Question about Toshiba Satellite U305-S7448 Notebook

1 Answer

I bought a new charger for my Toshiba satellite u305 series which had capacity of 19v and 3.95A. but amazingly it spoiled my machine. immediately after inserting the charger to my laptop instead of indicating it is inserted on the power,it showed nothing and immediately it started producing a ticking sound coming from the motherboard. i have tried using other chargers that used to work before but its just producing a ticking sound. it is not indicating the blue light for power nor the the one for battery. its just not showing anything. it cannot boot. i have tested my RAM and Harddisk if they are okay and it turns out they are 100% okay. i have tried flashing BIOS but its all in vain it is still producing the ticking sound on the motherboard.i have checked using my naked eyes that the capacitors in the motherboard have not yet blown.they are intact.im now confused what could be the problem??im glad that i found you and i have confidence that you are going to help me..thanks in advance.

If the replacement charger was not exactly equivalent, including polarity, you probably toasted your machine.

SOURCE: Toshiba Satellite will not run when using the battery

it really sounds like a hardware problem for which probably your motherboard may have to be replaced but i was checking on the website for bios updates and I noticed the newer bios is not v3.30 but version 4.40. posted on
08-04-2008 BIOS
I think it's probably worth it to give it a shot whith this new Bios and see where it would take you

make sure to back your data and that your power is constant while you're doing the bios flashing!

download your bios update from here:

SOURCE: Toshiba Satellite A135-S4527 Charger problem

Get another laptop.

The A135 is a lemon.

Problem is either with the dc jack on the board or more than likely the motherboard is damaged.

I've repaired a number of A135's and 95% of the time motherboard had to be replaced.

Sorry for the bad news, but I hope this helps.

SOURCE: My Toshiba Satellite Pro A200 works fine if I use

It sounds like the connector from the A/C adapter to the motherboard is loose or the inside of the adapter plug that attaches to the motherboard is defective.

SOURCE: Laptop Toshiba Satellite A200 Model No. PSAF6A-02C01N fail boot

Try removing / swapping / reseating the memory.

Try booting with one stick only, if the top slot doesn't work, try booting the bottom slot. Try both sticks.

Let me know what happens.

SOURCE: toshiba a105, wont power up, clicking sound

I seem to have the same problem. I have an a105-4134. Ive had since June of 2006 and ive kept it clean and have replaced several components throughout its life.

I was working on it few days ago until it just shut off. Confused, I press the power button thinking maybe the power adapter wasn't plugged all the way in and the battery depleted and it shut off. So now the computer will now power on. It lights up but shuts off within 1 second. Keeps doing this over and over.

My first thought was the dc jack as ive read it is common to be faulty after long use. I ordered a new one and unfortunately it was not the culprit. I then suspected the cheap aftermarket power adapter which replaced the dead oem power adapter. Bought a new one and experienced the exact same symptoms yet again.

Now I'm digging deep removing all components one by one. With each one I remove, I gain a few seconds of time that it will stay on before shutting off on its own. I powered it on with only the motherboard and cpu and it does the same thing.

From the original problem in this post, the cpu and motherboard were swapped out and same symptoms still occurred. This being the case, the only component left undiagnosed is the power board itself.

This is where I noticed that the computer will power up and run on battery power. The adapter plugged in will charge the battery but not power the computer while running. With this discovery it means that it cannot be any of the main components causing the problem.

Back to the power board, an obvious problem area seeing how this is tied in with power components. From the looks of it, it seems like a simple switch board but i may be wrong. My next step is to order a new power board. I will let you all know how it turns out.

Power port not working on toshiba c655


You had better replace your laptop charger. Even if you go to repair it, it will cost you the same price of getting a new charger. So it is wise to purchase a new one. Here are two for your reference:

$9.99 for Replacement Toshiba Satellite C655 AC Adapter 65Watt 19V 3.42A

$12.90 for Replacement Toshiba Satellite C655 AC Adapter 75Watt 19V 3.95A

Toshiba satellite L305-s5955 will not power up


If there is no power light and it can't charge your laptop, it is likely that the charger is dead. You need a new laptop charger. So try a new adapter to confirm the real issue.

There are two kinds of ac adapters for your toshiba l305-s5955

Toshiba Satellite L305 AC Adapter 75Watt 19V 3.95A

Toshiba Satellite L305 AC Adapter 90Watt 19V 4.74A

You should choose the right charger depending on your original adapter's specification. If the original one need 90w, you won't buy 75w that will bring damage to your laptop. If it needs 75w you can use 90w too.
