A coworker of mine mentioned his computer wouldn't turn on after he got back from boot camp and it's been sitting since. He said he tried turning it on a while ago and it said something about a battery. (I thought to myself, an easy quick fix...replace the CMOS battery and hand it back over).
Instead I get it here to find out the LCD had a back backlight. I give it back to him and tell him it's time for a new LCD... it can be repaired but I wouldn't do it and it'd probably cost quite a bit to have it done elsewhere... not worth it for an old school dell 15".
About a week later my buddy asked if I wanted 2 Dell LCD's. I said Hell yes. Because I got them for free I gave my coworker a newer Dell 17". I told him to bring his tower back to work so I could bring it home and actually get a chance to look at it. I never got a CMOS warning but the computer was extreeemely slow. I checked the harddrive and it had something like 100MBs left. I called him and asked if he wanted his music backed up and he said no so I went ahead and deleted 20gigs worth of music and that brought the rig back to life BUT after running about 15 minutes the fans would kick into high.
I got around to picking up a can of air and just opened up the case. WOW.
Basically I'm down a couple hours of work, a 5 dollar can of air, a 17" LCD and a few pounds of inhaled dust because I had to resort to physically blowing out the case when I ran out of compressed air. I "like" doing things for people but this was an eye opener... I was scheduled 9 hours last week and 10 hours this coming week. Why in the HELL did I do all this for free?
Never again.
