You either need to buy a 90W adapter to run without the battery, or plug in your battery!

Thanks for clarifying that. The battery is in. The system is slow.
Community members have suggested a few things to check, but this is becoming a Sherlock Holmes mystery. Who dunnit?

Just wondering if you've tried CPUz to check the frequency of your CPU. Lonney suggested that, but I didn't see you post any results. If it's slower than Core 2 Duo, usually only several things can happen:
1) CPU is stuck at lowest frequency (Use CPUz to check: http://www.cpuid.com/softwares/cpu-z.html)
2) Your harddisk is broken or nearly broken, which leads to your OS spend most of time scanning bad sectors. (Use HD Tune to check)
3) If you are using an HDD, make sure you leave at least 10% free space for each partition, especially the system partition
4) You've installed sth, that keeps scanning the disk or using 100% CPU... (Or could be a trojan)
From your HD Tune report, it's likely to be the 2nd case. Reallocated event count should be 0 for a healthy disk, and any number larger than 0 means a pre-failure condition. Your count is terrible... (Paper from Google: http://research.google.com/archive/disk_failures.p
Please consult Lenovo support. They have an HDD scanning tool, and if that reports an error, you should be able to get a replacement. Select you model at http://support.lenovo.com/en_US/, then go to Diagnostics Software. I recommend that you use a bootable CD since your system is already slow.
