To check if your PSU is eligible for replacement, please first unplug the product or switch off its power. On the front of the PSU, you will see a four-digit production code: it is formatted YYWW, where “Y” refers to the year and “W” refers to the week. All products before and including week 41 of the year 2019 are potentially affected. You may have an affected PSU if the first two digits (i.e. the year) are below 19 or both of the following are true:
- The first two digits of the code are 19
- The last two digits of the code are 41 or below
For example, a PSU with the code 1835 is affected, while a PSU with the code 2005 is not.
