It is this range of Intel processors CULV intends to do – quite moderate speed for demanding applications, but with lower power consumption than a conventional mobile processor. CULV stands Consumer Ultra Low Voltage, which means that the processors do not cost a fortunate, but they come at very low voltages (and therefore low energy consumption). The INSPIRON 2650 SERIES is one of the first laptops CULV we’ve seen, so we wanted to see if the ultraportable have always wanted.

I have all experienced poor battery life on my new laptop that are typically less than six months old. There may or may not be a high failure rate for this battery model, and this page details my experiences in diagnosing the health of my dell inspiron 1721 battery and obtaining a replacement under warranty.

Determining Battery Health

There are several methods of determining your battery’s capacity relative to it’s initial specification (aka “health”).

• Press and hold the status button located on the bottom of your A1185. The five LED lights will initially display your battery’s current charge (five lights is charged, zero lights is discharged), and if you continue pressing the status button for three seconds the lights will blink off and back on again, now displaying the health of your A1078. If zero lights appear your battery is operating at greater than 80% of its specified capacity, if five lights appear your battery is operating at less than 60% of its specified capacity. This information was pulled from the D620 User Guide.
• If you enter the system BIOS by pressing “F2″ during the Dell logo while booting, there is a “Battery Health” option under the “Sytem” menu which gives a qualitative assessment of dell 1721 battery health.
• The power manager under FC6 tracks the maximum capacity of your Apple A1148 at its last full charge and generates a health percentage based on the factory spec charge for your battery. To view this information, right-click the battery meter in your gnome panel, select “Information”, and expand the “More” area of the “Device Information” panel.
• If you kept your initial Windows XP install, there is a battery health meter under the Dell Quickset applet in the lower right hand corner of the screen that gives the same information that is available through the system BIOS.

Obtaining a Replacement Battery

Of course, you always have the option of purchasing a replacement Toshiba pa3384u 1brs from Dell (9-cell or 6-cell), or simply living with degraded battery life. There are some circumstances where you may be able to obtain a replacement under warranty, though. If the BIOS/Quickset health gauges are showing the battery as failed even though it’s less than a year old, dell inspiron 1721 battery will be replaced it under warranty. According to the phone rep that I spoke to, a battery is considered to have failed when operating at less than 50% of its rated capacity.

When I called, my battery was five months old and operating at 50%-60% of it’s capacity (5 death lights, BIOS noted lowered battery life but did not pronounce failure, FC6 power manager rated health at 56%, observed Toshiba PA3191U-1BAS life was 50%-60% of expected). I was able to successfully make the case that the battery was clearly borderline and would certainly be replaced within a month or two, and that doing so now was an opportunity to provide excellent customer service whereas forcing me to wait would serve no purpose other than irritating me. To his credit, the phone rep immediately acknowledged that my line of thinking was reasonable, spoke to a supervisor, and was able to authorize the early replacement.

Conclusion

I love my laptop, and in general I’m very happy with it. It does look like there’s a trend toward premature inspiron 1721 battery failure, though, and if your situation is severe enough you may be eligible for a warranty replacement.
