Re: Dell Inspiron 17R 7720 "Your Battery is Temporarily Disabled", Battery LED Flashi

Cn4 :pin5 (psid) voltage ???????????? Should be 3.3v normally

jbat1: Smbdat0 , smbclk0 voltages ?????????????? Should be 3.3v normally

jbat1: Pbat_pres# should be low

CHECK WITH AND WITHOUT BATTERY CONNECTED (ADAPTER CONNECTED)

Hello dycc,
thanks for head-up, appreciated your help,
i do have voltages as per it should be, pls check below
Cn4 :pin5 (psid) voltage 3.3v (with battery & without battery)
jbat1: Smbdat0 , smbclk0 voltages 3.3v (with battery & without battery)
jbat1: Pbat_pres# with battery 0.06v & without battery 3v
since my batter drain & goes 0% due to not used so i guess that's why jbat1: Pbat_pres# with battery showing 0.06v, so is there any way i can charges battery without laptop? i do have 110V AC 30V 10A Digital DC Power Supply so if this can charges battery than your help will save my batter to get dead, (attached Digital DC Power Supply image)
your further help will be highly appreciated,
Thanks

Did you change pr3, pr3 and pr6, you can put 33ohm or 22ohm resistor. Just try.

i'll try later, coz seems like PR3, PR6 looks fine, further i'll wait for @dycc instruction whether it need to change or not, coz i did voltages test as advised by dycc & those test looks fine & normal, Thanks for help bro,

it could be a fault in the battery pack, it does contain a microcontroller and several temp sensors taped to the cells.

that is not possible coz as i said earlier i did checked my both batteries in other same model Dell Laptop and both batteries working fine, so issue is with motherboard, will wait for @dycc further help, hope will resolve this issue,
Thanks

SINCE SMART BATTERY EXCHANGE INFORMATION (battery temperature , Battery Capacity .......) WITH HOST CONTROLLER THROUGH SMBUS BEFORE LAPTOP TURN ON, it's may be A DEFECTIVE HOST ITE8518 at smbus side.
the charging ic also can trouble smbus line .

Sorry for noobi question but what i need to do now?

[dycc]

Re: Dell Inspiron 17R 7720 "Your Battery is Temporarily Disabled", Battery LED Flashi

replace charging ic bq24707 and if it's still the same issue ,replace host controller ITE8518

Hi, I'm from Poland and I wanted to thanks you for helping me fixing my Dell. I had the same problem as OP and I found a bad capacitor - PC5 marked on the diagram (near EC58, EC59, EC60 someone mentioned earlier)





I removed it, connected the battery, and...

it helped! no more "operational temperature" notification, charging works as expected, anyway
here's its location on the board:




(pardon my messy soldering)

The photos were taken yesterday. Today I've replaced the bad capacitor and assembled the laptop. Works splendidly. So thanks again!

pin 1 and 2 voltages ?????????????

Re: Dell Inspiron 17R 7720 "Your Battery is Temporarily Disabled", Battery LED Flashi

@ma_ko you had same issue what i mention in starting? neither laptop getting power from battery nor it charged? or your laptop just not charging battery but it can power on with battery?

@dycc do you think i should try this how @ma_ko did? since i already ordered charging ic bq24707 on Aliexpress & waiting to arrived so i replaces it,
waiting for your comments,
Thanks.

Re: Dell Inspiron 17R 7720 "Your Battery is Temporarily Disabled", Battery LED Flashi

Replace these caps only if it shows short, else it doesnt make sense. You can get them in plenty from any laptop scrap mb.

most likely you have problem in battery output line. Check those lines carefully for any shorted caps or mosfet.(two similar looking pins at the extremes of battery connector-one side is gnd and the other side is output +12v)

thought you checked the board, as @mcplslg123 have asked ,but i realize that you didn't do it

jbat1: pin1 and 2 ohm value (battery and charger disconnected , black probe of multimeter on ground and red probe on pin 1 and 2)

jbat1: pin1 and 2 diode mode value (battery and charger disconnected , black probe of multimeter on ground and red probe on pin 1 and 2)

jbat1: pin1 and 2 voltages (battery and adapter connected)

Dear dycc,
yea that's true i not checked above @mcplslg123 mention points, please accept my apology, since i asked @mcplslg123 how to check that but he not reply anything so i skip it & more focused on your points,
anyways i'll check & keep you posted,
Thanks.

the same problem, laptop not charging and it wouldn't turn on on battery + notification about operational temperature. Without battery it worked normally.

Got it, Thanks Mark for this info, hope i can fixed mine as well.
Thanks.

Dear dycc,
Below are results,
jbat1: pin1 and 2 ohm value (battery and charger disconnected , black probe of multimeter on ground and red probe on pin 1 and 2) = both pin have 1 result

jbat1: pin1 and 2 diode mode value (battery and charger disconnected , black probe of multimeter on ground and red probe on pin 1 and 2) = both pin have 1 result

jbat1: pin1 and 2 voltages (battery and adapter connected) = 1.8V
Thanks.

Re: Dell Inspiron 17R 7720 "Your Battery is Temporarily Disabled", Battery LED Flashi

if 1 mean infinite on your multimeter , you got no short at +VCHGR . not the same issue as ma_ko
