Having had repeat problems with charging on my Lenovo laptop (I dropped it and made the case weak around the usb-style charging socket and when the stick-out plug is knocked it levers up the case and messes up the wiring inside) so I intend to place my laptop on a plywood (or similar) board of size (approx) 42 cm x 32 cm x 0.9 cm and secure the charging plug to the board. So (1) Is plywood sold here? (2) Do they sell 'offcuts'? (3) Is there a more suitable wood for my purpose? 4) Where to buy in or near Dumaguete downtown? Btw, I hate the Lenovo charging plug as it sticks out of the side and is easily knocked (esp. as I use my laptop whilst in an armchair); I have been told that Lenovo is using that charging system on all their laptops now and, on that basis, I would suggest avoiding that make.
