A short, practical checklist to follow after the initial posts from and . These steps focus on safe isolation of the fault, how to identify the correct replacement adapter or when a board-level repair is likely.

  • Record the laptop model and any service/part numbers on the underside sticker. That information is the primary reference for matching parts and replacements.
  • Note any markings on the adapter label (output voltage, current rating and connector/part number). Replacements must use the same voltage and polarity; the current rating can be equal or higher.
  • If a compatible spare adapter is available, try it to see whether the laptop powers up. A successful test points to the adapter; a failed test points toward the DC jack or internal power circuitry.
  • Visually inspect the DC jack and cable ends for looseness, bent pins, discoloration or melted insulation—these visible signs often indicate an easily fixable fault.
  • When ordering, use the laptop or adapter part number and buy from suppliers that publish specs and allow returns. Prefer items with safety approvals.
  • If a substitute adapter does not restore power, a technician should test the input jack, board fuses and power rails; mains-side work and adapter internals are hazardous and should be handled by qualified service personnel.

Having model and part numbers ready before contacting suppliers or repair shops shortens diagnosis and avoids incorrect purchases.

Whatever you do, don't take it to PcWorld. They are useless and expensive. If you have a digital volt meter then you can test the power supply yourself. Touch the red probe to the middle pin and the black to the outer barrel of the power plug with the meter set to 20 volts d.c. and you should see about 19 volts. If you don't get any reading then your power supply is dead.
If the power supply is dead, get an original Toshiba one as it will have all kinds of built in protection. Don't get one of the cheapie ones off of eBay. They may look like a bargain, but when they blow and do serious damage to your laptop it will cost a lot more than what you saved on the price of an original one!

Thanks Rik

I dont have a volt thing...and im quite useless with technology. i have just bought a new house and have minimal things ... where should i buy an origional lead from ...? i changed the fuse but that has made no effect bu ti know the battery on the laptop itself never worked and the electrical supply lead woudl get so hot when on...so i am assuming it is the lead ...how much can i expect to pay...maybe the origional one from pc world? il buy it and use it there to make sure it corrects the problem xxhelp?

If the lead got hot then it was internally shorted so it does look like it's the power supply that is at fault. You will find original Toshiba power supplies on eBay. Are you in the UK? If so, I most likely have a power supply for your laptop (I'm a computer engineer with a workshop).
