联想 ThinkPad T550 笔记本电脑简短评测

二大于一。 联想的这款商务新品配备了两块电池而非一块电池。这让它获得了足以让竞争对手眼红的电池续航时间,而同时保证了硬件性能。一块LTE模组保证了所需的灵活性,数据也获得了很好的保护,而输入设备也一如既往地近乎完美。不过遗憾的是它没能配备一块IPS屏幕。

整体上,T550可以符合T系列的高端定位,相对它的售价物有所值。这是一款相对较轻,坚固而做工精良的商务笔记本,尽管不便于维护升级,但在运行中十分安静且可以保持清凉。LTE让它相比仅支持Wi-Fi的机型有了更大的灵活度。它的安全功能绝对让人满意,键盘和触控板也拥有顶级品质,而所有目标用户群所需的接口也应有尽有。

尽管它的性能对于商务用途的常见软件来说绰绰有余,但处理器在负载下的降频问题让人略感遗憾。它的TN屏幕,虽然还算明亮,但与它的售价不太相称。T550最大的优势无疑是超长的电池续航时间,对于需要长时间使用笔记本而无法连接电源充电的用户来说会十分有吸引力。需要更强性能、更优秀屏幕的用户应该可以在T550众多的配置机型中找到适合的一款。不过,问题在于这类机型是否会走进零售市场。
