This PC has had its CPU replaced with a Core i7-4702MQ. This is a listing for a PC I was using as a sub-machine until recently. It has been updated to the latest Windows 11 25H2. The memory is 8GB in the first slot and 4GB in the second slot, for a total of 12GB, but you can expand it to 16GB by replacing the memory in the second slot with an 8GB module. The memory can be easily replaced by removing the back cover. As a heat対策 for the laptop, I have cleaned the fan and applied grease to the bearings, and I have set the system's cooling policy to passive and the CPU usage to 98% in the power management settings. As a measure to prevent battery deterioration, the charging capacity has been limited to 80% using a dedicated utility. There are scratches and minor paint剥がれ on the top cover, and a slight dent in the SSD cover on the bottom. The keyboard has a shine. The sound quality is so-so, so I recommend using a Bluetooth speaker, etc. The LCD panel has been replaced with a new one, but a pinhole-sized green dot is visible on the left side of the screen when starting up and when displaying dark images. I didn't mind it when watching Netflix or YouTube. Previously, it took about 20 minutes for the green dot to disappear after startup, but now it disappears within a few seconds of startup. However, I cannot guarantee this. Currently, it is operating normally, but I will only provide support for initial defects within 5 days of receiving the product, such as the PC not turning on or Windows not starting. The PC listing policy is disclosed in my profile. Please note that this product is not subject to price negotiation.
