The HP Pavilion dv9000 is part of a series of notebooks made by HP that use Core Duo processors and Nvidia graphics cards and have an HD DVD drive installed as standard equipment. The dv9000 is not without its problems, however; HP refused to admit the problems existed until David Berlind wrote about them in his blog on ZDNet.com on October 22, 2007. That was when HP finally took action to replace faulty parts.
According to the HP website, a manufacturer's defect in the hardware causes a host of problems that concern various aspects of the dv9000 series, among other notebook series. Because of such problems, HP is offering an extended warranty of an extra 24 months on top of the original 12 month warranty, which comes with the purchase of the notebook PC, or the 24 month warranty, which is an additional purchase over and above the 12-month option. This extended warranty only applies to the series affected by the defect and only if the notebooks are displaying certain symptoms. Some of the symptoms that affect the dv9000 series are problems with the display, problems with the wireless network card, problems with overheating and power supply problems. If these symptoms are noted, the customer is asked to return the notebook to the place of purchase so the faulty parts may be replaced.
Overheating and Power
The problems with overheating are caused by a faulty switch in the fan on the processor. The problems with the power supply also concern the battery directly. The battery light will not come on, even if the notebook is plugged into the wall with the AC adapter connected to it and it is working properly. In some cases, the notebook will not start at all, even if it is plugged in and the battery is connected.
In addition, if the processor overheats, the computer will not start when the power button is pressed. This overheating is often attributed to the LCD display not working, but when an external monitor is connected, the monitor itself works fine because the monitor is powered separately, not by the notebook PC's processor. In either case, the customer is asked to return the notebook to the place of purchase so the faulty parts may be replaced.
Problems with the display are numerous and consist of different symptoms including the display not having power at all and the display not working even though an external monitor works fine. Some of the known causes directly relate to the overheating problems, as when the processor gets too hot, the display will blink out. If any of these problems happen, HP asks that the customer return the notebook to the place of purchase to replace the faulty parts.
The company recalled the network cards that allow the HP Pavilion dv9000 to connect to the Internet. The recall states that a defect in the network card's connection to the motherboard causes the device manager not to recognize the card's installation. In other words, the HP dv9000 thinks it has no network card installed and therefore cannot connect to the Internet. HP requests that customers return the notebooks to the place of purchase to have the motherboard replaced.
