Re: Satellite C55-A-142 Laptop boots only without battery
Update!
Replacement battery was faulty. Ordered a new one and everything works fine.
Had to uninstall battery controller modules from Windows in device manager.
It reinstalled itself and recognized the battery instantly.
Thanks for all the help.

HP Probook G3 low power light, does start sometimes
Hello! I have a Probook G3 in my hands.
It will boot up a few times but then it will turn off and not boot up for a while anymore. When it's not starting the power button is illuminated very lightly, so it looks dimmed. Light next to charging port is not working.
BIOS was updated, RAMs are okay. Not sure what to do anymore.

Battery is charged. Orange battery light is blinking on the laptop. When I remove the battery from the slot, the power on light will light up for like 0.2secs. Just a tiny blink.
Voltage is present all over the board with battery.Last edited by doboka98; 10-28-2023, 02:11 AM.Leave a comment:

Thank you for the responses.
Battery mosfet with DC in (without battery): 3.11 on the source and gate. 19.19 on drain.
Battery mosfet with battery: 10.8 on source and drain, 16.9 on gate.
DC in mosfets with DC in(without battery): 19.3 on source and drain, 24.7 on gate.
Resistance readings:
Battery mosf:
gate to source: 0.39 mOhm
gate to drain: rising to infinite
source to drain: rising to infinite.Last edited by doboka98; 10-28-2023, 02:03 AM.Leave a comment:

Thank you for helping.
I have checked all 3 mosfets and all of them have resistance between everything. Resistances are well above kOhms.
I guess the DC in mosfets should be OK theoretically too because without the battery the laptop works fine. This only happens when I plug in the battery.Leave a comment:

Satellite C55-A-142 Laptop boots only without battery
Hello! I am fixing a Toshiba Satellite C55-A-142 (model no PSCG8E).
It came with an old battery. Laptop was rebooting every 5 sec with black screen, not even entering BIOS. If battery was removed it worked perfectly only on charger. I thought it's a shorted battery so I ordered a new one.
Now with the new one it wont even reboot, but the red battery light is blinking on the laptop. Pressing the power button does nothing. Laptop still works with battery removed.
So to summarize:
1. there is no short
2. Laptop starts only with battery disconnected.... -
