I have two sticks of 1GB DDR memory made by Hynix but labeled for IBM/Lenovo. One of the two sticks is defective. With Crucial or Kingston, both of which have a lifetime warranty, no documentation is required for replacement. With Hynix, however, defective memory has to be returned to the OEM vendor. Hynix does not deal directly with end users.
The memory was originally installed in a machine that is long gone. There is no way I could produce the original receipt without going through several hours' of work. Is Lenovo honoring the Hynix warranty without a hassle, like Crucial, or am I out of luck? Normally I wouldn't worry about it, but DDR is getting expensive.
