is no TFT panel on the market, which offers absolute evenly distributed light over it's surface sections, which in turn means that you won't have a specific max luminance value everywhere (on every surface sector) of the panel and so only some mean value.

For example a Z60t TFTs has according to the Tabook 180 nits, but when measured just a maximal value of ~140 nits. Other ThinkPads in the past which had been listed to have 150 nits had at best just 122-125 nits ...and so on.

I should add, that the above said is common to all notebook panels from all notebook vendors!

There are some IT related sites and magazines (...in germany we have some of them), which always do also measure the notebook displays, temperatures and/or noise levels and so on. Here are some german review/test sources...

- Notebookcheck.com (they also have english translated versions of their reviews)
- NotebookJournal.de
- heise mobil online (heise is the publisher of the famous german c't computer technics magazine)


For LED based notebook panels (those with LED BLUs) things related to the overall luminace etc. are much better and so most LED based notebook panels do more or less somehow nearly meet their advertized specs, or are at least often in some more acceptable closer range here.

the benefits of LED based screen for the end consumers are mainly due to its lower power consumption compared to the TFT based display.... also there is no mercury used in the LCD manufacturing process, very important for our environment.... also LED-LCD are much thinner and more robust (tougher and longer LED service life 200,000 hrs) compared to traditional TFT-LCD.... i tested my friend's X300 which seemed to be little bit brighter T61p, but i couldn't tell any other differences in terms image quality...

Re: X300 - how's the LED screen?

The X300 LED sceen offers a very good readable resolution of 128 dpi (1440 x 900) for a 13,3" panel in contrast to the usual 114 dpi (1280 x 800) of other usual 13,3" panels. So that's undoubtly an advantage of the X300 when compared with other 13,3" notebooks.

The display has a matt, reflexionless surface (like all Thinkpads have), but offers those nowadays mostly notebook-typical narrow viewing angles, low contrasts, but vivid colors. It's LED backlighting offers a remarkable even illumination, so to say offers a very even density here. - Some by the german c't magazine measured data values:

  • Max average luminance of 236 cd/m² so it's even quite usable on sunny days. When running on battery initially 170 cd/m² but this is changeable inside the Lenovo energy management tool via an own profile to use max brightness of 236 cd/m² instead even when on battery.
  • Display contrast 200:1, the viewing angle from top is 18° and from bottom 20°.
  • Battery runtime with the 43Wh high-capacity battery was 5.6h (7.7W) on low load and 2.9h (14.9W) when using DVD-video load. When the display was dimmed on 100 cd/m² the battery had a runtime of 5.5h, on full brightness 236 cd/m² the battery reached 4.5h. - The flexible choosable battery options do allow runtimes between 3,5h and nearly 9h.
  • The thermal system noise, e.g. the fan, was pretty noiseless and even under highest load the X300 fan only produced a noise of 0.4 Sone, which is a very good value.
  • SSD read/write speeds have been very fast 58.8 MBytes/s read and 50.4 MBytes/s write speed, thus nearly in par or even better and faster than the best usual 2.5" notebook HDDs and even faster than some desktop HDDs. Things to worry about here are just the limited capacity and of course the price factor.

All in all and so in sum-up, the X300 got very good and positive critics for a small and light to carry around notebook!

Re: X300 - how's the LED screen?

2008-03-31, 21:17 PM
So I got my X300 last week, turned it on only to find a stuck pixel in the middle of the screen... Suck.

I tried various software methods and some pressure/tapping techniques to try and unstick the pixel, but to no avail.

So I called support, who agreed to send me a box so they could fix it for me.  A week later, and they still have my laptop, only to tell me that they want to charge me $700 for a replacement.  What??!

I know stuck pixels happen, but this is just poor QA, letting a brand new laptop ship with this defect.

What are my options here?  Can Lenovo give me a replacement?  Can I return it and get my money back ? (which I would then use to buy another laptop?).  Am I stuck with a defective laptop ?

Thanks.

I am afraid that it takes more than 1 dead/stuck pixel to qualify for a replacement under warranty terms. Check here for details. You wil find the other manufacturers have similar policies. Dell, Apple, HP/Compaq, Toshiba, etc.
I doubt they will replace it but if you are really nice to the right person....who knows.
If you return it there will be a restocking fee.

That sucks. My lenovo machine also arrived with noticible dead pixels (not a X300) & other defects. I returned it & I'm currently fighting the restocking fee. Drove me nuts that a brand new machine arrived with so many defects. The tech people seemed to know immediately when I described the problem- no one seemed surprised that it didn't work right & I'm stunned that lenovo can get away with shipping bad merchandise and expect the consumer to pay for it. They wanted me to send it for repair, but I thought I'd be stuck with a lemon. I didn't believe them, but I was told that if I "worked with them" and agreed to have them fix it, that if they did not fix it to my satisfication, then I could return it for a full refund without restocking fee. Since I did not believe them (what if they said they fixed it but I didn't agree; plus what if it really was a lemon & I was stuck sending it for repair every 2 months) , I did not take them up on this offer, but maybe it could help you now get back full price (if you send it in for repair the usual return date rule does not apply - so they said anway).

Seems to me theyre setting themselves up for a class action lawsuit with big damages if it becomes clear they know the are shipping bad merchandise (thru 4 countries no less!)

p.s. to other poster- did they report specs for lowest brightess level too?

So, an update on my stuck-pixel situation.

Lenovo got me an RMA #, and is going to be taking my laptop back and giving me a refund.  They also told me that they will be getting me another X300 for the same price that I paid for it (including the EPP discount).

Sounds good to me, we'll see if they follow through!

I did get an email yesterday after talking with a price that was a few hundred more than expected.  I assume that is the restocking fee ?  Oh well.

I have a T60 (15") with a 1680x1050 display and a new X300. The display in the X300 is much brighter and has a larger range of adjustment than the T60. In fact it seems better in every way. I'm pleased with the high resolution of the screen, most portables have screens which are too small for real work.
