A. You can have a read on this thread to obtain the ICC Profile for the T420 along with instructions.

Q. What's the best method of cleaning the rubber finish on my ThinkPad E425?
A. View this thread to see how others take care cleaning the rubber finish of their own ThinkPads.


There was no E425 Owner's Thread so I thought I'd get the ball rolling and start it myself.


UNDER CONSTRUCTION...

 

Edit:
When I purchased my Lenovo E425 it came with the A4-3000M. While honestly sufficient for me, I simply wanted more out of my notebook. According to Lenovo, it is also capable of utilizing:

AMD E2-3000M APU Dual-core Processor (1.80 GHz, 512KB L2)
AMD A4-3300M APU Dual-core Processor (1.90 GHz, 1MB L2)
AMD A6-3400M APU Quad-core Processor (1.40 GHz, 4MB L2)
AMD A8-3500M APU Quad-core Processor (1.50 GHz, 4MB L2)​

1. I bought, tried & sold an A8-3500M. It worked and was an easy swap. Being a 35W quad, I'm sure heat and energy consumption increased to some point. I can't remember testing it but it wasn't really noticeable. Reason for swap; I wanted the 6620G and the two extra cores.

2. I also bought, tried and currently use an A8-3510MX. It works, memory runs at 800Mhz (CV 1600), and BIOS/mobo accepted it without issue. I regret not going straight to this one first saving cash money and skipping the A8-3500M altogether. The MX chip being a 45W APU does consume more energy and generates more heat. It was noticeable right of the bat. I remedied this by under-clocking/volting while on battery (or plugged in too when I want to run cool and quiet) and not doing anything intensive like browser, flash, streaming video, office productivity and so on. Currently, idle is in the 45-55 degrees Celcius but it depends on room temperature & Power Plan of course. I also use TPFanControl (version 0.62e) for that extra control over my system. Max temps at stock range from 70-80 degrees Celcius. Reason for swap; I wanted to use my CV 1600 RAM to its fullest potential and increase gaming/igpu performance.

I have been testing these settings for Maximum Battery Life. It slows my system down quite a lot but its still fine for me for those light tasks I mentioned.

My E425's A8-3510MX energy consumption according to CPUID Hardware Monitor looks like this after under-clocking/volting:
19.25W -> 15.50W = 3.75W difference

My gf's g4 A6-3420M like this:
15.25W -> 12.50W = 2.75W difference (roughly this, I'll double check next time)

Old Review​

Since none of this information existed for my model and I'm pretty much the only one on the entire forum that owns it, I took the risk of being the guinea pig. You're probably going to have to do the same. Was it worth it for me? Yes. My only regret being not buying the $75 A8-3510MX first.

I recently purchased a Lenovo ThinkPad Edge E425 from Lenovo Barnes and Noble Exclusive store. I was in the market for a 14" laptop with an AMD APU and found the E425. At the time, it seemed like a good choice for a few reasons which met my needs. It includes Lenovo's chiclet style keyboard which is pleasant to type on and the matte display that's easy on my eyes. I ordered mine with an A4-3300M but it is also available with an AMD E2-3000M APU. In the Lenovo Manual, it states that the A8-3500M APU is compatible. In the " README for ThinkPad Video Features (AMD muxless PX4.0)" text file for the Video Graphics Drivers for the E425, it states"

This package installs the AMD VGA driver to enable AMD Graphic Device.

Pros
-Great Synaptics touchpad with multi-touch gestures, UltraNav Trackpoint
-Matte display
-Solid construction
-Good overall performance

Cons
-Lacks USB 3.0 port(s); can be added via ExpressCard
-Battery life is not even close to what Lenovo promises (about 3-4 realistic hours)
-1366x768 is okay but 1600x900 would've made more sense


Quick Take: If you want a low-cost laptop that is built to business standards then the ThinkPad Edge E425 is great option. It lacks some of the features of the higher-end ThinkPads but at the same time provides a great keyboard, touchpad, build quality and that same great ThinkPad Business Warranty. For students and small business owners, this notebook makes for a great companion.


Overview



Build and Design
Even though this is a "only" a ThinkPad Edge, its build quality is superior to many other consumer laptops. Again, for the price I paid I am very happy to report that there is no chassis flex whatsoever. The plastics do not feel cheap and one of the best things about this laptop is the metal hinges. The lid does not wobble and the hinges feel solid. The lid has a really nice rubberized texture which makes it easy to grip. However, there is a bit of flex from the lid when in the closed position.


Ports and Features



Screen and Speakers
The screen can get very bright and the matte finish is AWESOME! I can actually use this laptop in direct or indirect sun light without having to raise the brightness too much. Colors, blacks, and the contrast are fine for me, I wasn't expecting a super high quality display for what I paid for it. I don't have any complaints with the screen but others might see it as a weakness (1366x768). For my student and small-business needs, the display is sufficient. I don't do any photo or video editing so display quality was not top priority. It looks like an upgrade to an HD+(1600x900) display from a T420 is possible. I cannot confirm this as I've yet to attempt the swap but they do share screen sizes and part numbers. I'll update this with any new information when it becomes available.

The sound can get pretty loud in a quiet room but are not great in noisy environments. The speakers lack bass but at least they don't sound too tinny. The speakers are good for those quick jobs but when i park my E425 at my desk, I use my 2.1 speaker system. No other complaints in this department.


Keyboard and Touchpad
The keyboard is one of the best I have have ever used. It feels comfortable, roomy, and just pleasant to type on. My hands and fingers never feel cramped. I wish the matte finish would last forever but daily use will make the keys shiny and look worn. That's the case with any keyboard, not just this particular computer.

The touchpad and trackpoint both work flawlessly. This is the first laptop i own with a trackpoint and so far i can see why so many people like it. Sometimes, its better/easier to use the trackpoint than to use the touchpad. But, I really like Synaptics touchpads as they usually provide good feedback and sensitivity, not to mention the multi-touch gestures are very responsive. I prefer my Bluetooth mouse any day but for those times when one is not available, the touchpad and trackpoint are ok too. The lower touchpad buttons feel a bit mushy, they should have been a little more firm.



My Lenovo ThinkPad Edge E425 review unit has the following specifications:

-14-inch HD anti-glare display (1366 x 768 and 300 nits)
-AMD A4-3300M APU Dual-core Processor (1.90 GHz, up to 2.5GHz TurboCore, 2MB L2 cache, 35W TDP)
-Integrated Radeon HD 6480G
-Discrete Radeon HD 6470M 1GB GDDR3
-4GB DDR3-1333 RAM (1x 4GB; upgradeable; 32GB max supported)
-320GB 5400RPM Hard Drive
-802.11n wireless network adapter (Intel Centrino Advanced-N 6205s)
-Internal Bluetooth v3.0
-Integrated 720p webcam
-Optical drive; DVD burner
-1-year limited warranty
-45WHr polymer battery
-Weight: 4.6 lbs.
-Dimensions: 13.03 x 8.9 x 0.74 inches
-Price: $1,499



Performance and Benchmarks
The hard drives feel slow to me now that I got use to having an SSD. The stock HDD was only a 5400rpm drive so to me that's not fast enough. I recommend an SSD to everyone.

The graphics are awesome! Considering what I paid for the laptop, I'm very satisfied with AMD's APU graphics performance. I wanted more graphics oomph so I swapped the stock A4-3300M for an A8-3500M. The difference between the 6480G and 6620G is very noticeable. The 6620G can play GTA IV, COD BO, Battlefield 3, Crysis 1 & 2, and many other modern titles at 1366x768 at "low-to-medium" graphics settings. Older games run without a problem. I like to play Minecraft and the 6480G can handle it just fine but I wanted the 6620G. Be cautious when buying AMD APUs from ebay. The first A8-3500M i purchased (from a Chinese ebay seller named "promise-forever") was crippled. The second A8 I bought from a US seller functions perfectly! The cpu side can be overclocked easily and safely using FusionTweaker. I prefer FusionTweaker over K10STAT because of ease of use and simplicity. I just wish there would've been a stronger discrete-GPU than the 6470M.

Heat and Noise



Battery Life
The battery lasts an average of 3-4 hours, which isn't that great. I can squeeze out 5 hours but only if I turn off the wifi, lower the brightness to the lowest level, and basically do limited work like typing. I was really hoping for at least 6 hours without a breaking a sweat but I guess that's just the difference an AMD system makes compared to the previous Intel system I had. This computer will be replaced within the next year so I'm not too bothered by the battery life. It does get me through a couple classes and then some so I'm fine with what it is for now.

-Battery life test results (higher scores mean better battery life):



Conclusion
This laptop is reasonably well built, above average for the price. I would recommend this over the Intel E420 because Id much rather have AMD's stronger integrated graphics than Intel's HD3000. Even though the cpu may be slower, the average user will never tell the difference anyways. Even at stock speeds It never really feels slow. If i want a little more performance, then an overclock is easily achieved. This in turn puts it in the i3/i5 territory. If you're looking for a solid laptop under $500 with great integrated graphics, this is one to consider. Lenovo warranty service is superb too!

How's the heat and battery life on this?

 

Honestly, the battery life on the 6-cell battery is not very good. With light use 5 hours is possible, and heavy-use 3-4 hours or less is what I'm getting. I have even undervolted a bit in order to extract the most out of the battery. The optional 9-cell battery is an alternative.

As for heat and temperatures, I'm using a 2.7GHz overclock and while gaming I don't go above 81 degrees Celsius. Temps range from 76-81 degrees C. At stock clocks heat is not even an issue. I wanted to OC my APU so naturually temps did increase but I managed to keep it at a safe comfortable level. This laptop runs very cool to the touch but when under full load the case get a bit warm. The warmth is not unbearable but I would not want to game on my lap with it unless it was on battery only and in "Power Save Mode."

 

Where did you find E425 with a A8? I've really like the E425, but I can't seem to get fine with A8 anywhere online. Did you purchase the A8-3400M online and replaced the stock APU?

 

I'm glad to see an owner's lounge for this notebook. I almost got this intead of my Z575, but the lack of a hardware wifi on/off switch was kind of a deal breaker for me.
As I have said already so many times in other threads, I'm very impressed with Llano. I kind of wish in hindsight I would have gotten the A6 model instead of the A4, but I might at some point upgrade it in the future.

 

My E425 originally came with an A4-3300M, the most powerful APU available from Lenovo at the time (the only other option being an E2-3000M). I was able to overclock the A4 upto 2.7GHz without heat problems and saw an increase in overall/CPU performance but ultimately I wanted the stronger 6620G.

Foolishly I purchased a used fake A8-3500M from a Chinese Ebay seller. I say fake because it did not operate like an A8-3500M was suppose to. Instead, its clock frequency would stick around 1.7GHz and the bus clock would be stuck around 67Mhz. Apparently, I wasn't the only one with that problem trying to upgrade to an A8. Since then I returned the faulty APU back to the Chinese seller. I tried my luck a second time and bought another A8 from a USA seller and succeeded. Everything works as its suppose to. The A8 can be overclock very well and the 6620G was a big step up from the 6480G in the A4. The 6470M helps in games like Crysis 1 & 2 with the use of asymmetrical crossfire too. I doubt will ever be able to get an A8 in an E425 from Lenovo now, Trinity is just around the corner.

The e425 was a good deal for me. Sure we know that AMD's cpu performance isn't the fastest but for my needs I don't find it lacking. The APU graphics are also enough for my personal needs. The build quality and keyboard are superb and the matte display is nice. I didn't expect a premium display for $463 but it does the job well. The touchpad and pointing stick are very easy to use and the ports are laid out efficiently(I'm right-handed). My only complaint come from the poor battery life (4 hrs avg).

As a side note: I managed to get my girlfriend an "open-box" HP Pavilion G4 with an A6-3420M for $327 from ebay. We both love it, performance is amazing for the price. It was a drastic improvement over her previous Gateway NV55C (Intel Pentium P6100). She uses a couple photo and video editing applications so the quad core apu was a great choice.


I agree, Llano is/was a good stage in AMD's development. For many informed users, Trinity is going to be a very popular choice. AMD is doing something right.

I would say try and keep your eyes peeled for an A8 if you plan on keeping the computer for a while. I understand your want for more apu performance (an SSD always helps make things faster). I paid $120 for my A8. Otherwise, wait till Trinity and beyond.

 

Anyone with a Lenovo ThinkPad get this error with Windows 8?


Lenovo Settings Power_There is a battery error_01 by davidc646, on Flickr

I am not getting this in Windows 7 and according to Lenovo's Power Mangager my battery appears good. Note 180 cycle counts

Power Manger_Battery Health_01 by davidc646, on Flickr

I installed the Power Manager for Windows 7 version 6.32 (on 8) that downloads with W7 System Update for my E425 using Compatibility Mode -> Windows 7 -> Run as Administrator.

It installed fine, it works fine and hasn't caused any noticeable errors. I even think the Battery Error that I showed in the last page went away as It hasn't come back. When I was getting the Battery Error, I only had the "Lenovo Settings Dependency Package for Windows 8 (32-bit, 8 64-bit) - Notebook" driver installed and nothing else.

EDIT: It appears I have installed an older version. The latest Power Manager for Windows 7 that I found was version 6.36. I also found a "Desktop Power Manager for Windows 8 ThinkCentre version 3.00.0006." I'm not sure what the differences are but I am going to test both out for now. The W7 version is actually dated more recently (newer) than the W8 version (older).


Note: I installed all the Windows 8 drivers for my E425 from here:
Drivers and software - ThinkPad Edge E425

Not all of my system drivers are yet available so I had to install Windows 7 E425 drivers like the Power Manager/PM Driver and the keyboard shortcuts with On-Screen display. Everything seems to be working ok, but it would be best once Lenovo updates ALL the drivers.

Note: This is what the W8 Upgrade Assistant said regarding my drivers and hardware from W7:

I stopped again into this laptop :|

have couple of Qs (for the A8-3510mx):

- can you set battery charge limits in the power manager ?
- does the integrated GPU lower clocks when the CPU is running on max clock (like Trinity) ? ... or both can run at max clock ?
- how does the integrated GPU compare to the dedicated GPU ? ... are they about the same in performance ?
- I'm guessing the MX is a unlocked chip of some sort. How high can you overclock the CPU part ? ... that affects the integrated GPU as well, right ?
- can you disable the dedicated GPU in BIOS ? ... or are you having any problems with programs not running on selected GPU when both are operating ?
- is the wifi card supporting 5GHz ? ... can it be upgraded ?
- can you post GPU-Z screen of both graphics cards ? ... that one here is for 6480M, not for the 6470M
- do you have any 3DMark06 screenshots ? ... while I know the program is CPU dependent more than it should, it still gives prospective comparison with older laptops.
- I'm guessing the dedicated GPU is soldered to the MB so no upgrades there, but can you overclock that one somehow ?
- does the "64" setting of TPFanControl work to spin the fan to the max ?

I think that's about it. Hope you find time to answer some of those questions, cause I may become the second person on here to own laptop like that, lol.

EDIT:

alright this review has a GPU-Z screenshot: ( )
http://www.looknews.us/news-1410893-Choice-for-value-AMD-E2-3000M-notebook-full-review.html

and that would be the 6620G
http://www.legitreviews.com/images/reviews/news/gpuz-v0-5-8.jpg

 

My answers are up there!

 

thanks for the feedback, highly informative

if you could, post some 3DMark06 scores (and some GPU-Z shots). I hope at full CPU speed (2.5GHz) the score to be around 5,000 3d marks for the 6470M, and probably a bit lower for the integrated gpu (at the standard 1280x1024 test resolution), which would put the laptop at the level of the T420 + nVidia 4200m.

but then if the dedicated 6470M could be overclocked then that would be golden I got little disappointed to see a 32 bit memory bus for the card from the GPU-z screenshot on the review that I posted earlier, not sure if that is the case though.

- it's with 1024MB GDDR3 right ?
- and is the main HDD bay SATA2 or SATA3 ?

thanks again.

 

No problem, anything to help. Sorry I've been late to reply, been busy with my new (full-time) job. I'm working for a computer store troubleshooting and repairing computers.

- it's with 1024MB GDDR3 right ? YES, the 6470M/7470M has 1024MB GDDR3 VRAM
- and is the main HDD bay SATA2 or SATA3 ? The main HDD bay is SATA3 (6gbps) and the optical bay is SATA2 (3gbps). There's also an eSATA+USB2.0 combo port and the ExpressCard slot is Generation 2, and will accommodate a USB3.0 ExpressCard if you want to use USB3.0 devices.

These screenshots were in Windows 7 Ultimate x64, AMD 12.11 beta 8, and AMD chipset drivers and Cap 12.11. btw...

Anyways, Here are the GPU-Z shots:

As for the 3DMark06 tests go, I could only do my test in 1280x768 (default). 1280x1024 WAS NOT available for me. Still the scores surpassed what you expected so that's a good thing. I tested at stock frequencies and overclocked to 2.5GHz.

Here are the results for SG (single gpu, dual-graphics disabled) at stock frequencies:
6620G, 1.8GHz A8-3510MX

Here are the results for SG (single gpu, dual-graphics diabled) at 2.5GHz base and 2.8GHz turbo frequencies (notice the CPU score increase):

6620G, 2.5GHz A8-3510MX

So 301 point difference for the 6620G and 267 point difference for the 6470M (2.5 GHz x 4 @ 1.2000 V, 2 x 4 GB 1600 CL9 9-9-9-24 DDR3 1.5 V, )


Just for fun, here's my curent WEI scores:

There's an E425 with the A4-3300M at the Lenovo Outlet right now for $421.68

 

thanks a bunch for the info, I'm surprised to see the internal GPU working better than the dedicated one, heh

on that note, if the ExpressCard is type 2 then one can add eGPU setup with great success - like increase the 3D performance 3 times (300%)

as for the 3D scores I guess those would be around 5000 if you ran it at the standard resolution for the free version. In this case you'd probably have to hook it to external monitor that has higher than the notebooks resolution so that 3DMark06 can run at 1280x1024. I guess at the time this was the most available/desirable resolution that most people wanted, heh.

thanks again for the post, I've been looking at that 425 in the outlet for quite some time.
