Characteristic for mainboard fuses?

[Briefkastenopa]

A couple of weeks ago, I did some high resolution scans of the mainboard for different models and marked all fuses I was able to locate. Below you find the boardview for the T420 together with a list of fuses (current, voltage, package size). Unfortunately the silk screen does not give the characteristic of these fuses. Should I order slow blow or fast acting? What has worked for you in the past?
