Wont boot up
usually a machine that refuses/ gets gobby on boot up has either a config error or hardware fault. Now the first thing i tend to do is whip out that hard drive (carefully though as the thing is fairly fragile) and plug it into a 2.5" enclosure and stick it into a PC's USB port. If the drive spins up and doesnt make any funny noises like whining, screetching, knocking, thumping or tapping noises, then its pretty okish.
Ok so your drive is ok then is it? good i thought so. Now we mov on.
Go on my friend, you can do it, you can clear that stubborn CMOS/ BIOS, and do this by taking out the battery.....yes i did say battery, and i meant the CR2032 watch type battery that is on the motherboard. this will certainly mean disassembling the machine to get at that round metal button shaped cell battery thats attached to the motherboard by a sprung retaining clip. JUST A WORD OF WARNING WITH THIS THOUGH....ALWAYS WEAR A GROUNDING STRAP AND REMOVE THE MAIN POWER SUPPLY BATTERY AND SUPPLY CORD FROM THE LAPTOP/ DEVICE BEFORE PROCEEDING. always stop if you dont feel able to proceed, and never feel afraid to get help from a techhie like myself (we are nice people that will always help). In addition, when you get to that battery, remove it carefully, and replace it with a BRAND NEW ONE in case the one you have either is a dud, or a bit leaky (can happen if you prise it out to hard or incorrectly with that slot head screwdiver/ extraction tool)
once you got that filthy battery out, you clear the CMOS my usually looking for three pins on the motherboard that may say either CLRCMOS, CLCMOS CMOS, CLRBIOS, CLBIOS, CMOSRST, RSTCMOS..... move the jumper to the clear position for 10-20 seconds, then put the jumper back in its original position or you will find you will be a lil stuck when you put the machine together and it dont work.
once you have done that, put the new CR2032 battery or replacement CMOS battery in, then rebuild your machine.
then go into your BIOS when you start the machine, either F8, F10, DEL, F2 or F12, and enable the most stable settings, and correctly adjust date/ time. then to exit you press F10 or save and exit. and then VOILA, YA DONE.
if this doesnt boot up now, then i think so you may have either a problem with operating system that needs re-installing, or you have a hardware fault elsewhere in the system. Anyting like a dud flop drive or a insulent optical drive can do this. even more so if your boot sequence is wrong, (this should be set to Hard drive, then CD/ DVD then flop, then LAN as default.
if no fault with operating system or peripheral drives, then your fault is within the motherboard layout (deceased CMOS/ BIOS or other critical component). CMOS/ BIOSes can be changed, but this requires extensive electronics knowledge and being very competent with specialist tools such as soldering irons and IC (integrated circuit) extraction tools. All of which if used incorrectly can cause damage to you and your system, so please be careful.
can always try a firmware/ BIOS/ CMOS update, and do this by going to the manufacturers site and download the tool that will flash your BIOS, but ALWAYS READ THE README FILE and NEVER EVER FLASH YOUR BIOS WITH THE WRONG TOOL, YOU CAN AND ARE LIKELY TO KILL OFF YOUR BIOS/ CMOS (they dont usually recover when this happens as they forget their original identity and the motherboard literally "goes insane" beyond repair, unless you extract the IC chip and replace this with one of the exact type)
Anyway, good luck, and i hope this helps you, yours sincerely
if you need any instructions on how to disassemble your machine, and the tools required forthis, then please do ask me, im here to help, i also have the guides on how to re-install and configure your machine
