Lenovo IdeaPad U550 Review


Lenovo strives to pack performance and long battery life into a midsize notebook with this delicately balanced, but roughly executed U550.

Thin and modern looking, strong Lenovo software bundle, long battery life., Pro: Thin and modern looking, strong Lenovo software bundle, long battery life

Screen has a very small viewing angle and glare., Con: Screen has a very small viewing angle

For $679, you get a very capable notebook that can handle work, multimedia and even gaming with a relative ease. The low voltage CPU works well with Windows 7 to provide enough power for daily usage, and when you add the ATI graphics, the machine can...

Lenovo IdeaPad U550 M25C2MD – Affordable ultraportables


Affordable ultraportables - these are the words from Lenovo when the topic is the U series, so we are lined up for an exciting test.

love this laptop


i came from a c2d laptop before this, and i honestly cant tell a difference in performance. highly recommend this laptop to anyone

thin, light, surprisingly fast (once i reformatted 7), sexy, numpad, great battery life

keyboard takes a little getting used to, comes loaded with bloatware. reformatting is a must

Specs are correct


The previous review about specifications being incorrect was false. I recently ordered this, and indeed it is only the model with the SU4100 and 3GB RAM. All the specs here are correct, except for the fact that the wireless chipset is broadcom (not...

This is a fairly nice laptop. About 5-6 hours of battery life during normal usage. Decent speed, good enough for everything you'd use it for. You're basically making a tradeoff for it being so light and thin

Of course, it's not a performance beast ; Whoever designed the keyboard layout should be fired. The FN key is where Ctrl should be, the arrow keys are far too small and difficult to find by touch due to the ridiculous crunched in numpad ; Screen...

Description is incorrect -- in a good way!


This 3759-5BU is actually a C2D SU7300 (1.3/3M/VT-x), not a PDC SU4100. Also, it has 4GB RAM, and 320GB hard drive. Sufficiently quick, though not fast at all. Light, and big, size compares well with a Macbook Pro 15. Perfect size and weight for a...

A bit slow, but fine for browsing, movie watching, and office work. Loaded with bloatware, but all of it can be uninstalled
