Question about Toshiba Satellite A75-S226 Notebook

No power to LCD, drives after power jack repair

I'm past the repair of the power jack that gave intermittant power to the laptop only when jiggled and then only for moments. I've de-soldered and re-soldered a new power jack; now have power light on at all times and even able to charge the battery. Problem: although there's power to USB ports, the cooling fans run at boot up, nothing appears on LCD; DVD drawer and hard drive don't seem to be receiving power. Removed hard drive, memory and DVD yet no response in the form of beeps or messages on LCD.

    Didn't think it was the mobo because the unit fired up okay prior to repair...except for conking out w/the loose DC jack. Anyway,I may have shorted something but don't know how using the techniques I used. Thanks anyway.

Hi and welcome to FixYa,

It would appear that you need to dis-assemble the laptop again and check:

  • if the solder job on the new powerjack covered other solderpoints other than the pins of the jack;
  • for any solder balls, solder splash on some of the other components. This could have been brought about when the jack was de-soldered;
  • loose/mis-aligned connectors;
  • wires/cables kinked or crimped when putting back the brackets/casing.
Pls post back result(s). Good luck and kind regards.

The input on the laptop where i stick the charger inn isn't working, what do i do?


DC Jack diagnosis:
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop
