Pro: The matte screen is the best part about this notebookCons: I have been getting many reports by other customers that this notebook is causing, THERMAL SHUTDOWNS, because of its poor engineering. The majority of consumers have reported this problem and I have not found a recall for this particular model, but there should be a recall of all HP 630 notebooks.They have reported the screen getting garbled at first. The matte screen phases out to a corrupted mess of lines. During this occurrence the fan starts spinning at full RPM.About 5 to 10 seconds and the notebook shutsoff.RED FLAG: DO NOT BUYHP 630 Business Notebook: Been using for only 2 weeks JUST ARRIVED 6/2/2011CPU: Pentium P6200(2.13GHz) 3MB L3 CacheDisplay: 15.6″ LED backlight, Anti-GlareVideo Memory: Shared system memory – Intel HD GraphicsGraphic Type: Integrated CardMemory: 4GB DDR3 1333 1 x 4GB __ 204-Pin DDR3 SO-DIMMHard Disk: 320GBDVD Super MultiLAN and WLANDimensions: 14.8″ x 9.72″ x 1.25″ – 1.41″ ___ Weight: 5.5 lbs.Battery: 6-cell (47 WHr) Lithium-Ion battery ____ 65-watt AC adapter Problem: Business Notebook randomly has a corruption on the screen. I have monitored my pc right before event occurs and have used CPUID to monitor system temperatures. Temperatures stayed at a cool CORE #0_82*F and CORE#1_97*F. Screen randomly blanks out to a longitudinal pattern of strings on screen. Fan starts to get really loud during the previous onscreen corruption. Fan builds to a point that shuts the notebook off. Upon turning back on I get a message: Thermal Shutdown. Prediction: Notebook is not overheating to begin with> It does not overheat until the screen corrupts to the string pattern.USER COMMENTARY OF Troubleshooting: Troubleshooting UNFINISHED: EU stated that the unit overheats. User: No, Overheating is not exactly the cause of the problem. Temperatures seem to remain below 160 degrees F. OR 71 degrees C during times of high use and idles at 98 degrees F. on average. I have been monitoring the system using CPUID and it does not show signs of overheating necessarily. EU mentioned that the unit shuts down. User: Yes, the unit shutsdown while in the middle of a task, such as installing a program or running a CD. Before shutting down something very unusual happens. The screen does not completely black out or shut off, but it stays on showing a longitudinal pattern of various colored lines, as if the screen fails. Advised the EU to clean the vent NO GO. User: NO, Cleaning out the vent is not a solution. This notebook is 2 weeks old. There isn’t dust trapped inside the notebook. I could understand if it was a year old. Two weeks isn’t enough time to collect a significant amount of dust or lint. It is pretty dumb to advise cleaning vents. FAN IS WORKING PERFECTLY FINE. EU mentioned that the fan spins very fast. User: Yes, Fan Builds up RPM upon the screen being corrupted. Once screen messes up the fan starts spinning faster. The machine gets hot after the screen corrupts causing the fan to build RPM until PC shuts down automatically. EU when tries to power the unit gets a message thermal shut down.User: Yes, the screen being corrupted causes the shutdown. Upon turning the machine back on the PC shows a Bios Report of a “THERMAL SHUTDOWN.” Summary Troubleshooting: The overheating of this machine doesn’t occur until the screen becomes corrupted. Upon the monitor going out the machines FAN is then building RPM (to compensate for heat);therefore, overheating is not necessarily the issue. What is causing the screen to go out? Could it be a Hard Drive ERROR? IF OVERHEATING IS THE CAUSE: Why is the fan delayed until the screen goes out to compensate for the sudden build up of heat?
