    I have a T550 with German keyboard layout and would like to purchase a US keyboard and replace it. Will I be able to do it myself?

  2. Rated 1 out of 5


    The function keys are also tiny and tinier than the previous X230T, W500, W400 lenovo models i had. This part of the T550 keyboard is definitely toy like buildt. Odd to use.

    It makes working with the function keys (used in different contexts, by eg software developers when debugging and others) quite cumbersome.

    Also (software developer) colleagues who have 4 core cpu laptops (from 2013 & 2014) (as i said elsewhere too) have laptops that are much faster (my T550, state of the are 16 GB RAM, 500 GB SSD, i7 CPU 5600U) has a 2 core cpu and is much slower … freezes a lot

  3. Rated 1 out of 5


    I’m a developer and bought the T550 for a job i did.
    It has a two core CPU, but i was mislead by the i7 5th Generation hype.
    You will find no review on Youtube on elsewhere claiming that it is desk top replacement. The reviews i have seen, will not even mention it’s performance in relation to the McBook Pro or the Dell XPS 15.

    Why did i buy it? The Hype. Lenovo Claims it is a high-end “Business Laptop”. Desktop replacement? — well i guess i’ve been duped.

    I should have bought the XPS 15 which similiar to the Macbook Pro 15 has a 4 core i7-4712HQ (MBP has a similiar 4 core CPU I7-4870HQ)

    The CPU is an i7 “4th Generation” CPU, but it is (in my opinion) faster than the 2-core i7-XXXXU “5th Generation” CPUs, sported by the T550. I am writing this because i had colleagues with the DELL MX4800 & DELL MX3800 laptops in the office, sporting similiar “4th Generation” 4-core CPUs (their machines were purchased in 2013 & 2014) Their compile times where at least twice as fast. And my T550 had serious problems dealing with extra monitors. The T550 has an i7-5600U CPU. These CPUs (i think he U stands for “Ultra” low energy), it use less energy and allows the user more battery life.

    But if they do not perform, it like driving a 5th generation Vespa because you get more gas mileage and it is quieter, than on a 4th generation BMW motorcycle.

    As a developer my laptop needs CPU muscle and no heat on top, allowing the wrists to remain near the keyboard the entire day. If the fan makes a bit of noise or if i have to plug it in every 3-4 hours, it is more than worth the compromise.

    Even as i write the this review, my Internet Explorer has about 15 Tabs open and i have two sessions of Visual Studio running, skype, a couple PDFs open, Word is Open. And the mouse freezes on me. It is slow.

    My MBP is also opened on my desk — similiar load. It has no Problem. It makes some fan noise sometimes. So what. Better that it freezing up on me because of the load.
