[This review was collected as part of a promotion.] One should always have an extra AC adapter for their mobile devices. I have one permanently connected in my work space and I travel with one. Because I have had such great support from the people at Lenovo, I am happy to order from them.
[This review was collected as part of a promotion.] My old charger burnt out on me, and was having a hard time locating same product. Chat rep helped a lot made it quick and easy to purchase. Got it fairly quickly as well in the mail.
When I need to charge my laptop, it charges quickly and the adapter doesn't heat up that much even when it's being used for an extended period of time.
I am not accustomed to writing reviews and replying to company surveys; however, I was keen to write this review of my new T550 to pass on to others my surprising discoveries with this computer.
I work as a translator and the most important features for me are a good keyboard and a better than average battery life.
I have owned two other “top brand” laptop computers in the past.
Both of them were inadequate in terms of keyboard. To be honest, I had not done any research on either and I bought those computers based solely on speed and screen resolution and brand.
This time around I did a significant amount of research on the internet before making my purchase. I have certainly not been disappointed by the keyboard on my new T550. It is extremely comfortable with responsive keys that facilitate accuracy and speed.
I opted for a 256GB Solid State Hard Drive and 8 GB Memory, so I am more than satisfied with the speed of my T550.
Leaving the best for last, and this really is the icing on the cupcake, the surprise has been the battery life.
I upgraded the battery to an Integrated 3-cell (44Wh)
All the sites that I researched, and the Lenovo site itself, gave the battery life for the T550 at between 10 and 14 hours. I figured that even the bottom of this range would suffice.
The thing is: I am tired of fighting for a seat next to an electricity outlet.
Surprise, surprise: I actually can’t believe it still, and I have waited before rushing to write this, I have had my new T550 for over 2 months now and I regularly get over 24 hours of battery life.!!!
How? I simply work only on 75% brightness!
I am not employed by Lenovo so I certainly cannot, and am not, giving any kind of warranty. You should check with your dealer whether this is a freak or a normal situation.
Anyway, I am over the moon with this performance.
The only minor disappointment with my new T550 is that I added few dollars for a Fingerprint Reader; however, when I downloaded Windows 10, this function was disabled and I have been unable to reactivate it. Perhaps I will have more time soon to try and get my fingerprint reader to work.
I really don't know what I should do. Should I buy another adapter or another battery? I just purchased a ThinkPad E550 but the battery sent by Lenovo isn't recognized by the laptop except as unauthorized or invalid. At first I thought it was the battery. After I examined it I checked Amazon for a suitable battery and found one but it was the same battery! Then it occurred to me that the problem might be the AC adapter. It works fine running the laptop. It provides 65 watts. My primary suspect was still the battery until I noticed the ads for 90 watt adapters for the E550. Is that the reason the battery won't re-charge? Did they send the wrong adapter? It runs fine on 65 watts but is more power needed for re-charging the battery? Don't misunderstand. I like the laptop. I don't regret the purchase of the ThinkPad E550 or the upgrades requested but Lenovo missed a step in the processing of my order.
