Review: Lenovo ThinkPad X130e Review

Today we look at another ultraportable laptop from over 2 years ago featuring AMD APU. The ThinkPad X130e actually has both AMD (Zacate) versions and Intel (Sandy Bridge) versions. The particular system we look at has an AMD E-300 APU (Zacate).

Two latches secure X130e's user removable battery

X130e features an user removable battery. This type of batteries usually has better aftermarket availability thus contributing to a longer service life of the laptop.


Three screws to lift bottom cover

The bottom cover is basically a large 'service door'.


Two SODIMM slots and one 7mm 2.5" SATA HDD

Even though Lenovo specifies only 8GB max RAM, there is some chance 16GB RAM might work in X130e although I haven't seen any user confirmation of it working, other than a confirmation for an Intel based X131e model running 12GB RAM. X130e also features 3 USB 2.0 ports and 1 Gigabit Ethernet port.

Bottom line:

Well, what can I say? A low-end 11.6" ultraportable featuring easy-to-access 2.5" hard drive, 2 SODIMM slots, 1 mini PCIe (WWAN), 1 half mini PCIe (WLAN). Really so there is no excuse for ultrabook designers to not include 2 SODIMM slots. Mind you this was two years ago when mSATA wasn't yet very popular so Lenovo didn't support mSATA with the full size mini PCIe WWAN slot, but of course it can be done easily nowadays. So X130e design is one of the most upgradable and user serviceable 11.6" laptops we have ever seen. The design is carried over to ThinkPad X131e (AMD version here) and ThinkPad X140e as well.

Score card:

Upgradability: 7/10
Serviceability: 9/10
Portability: 8/10
Connectivity: 6/10

Expected service life: 7 years

Review: Asus U38N Laptop

Earlier this year AMD has refreshed its low power platform with mullins and beema. In previous generation very few vendors designed ultraportable laptops with AMD cpu. While hoping more OEM designing ultraportables with the new generation of AMD APU and SoC, today we look at Asus Vivobook U38N, a rare modern design around AMD's trinity platform.

Released in 2012, Asus U38N remains one of the very few recent AMD ultraportables. U38N is designed with ultrabook in mind, despite the term being defined by Intel so using AMD platform technically disqualifies it. Clearly it shares quite a bit design cues with Asus ultrabook lines.


Unscrew the bottom cover: single 2.5" SATA, no mSATA

After removing bottom cover, one can clearly see the 2.5" 7mm SATA hard drive. U38N is equipped with 24GB SSD cache, so the hard drive should feel more snappy than a typical laptop hard drive.


Zoom in the single SODIMM slot

Even though there is a single SODIMM slot, on ASUS's spec sheet it only supports up to 4GB RAM max. 2GB is soldered on board, so the SODIMM only takes 2GB RAM. It appears that ASUS really means it. An user's attempt in installing 8GB module had reportedly run into problems with Linux, which is likely due to the lack of BIOS support of such memory configurations.

On the connectivity side, it provides 3 USB 3.0 connections but dropped ethernet port. User would need a USB 3.0 to Gigabit ethernet adapter for ethernet connectivity.

Bottom line:

A flashy design that compromises upgradability and serviceability, which gives a rather short serviceable life. It should have been very easy for Asus to include 2 SODIMM slots in the design without any impact to its thinness and weight, which could then support a max of 16GB RAM and extend U38N's usable life a lot longer. Soldering RAM and limiting total RAM to 4GB is typical bad sport of modern ultrabook designs.

Score card:

Upgradability: 2/10
Serviceability: 4/10
Portability: 8/10
Connectivity: 7/10

Expected serviceable life: 3 years

Review: Acer Aspire E 11 Laptop

After taking a look at the inner beauty that is the Dell Latitude E7240, now we turn to a latest Bay Trail laptop from Acer, the Aspire E 11. There is also a similar but better equipped V 11 model. The particular model we look at is Acer E3-111.

Bay Trail is the latest iteration of Intel Atom platform. However, its performance is dramatically better than previous generation Atoms. So generally speaking one shouldn't carry the image of slow netbooks of the past. Acer manages to make a fanless design with this notebook.

Reveals SATA hard drive, battery and system board

SATA hard drive should be replaceable with SATA SSD. However note the hard drive is of 7mm thin 2.5" form factor. Also the SATA slot is attached to system board so it may require lifting system board (sigh). There is no mSATA slot in this laptop.

The battery is secured by two screws and plugs into the system board. It's not swappable but can be replaced by user with some care.

No SODIMM slot seen yet. The laptop does have one SODIMM slot, but unfortunately it is buried on the other side of the system board.

It's clear that Acer does not intend users to upgrade RAM in the laptop. Acer doesn't even indicate whether it supports 8GB RAM or not in their spec sheet (update: Acer now indicates a max of 8GB RAM on both the dual-core and quad-core bay trail models). Given the uncertainty and troubles of accessing the SODIMM slot, the laptop wouldn't receive RAM upgrades from most users if any.

Gigabit Ethernet and 1 USB 3.0 are present. Rest USB ports are of USB 2.0.

Bottom Line:

Aser Aspire E 11 and V 11 are major upgrades from netbooks of the past. Fanless designs are appealing as well. Intel now supports up to 8GB RAM for Bay Trail processors, but Acer does not appear to want users take advantage of it.

Score Card:

Upgradability: 2/10
Serviceability: 3/10
Portability: 8/10
Connectivity: 7/10

Expected Service Life: 3 years

Review: Dell Latitude E7240 Laptop



In recent years the portable computing world has gone through some major changes. We have observed the rise of smart phones and relatively inexpensive tablets, lead by Apple's wildly successful iPhone and iPad. Both desktop and laptop seem to drop into decline. Microsoft also moves into touch interface big time with its Windows 8, essentially incorporating the touch interface into every personal computer.


Among the sea of changes, a trend of 'disposable computing' is also observed. More and more manufactures are dropping upgradability and serviceability in their designs, encouraging users to buy a new one rather than upgrading or repairing existing ones. This is causing a lot of waste, both in terms of users' wallet, and in terms of society in general and its environmental impact. It appears at least some of these design decisions are profit-driven.

So it is refreshing to see that Dell manages to preserve the traditional values in upgradability and serviceability with the Latitude E7240 design.

Single latch to release the removable battery

E7240 features a single-latch user-removable battery. After releasing two screws, a gentle push also releases the bottom cover.

With the bottom cover removed, two SODIMM sockets and two mSATA slots reveal themselves.
Dell chooses to exclusively use mSATA instead of 2.5" SATA drives, and it puts two mSATA slots so power users can expand the capacity of SSD. This is a sensible choice for ultraportables as mSATA SSD's has been catching up in capacity with the recent Samsung 840 Evo mSATA SSD up to 1TB, which means one can already fit E7240 with 2TB of fast SSD storage.

The two SODIMM sockets would support up to 16GB RAM. This should allow the laptop a generous life of many years. In my opinion, RAM capacity now plays a more important role in PC obsolescence than CPU processing power.

The laptop features the latest Intel Haswell 15-watt processors, so one can expect pretty crisp performance. 3 USB 3.0 ports and 1 Gigabit Ethernet port are present, so the connectivity of E7240 is excellent, considering many ultrabooks need extra ethernet adapter cable. 

There are some early user complaints of loud noise of the cooling fan. Apparently one of the parts suppliers provided less than ideal quality fans. One way to reduce this problem is to change the power options setting of 'minimum processor state' from 100% to 5%. Fan noise on ultraportable systems with higher-end cpus has long been hit and miss, I would love to see Dell make a similar fanless design with the Haswell ULX series processors. The last fanless Dell laptop I remember is the Latitude X1 released in 2005.

Bottom Line:

Dell Latitude E7240 is one of the most upgradable and user serviceable ultraportable laptops on the market.

Score Card:

Upgradability: 9/10
Serviceability: 10/10
Portability: 8/10
Connectivity: 10/10

Expected Service Life: 10 years
