This is a Toshiba dynabook B55. The top cover shows signs of wear, such as scratches. Also, some screws are missing, although this doesn't affect functionality. There is a white discoloration on the keys, possibly dirt or paint flaking. Memory: 4GB, HDD: 500GB DVD drive installed No accessories included. An AC adapter is available for 800 yen. It is a compatible product and not a Toshiba-branded one, but it doesn't affect operation. For 1000 yen, I can add 4GB of memory, upgrading to 8GB total. Removing all memory and the HDD will result in a 1000 yen discount. Items can be combined with other products, but please check the notes in my profile regarding combined shipping. Please refrain from negotiating any changes other than those listed above, as I will not respond and will delete the inquiry. ★ If you are in an eligible area, I can offer the AC adapter for 600 yen instead of 800 yen using Eco-Mercari shipping. If you want the AC adapter with Eco-Mercari shipping, please contact me before purchasing, stating your preference for Eco-Mercari and your prefecture, as not everyone is familiar with the system. ★ To expedite shipping, I may switch between Yu-Pack Mercari and Rakuraku Mercari without notice. If you have a preference for one or the other, please let me know in the comments. However, please be aware that this may delay shipping.
