This. These cheap keyboards are very annoying.
I hope Lenovo produces the old IBM style business quality keyboards for their brand new models.
@Lenovo: have a look at your great T410 keyboard, build them again: http://cdn6.bigcommerce.com/s-blhknq8/product_images/images/... (only the cursor keys are a bit too small, otherwise great)
edit: "F keys" part readability
Why would they practices selling replacement parts that could cost you half of the laptop price just to replace a casing?
I never understood the point of removing these. I think it may just be cutting costs, trying to save a few cents on the custom shape LEDs.
modern SATA drives doesn't matter if they are still mechanical or SSD's don't work the same, your OS doesn't work the same when you save a file it doesn't mean that it's being written that moment, it can be in RAM, it can be in your HDD's cache or it can be written down.
HDD activity LED's haven't been doing anything real for over a decade now...
From what I can tell, this feature is called "Device Activity Signal", and it essentially says the drive can use the P11 pin of the SATA connector to indicate activity, and the board can use this to electrically drive the LED, there's no need for high-level protocol support.
Obviously this won't detect writes to the buffer, only when they are actually pushed to the disk, but when there's heavy IO, the two are usually correlated.
Here's a doc by Samsung about DAS from 2014: http://www.samsung.com/global/business/semiconductor/minisit...
As a user, I can tell you that while I obviously can't relate a single "blink" with a write to a file, the link between having a bunch of processes hung waiting for IO and a heavily active LED is quite noticeable - and can be useful if the UI is completely blocked.
Samsung for example only supports it on the DC (datacenter) series of their drives which is for enterprise storage the DAS in this case is only enabled in certain modes to note if the drive is active or spare/standby or to identify a specific drive there is no actual write/read iop activity feed back in SATA drives.
Also dear lord was that document auto-translated? I've expected this level of English from a 3rd tier Chinese OEM not Samsung...
>4. Samsung SSDs for data centers are
Basically, Samsung SSD 845DC PRO and 845DC EVO support the SATA 3.1 specifications. However, Samsung has adjusted only the DAS feature as “enabled” by default to make the LED blink regardless of the SATA specifications in the host systems.
I have to wonder, why? The OS can do that quite well in software.

More moving parts means more potential breakage.

Different customers have different preferences, but the majority of people do like thin, almost as much as light.
All that aside, check out the proposed ThinkPad Retro. Looks quite promising to me.
If something can be turned on or off, I don't want to rely on the OS to do it. Give me a hard switch. This even goes for system power.
I click on the wireless icon and click "turn off". It's good that command-line syntax exists, but that doesn't make it the only way, or necessarily the simplest way.
For that matter, some laptop models offer a function key to do the same thing.
For that, the laptop must be on and booted. The main advantage of the hardware rfkill switch is that you can flick it to disabled before booting or waking up the laptop, so that it doesn't even try to connect before you can get to the wireless icon.
(I've done that before: on a plane, want to use the laptop, which is sleeping in the bag; just flick the rfkill switch and open the lid to resume from suspend.)
Fair point. However, planes don't require turning off wifi or bluetooth during normal flight anymore. (And even when they did, no actual harm was done either way.)
When I last flew (domestically, last year), the instruction was still that devices could only be used if they had an "airplane mode" function. Things might be different in your country. (And yes, I know normal 802.11 probe request packets won't do much interference, if any, to airplane systems. Still, it doesn't harm to flick the rfkill switch to disabled.)
Sometimes airlines fail to communicate that well. A friend of mine had a flight where they first warned against using any device with any kind of radio transmitter, shortly followed by "please enjoy our in-flight wifi".
Oh wait, they're doing that already. And the usability sucks.
I'm running i3, not GNOME. I want a damn hardware switch when I need to flick wireless off. I don't want to have to keyboard OR mouse around to do it. You want a plain black slab, go buy one. There's a market for what we want, and ThinkPads shouldn't be that plain black slab. Leave that to Apple.
If you have to drop to a console prompt and run rfkill in order to disable your wifi... then the flight attendant will have no idea whether your wifi is enabled or not.
He or she WON'T gawk with impressed amazement that you're a Linux user. For that matter, neither will anyone here.
That's just patently wrong with regards to latching ThinkPad lids, as the latch is actually saving the lid hinge from wearing out prematurely.
(which is one of the reasons for my recent model downgrade)
> I have to wonder, why? The OS can do that quite well in software.
You can't think of any nice reasons why it may be nice to have hardware blocking software from reactivating all the antennas on your machine at will?

Also, a battery and power supply LED that is not _on the back of the device_, so I can actually see them while using the device.
I don't really get this complaint. They're all scissor-switch keyboards. I've got an old X220 lying around, and use a T450s for work. The chiclet keyboard on the latter is significantly better. In terms of key stability, I think the new Macbook keyboard is actually the best.
- Non-chiclet keyboard with decent layout
- HDD and network activity indicator lights
- Hardware wireless-off switch
- Latching lid
They certainly don't need to make it any thinner -- I've had to carry some Macbooks around and the sharp edges are not very hand-friendly. I think 1" throughout is about right for a laptop thickness.
