I have been experiencing what I believe are heat related problems with my Laser 128. Here is some background: The Laser128 comes with built in RGB,Modem,Parallel Printer,Serial printer,mouse,and drive cards. It has one internal drive, the whole thing in a box similar to the //c. I have a CPM card in slot 5 (located on the left side sticking out of the box. I am using an RGB montior, 1 external drive, a parallel printer, and a modem. Due to the frequency of use I have basically left it on for the better part of the last year (it is 2 years old) in order to reduce wear from turning it on frequently. Recently (last 2 weeks) it has started dieing on me: Program stops execution and reboot just result in a garbaged screen with not attempt to access the disk. Turning it off and back on does the same. After being off till the case was cool it would re-boot. This started happening here when our temperatures started getting high (no air-conditioning). However they have been this high numerous times before with no problem. The one difference I can think of is that the humidity was the lowest it's ever been during that amount of heat. (It is usually VERY humid here in the south). In retaliation I have had a fairly good fan blowing across it, but this hasn't really helped. What has helped is the humidity going back up, it is still doing it but not nearly so quickly. Any ideas on what is going wrong? How much it is going to cost to fix? Might I try dis-assembling the case so that I can get more air flow? +=======================================================================+ |Scott Hinckley - OCS User Assistant AKA - Galaxy's End | |Georgia Insitute of Technology, Atlanta Georgia, 30332 | |uucp: ...!gatech!pyr!ccasths | |ARPA: ccasths@pyr.gatech.edu | +=======================================================================+

Here are a couple of suggestions to help ventilate your laser: - make sure the ventilation slots are not covered or blocked - use the handle to prop the computer up to provide airflow underneath - don't set the power brick near the computer - open the metal 'door' (for ROM chip changes) underneath the computer - turn the computer off at night (leaving it on all day is good for preventing wear, but it should be turned off if it won't be used for several hours) - locate the computer in a cool area of the house (such as the basement) - do not put the monitor directly above the computer All of this is pretty much common sense, but we all know how uncommon that can be. Perhaps I've suggested something you overlooked. Good luck. Overheating may have already done some permanent damage to your chips. If problems continue, see your dealer (don't you hate those 3 words??).
