Living Room / Re: tc1100 tablet pc dies before i've even set it up
« Last post by 4wd on September 02, 2010, 03:11 AM »4wd; that sounds like exactly what has happened. the usb ports had been fine when using a memory stick. and the pop sound happened exactly on making contact between the external dvd drive cable and tablet's usb socket.
the external drive is quite "basic". it's actually just an empty case that you put your own drive inside. the power unit is inside the case - not that there is much to see. i'll upload a photo if you like.-nudone (September 02, 2010, 02:07 AM)
That sounds more like a short in the USB cable, (or interface board inside the external case), or the external had become faulty and was feeding voltage back down the cable - unless your willing to test the USB cable itself or check the USB port on the external for shorts/voltage then I would suggest putting it aside and not using it. Or possibly there's something wrong with either the USB cable 'A' plug or tablet socket that allowed the 5V power to contact either the metal shield or one of the data lines.
Otherwise, if you want to test it I suggest going to Poundland or similar and buying a cheap 4 port USB hub to act as a buffer. Plug the powered external DVD into the hub first, if it doesn't go bang then plug the hub into a PC and see if it is recognised. If it does work, always use the external through the hub in future - just in case.
as for "next time". i think i may just avoid using external DVD drives completely. it has always been the sort of equipment i'd use on other people's computers - if they don't have a DVD drive. so, in one way, i've been very lucky that i've only broken my own machine - i could easily have blown up someone else's computer by the sounds of it. from now on, i'll just use a memory stick.
It could happen to anyone, I've a Sony DRX-S70U-W slimline external DVD that I use all the time, along with a couple of external 2.5" HDDs.
i'll have a look inside the tc1100 and take some photos. it's not like i can hurt anything now...
It'll be interesting to see them and hopefully it will be something simple, (eg. protection diode, fusible link), albeit possibly a pain because it'll most likely be surface mount.
