unofficial upgrades and info for the X1xxe series and the Mini 10

#1 Post by ThreeIguanasPerSecond » Wed Feb 26, 2020 2:00 pm

mistakes might be present, use this piece of information at your own risk. keep in mind that i'm not responsible for any sort of damage done to your system, and that includes the BIOS/UEFI mods. if it doesn't work or worse, bricks your entire machine, don't whine in this topic. you are responsible for whatever you've done to your system, capiche?

the X1xxe series contains a total of 6 models in its line-up, although it's 7 if you count the uncommon Mini 10.

CPU__________________
Mini 10 - Intel Atom N450 @ 1.66 GHz
X100e - AMD Athlon Neo X2 L625 @ 1.6 GHz or L335 @ 1.6 GHz / AMD Athlon Neo MV-40 @ 1.6 GHz
X120e - AMD Fusion E-350 @ 1.6 GHz or E-240 @ 1.5 GHz
X121e - Intel Core i3-2367M @ 1.4 GHz or 2357M @ 1.3 GHz / Intel Pentium 967 @ 1.3 GHz or 957 @ 1.2 GHz / Intel Celeron 857 @ 1.2 GHz or 847 @ 1.1 GHz / AMD Fusion E-450 @ 1.65 GHz or E-350 @ 1.6 GHz or E-300 @ 1.6 GHz or C-50 @ 1 GHz
X130e - Intel Core i3-2367M @ 1.4 GHz / Intel Celeron 867 @ 1.3 GHz / AMD Fusion E-450 @ 1.65 GHz / AMD Fusion E-300 @ 1.3 GHz
X131e - Intel Core i5-3317U @ 1.7 GHz / Intel Core i3-3227U @ 1.9 GHz or 2367M @ 1.4 GHz or 2365M @ 1.4 GHz / Intel Celeron 1007U @ 1.5 GHz or 887 @ 1.5 GHz or 877 @ 1.4 GHz or 867 @ 1.3 GHz / AMD Fusion E2-1800 @ 1.7 GHz or E1-1200 @ 1.4 GHz or E-300 @ 1.3 GHz
X140e - AMD Fusion A4-5000 @ 1.5 GHz or E1-2500 @ 1.4 GHz
overview: all of them are soldered to the motherboard, there are no exceptions. you can't perform an upgrade unless you have the necessary tools to de-solder it, then solder in a faster CPU back to the motherboard. so the only cost-effective way to upgrade it, is to buy a motherboard that comes with a faster CPU.

the X120e is identical to the Edge 11, both hardware and software-wise. in this case, there are 6 more CPUs to choose from if you are interested in swapping out your X120e's motherboard with an Edge 11's motherboard. the 6 CPUs are: Intel Core i3-380UM @ 1.33 GHz / Intel Pentium U5400 @ 1.2 GHz / Intel Celeron U3400 @ 1.06 GHz / AMD Turion II Neo K625 @ 1.5 GHz / AMD Turion II Neo K325 @ 1.3 GHz / AMD Athlon II Neo K125 @ 1.7 GHz

GPU__________________
Mini 10 - Intel GMA 3150 @ 400 MHz
X100e - ATI Radeon HD 3200 @ 500 MHz or HD 2200 @ 500 MHz
X120e - AMD Radeon HD 6310 @ 492 MHz
X121e - AMD Radeon HD 6320 @ 508 MHz or HD 6310 @ 492 MHz or HD 6310 @ 488 MHz or HD 6250 @ 276 MHz / Intel HD Graphics 3000 @ 350 MHz
X130e - AMD Radeon HD 6320 @ 508 MHz or HD 6310 @ 488 MHz / Intel HD Graphics 3000 @ 350 MHz
X131e - AMD Radeon HD 7340 @ 523 MHz or HD 7310 @ 500 MHz or HD 6310 @ 488 MHz / Intel HD Graphics 4000 @ 350 MHz or HD Graphics 3000 @ 350 MHz
X140e - AMD Radeon HD 8330 @ 497 MHz or HD 8240 @ 400 MHz
overview: no upgrades are possible as they're all soldered into the northbridge, or CPU. attempting to upgrade the northbridge will either result in a bricked motherboard or a forced path down to messing with the BIOS just to get it to support the upgraded northbridge. even if you do manage to get the BIOS to recognize it, you won't get the motherboard to cooperate as there are obviously different pin signals and board layer requirements.

Chipset__________________
Mini 10 - Northbridge: Integrated into CPU | Southbridge: Intel 82NM10
X100e - Northbridge: AMD RS780MN | Southbridge: AMD SB710
X120e - Northbridge: Integrated into CPU | Southbridge: AMD A50M
X121e - Northbridge: Integrated into CPU | Southbridge: Intel 82HM65 / AMD A50M
X130e - Northbridge: Integrated into CPU | Southbridge: Intel 82HM65 / AMD A50M
X131e - Northbridge: Integrated into CPU | Southbridge: Intel 82HM77 / AMD A68M
X140e - Northbridge: Integrated into CPU | Southbridge: Integrated into CPU
overview: it's impossible to upgrade any of these without turning the motherboard into a paperweight, the full explanation can be found above.

DRAM__________________
Mini 10 - [slot 1: 2 or 1 GiB DDR2-667 PC2-5300 SO-DIMM]
X100e - [slot 1: 2 or 1 GiB DDR2-667 PC2-5300 SO-DIMM] [slot 2: 2 or 1 GiB DDR2-667 PC2-5300 SO-DIMM / empty]
X120e - [slot 1: 2 or 1 GiB DDR3-1333 PC3-10600 SO-DIMM] [slot 2: 2 or 1 GiB DDR3-1333 PC3-10600 SO-DIMM / empty]
X121e - [slot 1: 4 or 2 GiB DDR3-1333 PC3-10600 SO-DIMM] [slot 2: empty]

X140e - [slot 1: 4 or 2 GiB DDR3L-1600 PC3L-12800 SO-DIMM] [slot 2: empty]
overview: the Mini 10 maxes out at 2 GiB, the X100e maxes out at 8 GiB, and the X120e/X121e/X130e/X131e/X140e maxes out at 16 GiB. if you install RAM modules that are faster than the original factory-supplied modules, it'll be underclocked to the original factory speed. some CPUs or northbridges might be able to handle the faster speeds however, but that's something that i'm not entirely sure of yet.

overview: in the Mini 10/X100e/X120e/X121e/X130e, the first slot accepts only half-sized MiniPCIe cards. they also have to be PCIe-based, otherwise they will not work in the first slot (no USB lanes). the second slot accepts full-sized MiniPCIe cards, although it can accept half-sized MiniPCIe cards with an adapter. also, only USB-based MiniPCIe cards will work in the second slot as it has no PCIe lanes. please be aware that the second slot does NOT support mSATA SSDs.

in the X131e, the second slot can be used as an mSATA slot, unlike the previous models. the X140e on the other hand has no second slot, which means you cannot install an mSATA SSD anywhere else (the first slot doesn't accept mSATA cards anyway). however, it compensates that by adding a USB lane to the first slot, so it's now both a PCIe and USB MiniPCIe slot.

Proprietary Slots__________________
Mini 10 - [slot 1: Bluetooth Daughter Card BDC-2.1 / empty]
X100e - [slot 1: Bluetooth Daughter Card BDC-2.1 / empty]

overview: nothing but only Lenovo's BDCs will fit in this slot. the fastest BDC that you can upgrade to is the BDC-4 card (60Y3305, 60Y3303, 04W3824), which is a Bluetooth 4.0-compliant card. and if you didn't know, the BDC slot is not affected by the BIOS' whitelist, so you can install any BDC as you wish.

SSD/HDD/SSHD__________________

X140e - 11.6" 1366x768, 60 Hz, 6-bit, 1 channel, TN, WLED, LVDS, matte
overview: don't have much of a clue on the display panels but from what i can see, the Mini 10 has a different LVDS connector compared to the X100e's LVDS connector. i'm speculating that the X100e has a 40-pin connector and the Mini 10 has a 30-pin connector, so upgrading the panels may be difficult for the Mini 10. as for the X100e, i don't think there's a possibility for an upgrade, as there aren't a lot of 11.6" display panels out there.

the rest of the models seem to be using the same 40-pin LVDS connector as the X100e does, although i can't confirm if that's really the case at the moment.

Battery__________________
Mini 10 - ThinkPad Battery 17 (24Wh, 170g or 0.37 lbs) / ThinkPad Battery 17+ (57Wh, 340g or 0.75 lbs)

X121e - ThinkPad Battery 35 (32Wh, 200g or 0.44 lbs) / ThinkPad Battery 35+ (62Wh, 323g or 0.72 lbs)
X130e - ThinkPad Battery 35+ (62Wh, 323g or 0.72 lbs)
X131e - ThinkPad Battery 35+ (62Wh, 323g or 0.72 lbs)
X140e - ThinkPad Battery 35+ (62Wh, 323g or 0.72 lbs)
overview: nothing much to say here... there's a trade-off for either weight or run-time, that's about it. you can't attach a dock battery or an Ultrabay battery as there isn't an Ultrabay slot and/or a docking connector.

if you're wondering about the mysterious ThinkPad Battery 35: it's just a 3-cell version of the 35+ battery pack (can be used in place of the 35+ pack). was only available as an option in the X121e, the later models no longer had it as an option.

How are these devices? I know that they were developed as portable typewriters (netbooks), but how are keyboards, trackpoints, construction in contrast with normal X/T series?
Is it usable when running linux?

About 5 years ago I had an X131e for a short time
(bought cheap on eBay with password, removed it and sold it on with handsome profit).
Mine was a X131e (3367-1Z3) that came with an Intel Celeron 1007U (1.5GHz).
These machines were basically designed for schoolkids, were rather thick, but extremely sturdy.
Good for rough environments.
They run XP, Vista, W7, W8 and even W10, so my guess is, just as good with Linux.

I believe motherboards are swappable between some of the early X100e series and early Edge 11" or E100 series. E120 has a Sandy Bridge CPU.

Thanks ThreeIguanasPerSecond, for providing the reference material in this thread.
OK so I also bought a second-hand X130e that had been built for the NSW Education Department. It's BIOS is locked, but is upgradable, unofficially, to 32GB DDR3 (if you could justify that, given the BGA cpu's are limited to sub-2GHz, dual-core). Sure it's chunky, but in several years of intermittent use I've always found it a joy to use - despite the lack of a backlit keyboard or a thinklight, and no ultrabay option. With a SSD pwned from another project, it does really well in both Win10 and a variety of 32- and 64-bit flavours of Puppy Linux, thank you very much.
However, the stock TFT 1366 x 768, 11.6" screen is a little bit of a drag. I haven't found any report of anyone trying a 1:1 replacement for a better resolution screen, so I have ordered a 40 pin IPS, HD 1080 (1920 x 1080) screen to test it out. If it works, expect me to quietly buy up all the pre-loved x130e's I can find ;)
(Hmm and with the help of a dremel, I wonder if a backlit keyboard from a similarly-sized Lenovo could be shoehorned in?)

The LCD can be replaced with a (glossy) IPS screen.

Hey good catch RealBlackStuff - I couldn't find any report of an IPS/ 1080HD screen *not* actually working in the X130e, due to hardware limitations etc, so will be a useful experiment. Natch on the glossy, for mine, I ordered a B116HAN03.1 AUO LCD, matte. Fingers crossed...

It's got a 1 lane LVDS connector, 1366x768 is the max you'll get out of it. Also, you don't have an onboard DP connector to scavenge the signals off of, your sore out of luck there.
Thinkpad4by3's Law of the Universe.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

Dang - thanks for verifying that issue for me, Thinkpad4by3 - I had thought there may have been somesuch bottleneck. Ah well, hopefully the IPS will still be a noticeable advancement over the TFT. Cheers
EDIT: and you raise the issue, if I understand correctly, of LVDS vs eDP. uh oh :oops:

UPDATE: hmm realizing just how little I understood/understand of the video hardware limitations in the X130e, was not going to be a case of "just upscale your resolution and/or inverter" as I had hoped. Given the limit of 1-ch LVDS (6-bit) there are plenty of suitable TN displays that are LED backlit that are in my current budget, and comparatively few 6-bit IPS displays that are about 25-50% more expensive than their TN counterparts. Then in between are 1-ch LVDS IPS displays that are *8-bit* instead of 6-bit. Would such displays be compatible, or even desirable, for upgrading the stock X130e display? I can't find any information dismissing such a situation out of hand, can anyone on this forum give me advice?
I've emailed the Chinese suppliers to request a halt on the model I ordered (2-ch eDP) to see if I can exchange it for a similar, 1-ch LVDS (the AUO B116XW02 V0 - it's TN not IPS, but I'll take my lumps)

Re: unofficial upgrades and info for the X1xxe series and the Mini 10

Ive spent the last few days looking through every panel that would possibly fit. The one that fits bet is the LP116WH6-SLA1, having the same bolt holes, pinout, layout and specifications as your B116WX02. The only difference is the width, 278mm on the AUO panel and 280mm on the LG. It has been done though, its a bit of a tight fit. I plan on buying one of those panels.

There are others that have different mounts that could work. I checked the LVDS spec, a 6-bit signal on an 8-bit display will go back to fall back mode and use the upper 6 most significant bits. If your up for some drilling and possible cable extensions, go to panelook and search by 11.6" LVDS IPS panels.

Here's a pre-configured link for you: https://www.panelook.com/resmodlist.php ... c_family=3

^^ this is every LVDS based 11.6" IPS 1366x768 panel.

Thank you very much indeed, Thinkpad4by3, for all that really useful detail regarding unofficial display upgrades. Really appreciate you collating the summary on Panelook, and thank you for confirming my hope (or suspicion) that the 1-ch 8-bit LVDS display would sample back to the upper 6-bits. (I wonder whether the image quality would be appreciably improved over the usual 6-bit lane, or whether it would be effectively degraded overall, given the additional processing demands? But I dither).
Don't mind cable extensions - better than the LVDS-eDP adapter-type alternatives I realise now that I would need for my original choice (if it were single lane to begin with), and the practicality of a 40-pin LDVS to 40-pin eDP adapter would likely send me down a completely new rabbit burrow that I can't afford to travel.
Cheers :)

The extra 2 bits on each channel is handled by a 4th twisted pair. When connected to a 6 bit display, its just driven on 3 pairs not 4. The 8-bit display has no idea its not getting an 8-bit source, and will do nothing in response. Technically, you won't get the top colors...ie you can only get 11111100 instead of 11111111, but this should be imperceptible. Unless your doing color work on a X131e, in which case I ask why?...it should look the same except for the added colors and contrast from IPS.
