Q: I just bought HP's HP Pavilion DV7 , the battery information in the BIOS options to see a lot of parameters, what these represent mean ah?
A: HP at present relatively ,new machine such as 4200,6230,8230 and BIOS version of higher nc4000 6000,8000 BIOS, there are a few information, which is a very succinct code, these are actually represent some parameters.
Models we tested, including nc6000/8000/4200/6220 so, for the relatively early 4000/6000/8000 may require you to upgrade to a newer bios can see the battery status before this one.
BSN .......... battery serial number (battery SN)
C1 .......... battery nominal capacity, unit: mAH (capability)
C2 .......... battery's actual capacity, unit: mAH (capability)
C3 .......... battery's current capacity, unit: mAH (capability)
ME .......... maximum error limit (maximum error threshold)
CC .......... number of charge cycles (cycle count)
T ........... the current battery temperature (temperature)
TV .......... current battery voltage, unit: mV (terminal voltage)
C ........... current input current, unit: mA (current)
DV .......... design output voltage, unit: mV (designed voltage)
MN .......... manufacturer (manufactory)
CV1 ......... see below (cell voltage)
CV2 ......... see below (cell voltage)
CV3 ......... see below (cell voltage)
CV4 ......... see below (cell voltage)
S ........... battery status code (status)
Some parameters explains:
C1, HP Pavilion DV7 Battery, the nominal capacity of the actual capacity battery C2, had these two data, when someone suspect the battery can only use a shorter time, through contrast C1, which can be judge whether the data C2 caused the problem because of battery, as shown in figure 1, because this NC8000 the actual maximum capacity of the battery had only 2000 +, less than half of the nominal capacity, so if full of electricity use only after 1 hour more, is very normal.
ME, the biggest mistake can limit (threshold), initial state as freely as three, i.e. the battery can withstand the biggest mistakes should be 3 times.
T, the current battery temperature, some people think their HP Pavilion DV4 Battery also within the scope of the replacement? If the temperature is about 40 degrees in even lower, please feel free to make it.
C, current input current, as shown in figure 1, 2004, said current for battery in discharge status, current strength, as shown in figure 2, 2.004 A current for 1673, says the battery in charging status, current strength, as shown in figure 3, 1.673 A battery by external batteries, still the input current, battery power adapter for 0.
DV, design output voltage (designed by), but the actual work than the high voltage, HP adapter output voltage 18.5 V.
CV1 - CV4 refers to the corresponding core voltages, because each of these machines generally use HP six or eight core is the core of HP Probook 4710S Battery, so it should be two core of a group, as shown in figure 3, calculated voltage CV1 0, then explaining its only 3 groups, that is core with voltage battery, the six core core series, so each CV4 CV1 - the voltage is about equal to the combined should above current total voltage TV.
