Hey, I bought a broken second hand laptop for parts to fix my computer, and once I had finished switching the parts, I thought I would try and boot the broken computer. To my surprise it booted flawlessly into my older windows 64bit hard drive. However, despite brilliant performance, when it is turned off, you cannot turn in back on immediately. If you try to so so then the power fails before even reaching the splash screen for HP. By waiting a mere 30 seconds, it boots perfectly again. I waited ten minutes and booted into the BIOS and the reset the settings, and did a memory test which were both successful and fine. And then to my surprise the power failed again. It appears the power fails anywhere before windows has booted if not left for long enough between boots. Any ideas would be greatly appreciated. And sorry for the long winded thread - just thought I would be precise Specifications: AMD Turion X2 2.2Ghz RM-74 ATi Mobility Radeon HD 4530 Motherboard is the Quanta 3060 assuming it is the same as my other laptop. Harddrive is 80gb 5400rpm. 1Gb DDR2 Ram (Hynix.) These are only rough specifications since I don't know the laptop too well. Thanks, Will.
