Re: Constant Rebooting with Toshiba L350 Laptop using Power Cable
Thanks you for your reply.
I was talking about the solder I added when making a rubbish job of soldering the caps. I would like to clean off the solder so it is a clean pcb the same as it was before I started to solder.
Thanks for the confimation on the two nagative strips being joined....

Re: Constant Rebooting with Toshiba L350 Laptop using Power Cable
Thank you for your reply. Sorry about the picture but I only have a old 3mp camera.
I might have some short circuits. I will remove the caps and try again.
I would like to know please what is the best way to remove the old solder from the board? I have tried solder wick but it just gets stuck to the board. If I can clean up the old solder I will try again to add the caps but first I must remove the old solder befor I try again to iliminate any short circuits problems.
Also this...Last edited by noob2laptops-uk; 08-02-2015, 07:55 AM.Leave a comment:

Re: Constant Rebooting with Toshiba L350 Laptop using Power Cable
Houston we have a problem!
Ok...
I decided to 'have a go' and it all started ok. It took a long time to get the nec tokin cap off but it came of with loads of scraping.
I have soldered on the caps (see attatchment image)
But...
When I switch on the laptop there is power but there is not monitor working and no hard drive working. I dont know if there is any bios as the monitor is not working. All cables are back where they need to go....Last edited by noob2laptops-uk; 08-02-2015, 05:28 AM.Leave a comment:

Re: Constant Rebooting with Toshiba L350 Laptop using Power Cable
Need a little extra advice before I start to replace my nec tokin chip on the toshiba laptop.
Do I need to add fresh solder (or tin) the pos and neg pads on the pcb first before adding the smd's?
ThanksLeave a comment:

Re: Constant Rebooting with Toshiba L350 Laptop using Power Cable
Ok ....
I have taken the advice from the members of this forum and I have managed to get everything I require including a 60w soldering iron to have ago at fixing my laptops nec tokin chip and replacing it with 4 330 smd's
I would like to know please after I have removed the old faulty nec tokin chip and cleaned up the middle between the posative and negative do I need to add a fresh strip of solder to those two strips either side?
ThanksLeave a comment:

Re: Constant Rebooting with Toshiba L350 Laptop using Power Cable
So the 40w would be better? Or would that be a bit of overkill as I am a 'beginner'Leave a comment:

Re: Constant Rebooting with Toshiba L350 Laptop using Power Cable
If I bought a soldering iron what would be the best? A 30w or 40w? I will be using it for soldering the caps etc.
Thanks in advance

Re: Constant Rebooting with Toshiba L350 Laptop using Power Cable
Just out of interest. How would I remove the 330uF tantalum capacitors from the old boards? Would they need to be old laptop boards? Would I need any special equipment or would a standard soldering iron do the job. Also would they be the correct ESR?
Thanks...Leave a comment:

Thank you for your reply
I have been reading through that post earlier and that is what made me think that it maybe the Tokin chip at fault. I am interested in 'having a go' at fixing it as it would be a learning curve. Ok it works on a battery but I wanted a laptop that worked on mains as I would be using it for longer periods that 2 hours.
What would be the best thing to do? What would the best setup be as a replacement for the Tokin chip? How long would they last...Leave a comment:

Constant Rebooting with Toshiba L350 Laptop using Power Cable
Hello
I have recently purchased a Toshiba Satellite L350-203 PSLD8E-073008EN [url]http://www.toshiba.co.uk/discontinued-products/satellite-l350-203/[/url] off ebay. It works fine when using the battery but when I remove the battery and run it from the mains adapter it constantly reboots after 3-5 mins of use. It is very anoying as I cannot install a fresh operating system unless I use the battery then I only have less than 2 hours of use. I was looking to use my laptop by using the mains power supply but this is not possible. I have disable reboot on windows errors so it shows a blue...Last edited by noob2laptops-uk; 06-05-2015, 03:08 AM. -
