If you don't have the manual handy get it here:
There is troubleshooting info in it.
I didn't notice any mention of the reset contact or switch you have mentioned.
- power button switches are usually very reliable and very unlikely to fail. However, sometimes the button that presses on the switch can become stuck in the on position - if it is stuck in that position the mboard cannot boot - make sure it isn't stuck.
- if certain keys are stuck in the down position on the keyboard the computer may not boot - make sure none are stuck.
- has this laptop been exposed to a liquid spill or rain since it last worked properly?
- have you recently flashed the bios on this computer and since the next attempt to boot this computer has never booted since?
You are taking a big risk when you flash your bios - if the flash fails, and/or the flash chip physically fails while flashing (this is COMMON - these cheap flash chips can only be flashed an unpredictable small number of times), you will have a mboard that will not boot.
- have you recently installed ram that wasn't installed in this computer before, and since then the computer will not boot?
Ram that works in another mboard , or any ram you buy or have lying around, may not work properly, or sometimes, not at all - even if it physically fits and is the right overall type (e.g. SDram, DDR, DDR2, etc.; PCxxxx, xxx mhz) for your mboard. In the worst cases of incompatibilty your mboard WILL NOT BOOT with it installed, and the mboard may not even beep - the ram has to be compatible with the mboard and it's chipset.
See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
Correction to that:
If you still have the old ram, remove the new ram, install the old ram, and see if the computer will then boot. You must remove the main battery and AC adapter when you do that.
- some bioses support running a CD or other optical drive without you having to boot the computer. As far as playing standard audio CDs or possibly other audio CD formats supported by the drive itself, the drive has all it needs to do that except power and connections to speakers. It takes very little power for it to run, so it may work fine even if the main battery doesn't have enough "poop" to boot the computer.
- how old is the main battery? If it's more than about two years old, it may be no longer capable of being charged up enough to boot the computer, or it may be just plain defective.
- are you sure the AC adapter is working and is capable of charging the main battery? Most laptops will not boot when just the AC adapter is connected, and the main battery must be capable of being charged to at least a minimal level and be charged to at least that level in order for the AC adapter to work to help boot the computer.
- Is it possible this laptop has experienced being dropped or other physical jolts since it last worked? If so, or in any case, see the manual, and make sure the main batterry and hard drive and ram are still installed properly. You must remove the main battery and AC adapter when you check the hard drive and ram connections.
If none of the above helps, there is no way of getting the computer to boot if pressing the power button doesn't result in anything happening. Take it to a local place that is authorized to service Clevo laptops and have them diagnose it.
Or you could look on the Clevo web site to see if you can find a maintenance manual and try taking it apart and tshooting it yourself, but I saw no such there.
If you search for Clevo on the web, you will find a wikpedia "hit" that mentions Clevos are sold under other brand names - if you can figure out what model is the same as yours, you may be able to dig up a maintenance manual from one of the other brand name's web sites.
