86.0 Bateri CMOS di komputer

ASUS motherboard - bahagian bawah kiri terdapat bateri coin cell CMOS backup (jenis CR 2032)

Untuk makluman, di dalam setiap komputer PC atau laptop ada bateri back-up atau bateri CMOS.  Apabila komputer diguna selama beberapa tahun, tarikh dan masa dipaparan komputer akan lari i.e. tidak tally dengan program.  Setiap kali dibuka komputer, tarikh/masa akan tidak tepat (i.e. ia tak update), kemudian kita perbetulkan tetapi dibuka ia akan lari semula. Apabila perkara seperti ini berlaku, bermakna bateri CMOS sudah kehabisan power dan perlu ditukar. Kalau bawa ke kedai, ia akan tukar bateri baru dan dicaj RM30.00 atau RM50.00 padahal harga bateri kecil itu cuma RM5.00 boleh dibeli di kedai runcit jenis CR 2032 atau lihat kod pada bateri asal itu. Perkara ini mudah dan boleh dibuat sendiri.  Saya telah mencuba dan ternyata berkesan, tiada masalah. Baca dulu cara2 menukar bateri tersebut. Apabila selesai tukar bateri baru, reset CMOS atau BIOS, boleh rujuk website:  http://www.computerhope.com/issues/ch000976.htm    Selamat mencuba.

How to replace the CMOS battery. 

Cause: Like any battery the computer CMOS battery can fail or lose its charge.

Solution:

If your computer is losing its time or date settings, or you are receiving a message CMOS Read Error, CMOS checksum error, or CMOS Battery Failure, first try leaving the computer on for 24-hours. In some cases this can charge the battery and resolve your issue. This often resolves CMOS battery related issues when a computer has been left off for several months. If this does not resolve your issue follow the below steps.

Locate your CMOS battery

Caution: When inside your computer make sure you're aware of ESD (ElectroStatic Discharge, is one of the few things an individual can do to damage or destroy his or her computer or hardware components. Much like the shock you receive when rubbing your feet on the carpet and touching something metal, ESD can occur when working in your computer and will cause components you touch to no longer work properly. ESD can occur without the user feeling a shock and will only occur while working on the inside of the computer or handling an expansion card.) and all it's potential dangers. The best method of preventing ESD is to use an ESD wrist strap or use a grounding mat or table.

However, because most users do not have access to such items, we have included the below steps to help reduce the chances of ESD as much as possible.

Zero Potential - Most importantly, make sure you and the computer are at Zero Potential by continuously touching an un-painted metal surface of the chassis or the computer power supply case.

Standing - It is also very important that you are standing at all times when working on the computer. Setting on a chair can generate more electrostatic.

Cords - Make sure everything is removed from the back of the computer (power cord, mouse, keyboard, etc).

Clothes - Make sure not to wear any clothing that conducts a lot of Electrical Charge, such as a wool sweater.

Weather - Electrical storms can increase the ESD risk; unless absolutely necessary, try not to work on a computer during an electrical storm.

Accessories - To help reduce ESD and help prevent other problem, it is also a good idea to remove all jewelry.
