Megatouch Force Boot problems

<< < (5/10) > >>

lilshawn:
this is not a harddrive issue at all.

this is a board level issue.

computers only need 3 things to boot at all. power, memory, and a CPU.

take a board out of it's packaging, slap a CPU in it and power it up?...won't work. the BIOS needs RAM to load the boot routine into.
slap some ram in a board and power it up? ...won't work. the CPU needs to do the commands of the BIOS to actually boot.

but all 3? sure it complains there is no boot device. sure all you can do is press a button to retry or go into the bios and look around...but fundamentally, it works.

freezing or becoming non-resposive IN the bios is a dead giveaway. a computer can hang before getting to the bios because it is having trouble detecting a harddrive but 9 times out of 10 computers just give up and assume there is no drive and eventually go to the bios even after a 30 second timeout wait for the drive to become available. the computer will still work properly.

while i wouldn't completely rule out a sketchy keyboard connection causing what appears to be a freeze up, it's highly unlikely. like, very highly unlikely.

machine was shipped...something came loose....power, CPU, or RAM.

besides, these machines use a laptop harddrive that park the heads OFF the surface of the platter when shut off. damage caused by moving it while powered off is nearly impossible...if y'all don't believe me i happen to have a dead sample megatouch harddrive right here...



as you can see, the heads are actually "sledded" off the platters when parked. the heads are sledded back on the surface when powered back on.

besides...did you even watch the videos OP posted???

TalkingHeadsFan:
So I took everyone's advice and reseated the RAM again (tried it once before, but it can't hurt). Nothing.
There are 2 spots on the boards for batteries, but one is missing (on the smaller board). There are no loose batteries inside the box/machine. What does this battery do?

The Fan right on top of the celeron processor does NOT spin.

I have one other ps2 keyboard I can try just to rule out the keyboard thing

The CPU has probably been overheated if the fan is not turning. i believe this is your issue.

the battery holder you see is where the software security key goes. (well can go) you can change some jumpers on the IO board and take the key off the remote board for the monitor and move it to the IO board. it's just a convenience thing for to use the IO board with several different machines.

those caps look replaced so they should be okay. the original ones are green.

the original CPU is an Intel Celeron (commonly called a celeron II) i belive 600 mhz? and i believe socket 370. (going from memory here i don't have one in front of me) but basically any socket 370 celeron or even a PIII would work. (albeit run pretty hot)

EDIT: is the fan plugged into the board at all? or is it siezed up? can you turn it by hand?

orizzle:
Almost guaranteed it's heat. I had to replace the CPU fan on an old maxx cabinet. It had so much crud in it, the fan physically would not turn (even when I pushed it with my finger). Make sure it's plugged in.  Otherwise, you can get a replacement fan pretty cheaply on eBay or a parts store.

mahkeymike:
As i suspected, fan is not spinning, hense why i said its probably locking up from overheating cpu. At this point you need to remove the board from the system and replace the fan first and hope that new thermal paste and new fan solves the over heating problem. While the motherboard is out, go over every cap and see if any are bulging. If you cant tackle a cap replacement, myself and other members are more then  capable of replacing them for you. Just stay away from that rip off D-bag Dave. I wont mention his real name but others here know who he is.
