Did I kill a component on my Jornada 690? Power drains like crazy!

Hi,

I just got myself a used J690 a week ago, and I must say that I've been very happy till this power problem came up a couple of days back.

What happens is: When I power off the H/PC the screen is blank but still backlit, causing the battery life to drain even when not in use. Is this normal? Did I fry something? Is is an unseen setting somewhere I have to tweak? Would appreciate any imput on this thanks.

have you tryeid resetting it? there is a reset button above the tab key u need to press it with the stylus (pen thing)

yep countless times! a couple of times I forgot to hook it up to a wall socket, and it drained the backup battery too - think 3 changes in a week.

i really like the gadget i really do but hooking it up 24/7 isn't exactly my idea of a mobile device....please help.

for anyone who might be interested in what are installed, although i doubt that these are giving me problems:

Standard CE 2.11 suite
Standard HP suite
128-bit encryption patch
Prism 802.11 driver

Gee ... maybe you wanna try unplugging the wifi card before you sleep at night. Wifi cards are known to keep Jxx HPCs awake at night, because of a system check at 12:00 (or so). If the wifi card is inserted, it will prevent the HPC from suspending ...

hope this helps.

PS: Hello fellow Singaporean!! How's things back in Singapore?

Another thing you may want to consider is buying a new battery as like all nicad or nimh batteries they do tend to lose their ability to hold a charge. Especially if you do not maintain the battery properly...

I looked them up and they about 30 american dollars, and it never hurts to have a spare... might be a good place to start, rather than junking the whole HPC.

thanks all for the pointers.

nopes Snappy! i don't keep the wifi card plugged in when not in use - the power consumption's a nightmare. the backlighting's driving me crazy - it's heating up the flip-top like the crazy weather here in SG with me these days.

Lose Canon -- correct me if i'm wrong, but i don't think it's an issue with the battery not holding a charge. my problem seems to be my HPC not powering off properly - think blank screen + backlighting - which drains my HPC in 7 continuous hours. but thanks for the pointer anyway, i was thinking about a spare anyhow!

Loose Canon, Where did you find the Battery? I might get a spare as well. If I ever get my 680E that is.

PDA internal battery for Jornada
680, 690, 710, 720 and 728 series
Lithium-Ion, Part No. F1262-80001. More Details
7.2 Volts 1150 mAh $38.95
http://www.jornadabattery.com/

*DISCLAIMER*
I do not endorse their product or is affliated to them!

The default battery on a 720 is 1500mAh....do I sense that they did a *repair* job like you,
and soon me, Snappy!?

hehe ... possibly!

and, in case u didnt read the other thread, I soldered on the older 2 batts in parallel ... so now I think the extended batt pack of mine is 2400+1500=3400++mAh!!

Loose Canon: the batteries in a jornada 690 aren't ni-cad/ni-mh, but li-ion!

ProgramSynth: no repair job, they're probably the original 680/690 batteries.
and i'm planning battery rebuild too! at least to 2200 mAh!
a crazy idea: i just saw an extended battery on ebay = 4500 mAh. that could be 6600 mAh just kidding! but.. now i'm tempted to buy it...

maja06: did you try a real, long hard reset? take all the batteries (li-ion and backup batt) out for at least several hours!
i'm afraid it's a hardware fault.. but try this!!

maja06, sounds like a failure in the backlight control circuit. It either could be the control circuit in the inverter for the CCFL (cold-cathode fluorescent light, the backlight of LCD displays) or it could be a power control circuit on the mainboard.

Can you still adjust the brightness settings? Is "Touch screen to power on" enabled? Long shot, but try adjusting those.


cmonex, I have one of those extended batteries. They're huge! Triple the size and weight. They definitely make the 680 more ungainly, but, it does give ya a handle.

hi Brain_Recall!

i'm still thinking about that extended battery. is it worth 106 $ (+shipping+etc)?
the size isn't so bad, is it?.. does it really last for 24 hours?
thanks

Got GOOD NEWS. My 680E has just shipped last night. Should see it sometime next week.
Oh BTW, I got a NEW Battery from HP for $53+ Tax+ Shipping. Total of just under $67. This is not a standard battery. Its a 1950mAh. So its a little bit larger than standard. Which is 1150mAh. Not as big as a F1840A. Which I was told by them is Discontinued and has been for several years. So the ones on Ebay may not have 100% life.
