A few days ago, I bought a Lenovo T510 to replace my previous computer. What was my surprise (and disappointment) when I discovered that it was only possible to record from the integrated microphone. And not from streaming audio, for example, as I could do it on my previous computer!
After 5 or 6 phone calls to Lenovo hotline, I got the confirmation that this was effectively the case.
Lenovo, tried to save money by inserting a cheap sound card?
