I've owned this dell laptop for about a year now and it has worked great. model M5010, amd triple core proccesor 2.3 Ghz, 6 gigs of RAM, 64 bit operating system, and has a ATI Radeon HD 4250 grafic card. It runs windows 7 home premium software. i have with it the AC adapter that works fine with it.. this computer is very versatile. I've used it at college for word documents, its 6 GB of RAM let it multi task very well. i have no issues having 5 or 6 big programs up and it not skipping a beat, ive used it for online gaming and it works real good. runs quietly, and never heats up to much. screen is aproximetlly 15", has blue ray player, WiFi, WebCam, eather net ports, usb ports, headphone/mic jacks. hinges are still in good form and shape so the screen is sturdy and doesn't wobble, and its high gloss finish still shines like new. its even got Pro-Engeenieer (Pro-E) software downloaded onto it if your into that type of stuff. i get about 3- 4 hrs of battery life when using it on power saver mode. the space bar is semi slackly, meaning it wasnt as good as it once was. sometimes i find myself writing two or three words together to create one big giant word. but nothing drastic. it works fine and you adapt to its sensitivity. reason for selling is i am upgrading to a new computer. my name is Chris, feel free to email me about this device if your interested or have any questions.
