Did you run a bios updateand has an anti virus programme installed? If you did the bios is corrupt and stopping the system from running.
I would remove the RAM and Hard drive. Power up without the battery and look for error messages on the screen. Ensure the RAM is correct and place one strip in at a time.

SOURCE: toshiba satellite A60 no boot

We can only assume that because the cd drive operates then the motherboard is operating in part, although, the southbridge chip may be damaged, as the northbridge works memory etc. Maybe it is that the processor is fried as there is no fan and the system then shuts down. Toshiba are probably half way there with the answer, unless; they investigated further and decided it was not the processor but the motherboard.

SOURCE: Will not boot up

this is motherboard hardware issue
1) first all you need take out all devices like HDD DVD, wireless card then try turn it on if noting yet
2) change RAM stick that you have done
3) check DC PWM standby status, like 3V/5V/1.8V which should be appear before power on.
if no 3V/5V DC output, check this PWM circuite like MOSFET or PWM chip.
if you find 3V/5V, so need check 1.8V DC output and 1.2V that chip fail also cause nothing turn on.
all steps need diagram check where the chips and componenets on your board.
hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question

I have a Toshiba laptop model# C655-S5501 with a bad keyboard (Gator Aid!). I can't find an exact model # match through Amazon. Will the "Eathtek NEW Keyboard For TOSHIBA SATELLITE C655-S5128 C655


Check eBay. I've been working on computers for years and order ALL of my replacement keyboards through eBay. I just found 9 of them after entering your model number; about $16 with free shipping. Sarawill82 hit the nail on the head for the replacement; you tube is your friend if you're doing it yourself. If it doesn't have your exact laptop, look at other videos. It will give you an idea what you need to look for to replace the keyboard.

It beats paying a computer store a $45+ bench fee, and it will only take you about 15 minutes as a novice.

Don't try to clean it; you could cause more extensive damage than just replacing the keyboard.

Toshiba Laptop Satellite C655 will not power up


Take out the battery and only hook up the AC Adapter into a normal working outlet. Push the power button and if it turns on then you know the battery is bad. If you still dont get the laptop to turn on then either you have a bad AC Adapter or the motherboard is bad and would need to be replaced.

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:

Toshiba Satellite C655-S5082. Won't power on. Worked fine last night. Today it won't turn on. Plug it it and no power light. With power cord plugged in when I push the power button the light for...


Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.

Fpi need a webcam for my laptop c655 toshiba which one will i buy that will work with it


Hello fpat2479,

The C655 does not have a webcam built into its LCD bezel (case). But there are many webcams that should work on the C655. The TigerDirect.com website offers many webcams in a variety of price ranges. Most of these should work ok on the Toshiba C655:

If this solution is helpful please click a thumbs-up rating.

Have a great day,
