I have (or rather my GF has) a broken laptop. Toshiba L300D-10Q (Model PSLC0E-00C00DEN) It just cut out one day and won't come back to life. It's two years old, out of warranty. I've checked that there is power to the motherboard but beyond that it's a bit beyond my level of ability. Replacement motherboards are on eBay for about £100 and up. This is for a second hand tested one. Before I get one: 1) Is there anything else worth checking? 2) Is there any reason not to swap the motherboard in the hope that it will all work? 3) Is it likely to be worth it in view of the cost of a new Laptop? (Don't know the spec, it's got 1GB of Ram....) By way of comparison, my Dell 1300 though tired is still going after 4 1/2 years although I have had to take it apart and solder things etc. a few times.
