Hello community,

recently I bought one Ideapad 330s-15IKB, but when I received the package, I have seen that the model that came for me its the 330s-15ARR, so I quickly downloaded the hardware manual of the 15ARR to see if its worth it ask for the exchange, I see that the heatsink of the processor cooler reach just one slot, not two like the 15IKB, so here goes the questions:

• What does that means? (See images bellow) 
• Its worth to me ask for the exchange of the right model that I buyed or I will not loose something so important?
• What the differences between those models?

Thanks!

Thanks for your answer,

Well, I see here that the type model is 81JQ0000BR.

This Ideapad 330S-ARR has AMD Ryzen CPU not Intel CPU. The "330S-15IKB" has Intel CPU.  If your intention was to have Intel CPU you should return the notebook. If the CPU type is not important to you then if you should keep it may depend on what the rest of the configuration is... Ryzen 5 or Ryzen 7 ? How much RAM, and HDD/SSD? etc.

If you go for the AMD version, you should know beforehand that the device is known for an audio playback delay over the headphone jack and a nonfunctional standby due to defective audio and energy management drivers, plus a possibly horrendous Realtek 8821CE or 8822BE WiFi adapter which drops connectivity all the time. Those haven't been fixed yet. This especially affects the 330(s) and 530(s) models with AMD CPUs.

IKB=Intel Kaby Lake

ARR=AMD Raven Ridge

This ~2-3 second delay after ~15 seconds of no playback is based on the audio driver, and I think that the standby also causes problems for you, right? That can be "fixed" by disabling the Realtek Audio chip in the device manager.
