Lenovo

几年前，万合天宜的网络短剧《万万没想到》里有一集，说的是一个哥们（柯达）特别愤怒地说，什么？修不好？我是给人修电脑长大的！

如果说之前换 MacBook Pro的风扇 还可以归于硬件自然磨损的话，这次就完全是我自己的锅了。怎么回事呢？我在2月16日晚间，在另一台笔记本上写东西的时候，忘记了把桌子上的瓶装水盖子拧上，接着一个没留神把水瓶给碰倒了。

去年 公司给换了一台 Asus 笔记本，不过因为这个笔记本本质上是个台式机，不便于携带，因此我又买了一台 MacBook Pro 来自用。今年一月份到匹兹堡出差，发现还是需要一台能随身携带的笔记本，所以公司又订了一台 Lenovo T530。

Lenovo laptops has bad quality.

这台Thinkpad T61是我这么多年以来用过的唯一一台：
This Thinkpad T61 is the only laptop that I have encountered in my many year usage of laptop computers:

硬盘在机器购买半年之内坏掉两块；
It has hard drive with bad sectors with only half year after purchase;

It seems that a recent ThinkAdvantage update will cause FreeBSD boot manager to have some problem (A “Drive 0” will appear as fifth option, and all other options would not work except a beep). It is possible to recover from this situation by using FreeBSD LiveFS disc (for amd64 platform):

Start from CD-ROM;
Choose “Fixit” and “CD-ROM”;
Now you get the command line prompt;
Mount your hdd to /mnt/;
mv /boot /boot.old && ln -s /mnt2/boot /boot
mv /usr /usr.old && ln -s /mnt2/usr /usr
“boot0cfg -B /dev/ad4” (Note: your SATA controller should be in AHCI mode, otherwise it should be ad0)
Then you will be able to use boot0cfg to configure the boot partition. Reboot system then everything will go well.
