Concerns and Questions About Lenovo's T460p (2016)

2016-04-04, 4:29 AM

Hey guys, 

I have purchased the Lenovo T460p and I am thinking of returning it due to a number of issues. I have not yet received it. It is in the final stages of manufacturing. 

 

1. One of the first reviews of the T460p has reported:

'A bigger problem is the temperatures of the processor: Even with CPU load-only by Cinebench, it reaches almost 90 °C (~194 °F) and even up to 93 °C (~199 °F) in Prime95, which results in a slight clock reduction from 3.1 to 2.9 GHz. In this case, the temperature will level off at around 90 °C (~194 °F). When we also stress the graphics card as well as the CPU with the tools FurMark and Prime95, we can also see the effect of the TDP limitation at 35 watts. The latter has to suffice for the processor and the graphics card. The full performance is only available during the first 30 seconds, when the chip can consume 45 watts, before the limitation at 35 watts sets in. The temperature climbs to 95 °C (~203 °F) in this short period. The processor levels off at 2.7 GHz, while the graphics card runs at 900 MHz.'

My question is has anyone benchmarked this laptop and found a similar result.

 

2. One of Lenovo Support partners on this forum has reported he is able to use a Transcend 128 GB M.2 2242 SATA SSD in the optional WWAN slot. Has anyone confirmed that this type of storage chip is supported in the T460p (market ready model). 

 

3. When I first purchased my t460p there was no option to upgrade to the 940MX, but the NEXT DAY lenovo updated their website and now offer the Nvidia 940MX as an option for $143 AUD. I am not able to cancel my order, because they have informed me I will have to wait until it is delivered, which won't be for another 10 days. Lenovo really should get their act together instead of wasting my time, because I can't even alter my order. 

I was wondering if the extra heat pipe from the 940MX impacts CPU temperatures. Is it possible to retrofit a 3rd party 940MX or buy one separate from lenovo and fit it in this laptop?

 

4. I have also ordered the overpriced 256 GB PCIE NVME SSD. I recently found out with great difficulty that it is using SATA Express (up to 16 Gbps, x2 speed), which is well behind the speed offered by companies like Dell who use Samsung 950 Pro NVME SSDs in m.2 x4 slots. This is something to keep in mind for prospective buyers. I know there are a lot of big data people out there.

I purchased a T460p earlier this month and I can say that I'm very happy with it (apart from a small issue with the trackpad, which should be solvable through a driver update though).

 

I run Windows 10 Home on it and have a virtual machine running Ubuntu for my development work. I haven't put it through heavy computing loads yet but using it normally doesn't heat up the CPU a lot, and the fan is surprisingly silent as well. Compared to my T430 the palm rest doesn't heat up very much at all.

 

Concerning the GPU it doesn't seem to impact CPU much, I tested the 3D performance by playing Crysis 2, which runs smoothly at 1280 resolution without overheating the system.

 

I use a Transcend 512 GB SSD in the WWAN slot, which works like a charm.

 

The battery performance is as advertised, when in energy-saving mode the power consumption can go down to 7-8 W, which gives you about 6.5 hours with the 45 Wh battery and 10 hours with the 71 Wh model. Personally I'd recommend choosing the 71 Wh battery, as you get an additional 35 % capacity for just 16 € and the weight is almost identical to the 45 Wh model (and the form factor is also identical). The model 0C52862 batteries (e.g. for T440 20B6, 20B7; T440s 20AQ, 20AR; X240) are compatible with the T460p btw and available cheaply online, so no need to buy an "original" T460p battery, which are offered for much higher prices it seems. I'd also recommend to stick with the basic RAM/HDD configuration (4 GB RAM and 500 GB HDD or 128 GB SSD) and upgrade those components yourself, as Lenovo overcharges them A LOT. I bought an extra 16 GB 2133 RAM for almost half of what Lenovo ask for such an upgrade, same thing for the SSD. Installation of custom components is quite easy, just follow the steps in the maintenance manual.

Do you use the Transcend M.2 drive as a boot drive, or for storage?

I use it as a boot device, as that's the most interesting use case. I have a 2 TB spinning disk as secondary storage, which I use mostly for archiving and data. Overall it works quite well.

 

My only issue on Linux is that I can't get my external 4k monitor to work in full resolution and at 60 Hz, which is something that I can live with though.
