Repair circuit toshiba satellite c660-15n - Toshiba Computers & Internet

the battery charger circuit is short circuit, therefore need to repair or test the battery is ok

Actually your make and model of satellite was the worst of toshiba's recent production- the estimate was 16-18% have displayed what's called an intermitten i/o failure to the main board. (Input output of processing data to the mother or logic board that processes the overall functioning of the comp~ the brain of the comp). This has plagued Toshiba's production for the last 3-5 years, and 9-18% of units have been affected. The good news is: it's neither a logic board nor electrical failure! And the repair is both easy, a DYI repair for any novice, and super inexpensive (well in the grand scheme of comps). What will fix your laptop is new RAM. Your toshiba can seat up to 8gs and as little as 4g. It uses DDR3 RAM, paired. The ram sits in the main board and over sees the i/o of data, is a main part of the EFI (the firmware interface of your hardware), and is in charge of ensuring the electrical assembly circuit is complete. Cost of parts on Amazon (spring for new RAM) will run you $50-65, the repair is 3 screws, pop out old ram, pop in new, replace panel, screw back in 3 screws. It's the easiest possible repair you can do yourself, even listed in the owners manual. See links below. 1st is your ownwers manual, 2nd is to ifixit.com to your laptops ram replacement guide. I'm an A+ PC repair tech and an ACMT apple repair tech. I rarely recommend DIY, but this is cake. If you boot after and see 3 blinking lights, you didn't put the ram all the way in. good luck! Next time, buy a toshiba TV, but not a laptop.... :) http://www.manualowl.com/m/Toshiba/Satellite-L655-S5150/Manual/281632 http://www.ifixit.com/Guide/Installing+Toshiba+Satellite+M305D-S4829+Memory+%28RAM%29/5424/1

This cannot be fixed any way other than repairing the knob or short circuiting the contacts where the potentiometer used to be (not recommended) as your volume will be on full all the time although you could use windows to software turn it down. because if you are going to do that, it wouldnt be much more work to replace the knob.

This section of Toshiba's web site will allow you to locate a service center.

I hope it's OK to post links to other websites, but I really don't see any other way. Here's everything you're ever gonna want to know about toshiba laptop disassembly (free): www.irisvista.com

It sint the power jack, but rather the Power control circuit. This circuit isnt repaired but replaced. I recommend taking this to an authorised service center or a certified technician of the latter is not easily avilable. If you choose to repair this at your own risk please remember doing so without the necessary knowledge will result in major damages.
