Below are images with temperature readings listed in degrees Fahrenheit:Unfortunately, noise was something of an issue with the fan on the 1525. The fan moved a significant amount of hot air but the noise was reasonably higher than what we hear on most current notebooks. When the fan is on low it isn’t noticeable over background noise most of the time. However, when the fan was at the highest setting we did record the volume of the noise breaking the 60dB mark from about two inches away from the fan exhaust. Again, this was a pre-production review unit, so your mileage (or decibels) may vary.Battery LifeThe 6-cell 56WHr Li-Ion battery provides excellent battery life for the 1525. With Vista’s power management running in "high performance" mode, screen brightness set to maximum and wireless on, the 6-cell battery delivered 2 hours and 53 minutes of battery life. We’re certain that the 6-cell could deliver three and a half hours of life with the notebook set to "balanced" or "power saver" mode and the screen brightness turned down.There is also an available 9-cell 85WHr Li-Ion battery for those users needing extended battery life.

One thing to mention is that with the 9-cell battery in you get an overall larger dimension for the notebook as the 9-cell battery sticks out of the back of the notebook.ConclusionOverall, the Dell Inspiron 1525 is an excellent budget notebook with good looks and solid performance. This isn’t a gaming machine, but the 1525 can handle everyday computing tasks with ease … and looks good while doing them.In short, the Inspiron 1525 is exactly the notebook that the Inspiron 1520 should have been in the first place. Even though the 1525 is arriving a little late to the party we suspect it’s going to be a very welcomed guest in many homes.Standard aspect ratio business notebooks are becoming more difficult to purchase these days from different manufacturers, but Lenovo has pulled through for another generation with the ThinkPad T61.
