Hi need help asap.
I opened my acer desk top box to clean dust out and now has warning chassis open.
I cant access the bios or anything else. Does someone have a suggestion????
Panicking
When you open the computer case, a switch is tripped and after the case has been closed and the computer boots up, you get this chassis intruded message. To clear this message go to the BIOS configuration and then to the chassis intruder detect and then Reset this setting.
When the chassis is open but with no seat/carrycot/car seat on, it will move like it is not locked properly, this is normal. When you place a component on top, this will then lock the chassis completely.
First remove the seat or carrycot/car seat if this is on the chassis. Then, stand to the left of the chassis. Push down the button on the handle which lowers the handle bar height with your right hand. With your left hand, take a hold of the black cuff on the side of the chassis (this should be about waist height). In one movement, you need to pull the left hand up, whilst pushing down your right hand, this needs to be done at the same time, and with some force.
When the chassis is lowered toward the floor, this will click shut. To open the chassis, there is a small metal arm on the left hand side of the chassis with a red cover on (this is quite little) you need to lift this button upwards (towards you) and the chassis will open.
Stand behind the chassis with the handle bar nearest to you.
Bend down (leaving the chassis on the floor - don't try an elevate it at all) hold the handle, push the small white button in on your left hand, once depressed pull both triggers (one either side), this will release the handle.
DONT try and open the chassis just yet!
Lift the handle up and stand upright.
In front of you, you will see two parallel axles (nearly touching the floor) place your foot onto the BOTTOM axle and gently push downwards and then kick it outward away from you.
This should open the chassis.
Once the chassis is open, it will appear to be unstable, this will STOP once the seat OR carrycot are clicked onto the chassis.
I hope that all made sense and helps you.
Faling that, I would suggest that you perhaps contact Bugaboo.com for some advice as this is extremely hard to convey in text - Good Luck!
Chasis intruder is a warning that your CPU has been opened by someone it is normally used to warn you against unautorized BIOS or SYSTEM PASSWORD removal There is a switch in your casing that detects this.
Leave this setting to enabled (recomemded)
Thanx and i hope this info is helpfull Please dont forget to rate this solution
You have to disable the chassis intrusion alarm by going into the BIOS as the machine first starts up, either by pressing Esc or Del, in the BIOS you can then disable the alarm.
clear your bios, close very good your case, open bios disable chasisis open detected fro yes to no, (or in some model from enable to disable ) change saves exit booting and good work.
I'm not familiar with that particulat model, but I'd guess the motherboard has a chassis switch connector, and senses the chassis be open. Could be because:
- chassis open (close it),
- switch defect (as a workaround, you could short-circuit it, or just unplug it - whichever solution works for you).
As another workaround, you can probably disable this switch in BIOS.
