In perusing the daverea.com traffic stats, I’ve noticed a lot of folks arriving here from searches for various permutations of “Linux” and “HP 6710b”, probably attributable to my ongoing log of my experience running Ubuntu Linux on my very own 6710b business notebook.
Lately, I’d been experiencing a peculiar battery problem on my 6710b, so – despite their being completely unrelated to my use of Linux aboard the machine – I decided to add the symptoms and solution to the page. Here’s an excerpt…
Over the past few months, I’ve been noticing an increasing propensity for my 6710b’s battery light to flash yellow, rapidly, whenever the machine is turned off and the AC adapter is unplugged. As it began to occur more and more frequently, it became quite an annoyance – the machine can’t be turned on in this state, despite the fact that the battery has a full charge and will happily operate the computer if the AC adapter is removed at runtime.
On returning to the line, [the tech] advised me that HP would be sending a replacement battery, but if this didn’t fix the issue, I’d need to load Windows in order to use the battery diagnostic utility.
The new battery arrived in the mail the next day – kudos to HP for sending it overnight air – and I gave it plenty of time to warm up (from the 35°F ambient outside) and an overnight charge. The next day, upon shutting down and removing the AC adapter, I got the same symptom: rapid-blinking yellow battery light.
Before calling back HP tech support or – gasp! – loading Windows, I thought perhaps a BIOS update might be in order.
I burned [the BIOS update] to a CD and used the straightforward installer to flash it onto the motherboard.
From that point on, the 6710b has not exhibited the rapid-blinking yellow battery light after the machine is shut down and the AC adapter disconnected.
