I bought this notebook (Toshiba Satellite L655D S5055) in August 2010 as my old notebook had fallen from my car's roof while driving (long story) and it was the cheapest one I could find at OfficeMax, on sale at the time for $399.99. It served me adequately, with a few problems (such as the infamous loose DC jack connection, which never became so loose as to not work), until December 27, 2011. I left the laptop on my bed, on, and ran to Wal-Mart for a short errand that night. When I came back, it had suspended to disk (or appeared so). Pressing keys did not turn it back on, so I thought that it had crashed while suspending, as it had before a few times. I powered it off and then back on, but the screen did not turn on. I powered it off a second time, and then turned it back on, and:
- The power light was on (as usual), but not the battery light, even when I was running it off battery power. However, when I attached the charger, the charge light came on
- The hard drive did not spin, nor did the hard drive light come on (at least for more than a split-second)
- The screen remained dark
- The fan turned on, and ran continuously
- It did not make any beeps as usual when booting
- The DVD-RW drive seems to work as usual (spins, seeks, etc.)
It has done this whenever I tried to start it up.
Is my laptop now brain dead? Or could it be something simpler? Please tell me.
The screen staying dark and lack of the usual single beep of a successful POST (power on self test) is hinting at some major problem.
But I can't pinpoint any specific part or think of anyway to troubleshoot the problem.
Disk fragmentation is a natural occurrence and is constantly accumulating each and every time you use your computer. In fact, the more you use your PC, the more it builds-up fragmentation and over time your PC is liable to experience random crashes, freeze-ups and eventually the inability to boot up at all.
