Toshiba Satellite - Locks up when plugged in

Re: Toshiba Satellite - Locks up when plugged in

Im still trying to make sense of this. While the laptop is being powered from the charger only, what happens when you insert the battery?

Only with the charger work ok, when i but the battery while i have the charger and the system runing after a few sec will shutdown.

The battery is not charging and also i get a message that say i must replace it.
I will try with a new battery

Re: Toshiba Satellite - Locks up when plugged in

Hello,
i have the same prob A300. but my Q is if i can remove the tokin cap with heat gun and thermo laser gun???

Re: Toshiba Satellite - Locks up when plugged in

yes, you are likely to be able to and make a mess as well. It is difficult to apply heat to where it is needed without the part melting an falling to pieces. It is much safer to gouge it off the PCB. It is not necessary to scratch the crap out of the PCB in the process.

Hi tnx 4 the help.
but i dont care if the tokin will melt of fall in to pieces cuz its dead already ;-)

P.S
I forgot to ask if i can do it without removing things from the MB???

I normally don't. You will risk melting the solder under the CPU socket. Also, leaving the CPU and heatsink attached might draw away a lot of heat.
Causing extra damage to the mainboard is the main thing to worry about.

Re: Toshiba Satellite - Locks up when plugged in

So i havve to remove the CPU even if i dont use heat gun? But after i remove the tokin i will need to apply heat anyway to solder the new caps and the CPU will drew heat also so whats the different?

No need to remove the CPU if you are going to gouge the capacitor off. A good soldering iron with a large tip is all that is needed to fit the replacements. I use a Hakko 936A clone with a K tip. A soldering iron heats a small area.

There is lots more detail in this thread. Did you see the other post that I mentioned earlier?

Why did u add solder between the caps?

[rievax_60]

Re: Toshiba Satellite - Locks up when plugged in

Why did u add solder between the caps?

To connect their (-) ends to the ground print. The green coating is called Solder Mask which needs to be scraped away to expose the underlying copper print so that is can be soldered to. Excessive scraping will ruin the mainboard.
You need to read more of this thread. You forgot to answer my previous question. It is sometimes difficult to know what is being ignored.

But the outer line are + and the inner lines are - so why we need to add (-)?
I did saw ur post it was helpful 4 me tnx.

The (-) tabs under the capacitors do not overlap the original (-) solder pads/stripes. Other members solder their replacement capacitors at an angle so that the capacitor tabs can be soldered directly to the original pads.

So if my caps (-) touchs the (-) terminal i dont need to do what u did,right?

That's right, if you can solder it properly. You have no electronics experience?
What equipment do you have?

Dont do that if you want your laptop to work again. I have explained a safe method. Read more of this thread to see other members' experiences, good and bad, and avoid the unnecessary scratching.
Send us a photo of your iron clearly showing the tip.

Ok tnx 4 the help😃
I ordered hakko tips, all of them😃.

Heres my soldering iron HAKKO PRESTO 981

I didnt even know that iron existed. It would take some practice to get the heat right. I use a K tip or large chisel tip. The rest depends on your soldering skill.
Check the resistance of the CPU between the (+) and (-) pads before you start. Then check it after you have fitted the new capacitors to be certain there is no short circuit caused by the soldering.
