Laptop Motherboard Failures:
*Also a very high rate of failure over desktop systems*

Reasons: Manufacture design, excessive heat due to lack of adequate cooling, lack of proper use & maintenance by the user. Use a laptop on your bed, couch or even on your laptop blocks the very small cooling vents off on the bottom of laptop, which generates more heat inside of the laptop. The #1 reason for computer hardware failure is heat, the internal hardware/electronics do not like heat,,, another strike against laptops in general.



Internal DC Power Jack Connector: The worst design, very common weak spot on Windows based laptops.

Reasons: The internal DC Power Jack Connector is a very small, very important part on the laptop, break it, and your laptop is out of action once the battery runs out. Normal use, or accidental damaged caused by one to many hard tripped over power cords, a hard yank on the power cord will eventually loosen or break the power connection internally on laptops. Resulting intermittent battery charging, nom power at all by the power adaptor at all, and a “no power on”, dead laptop. The DC Jack is repairable at approx 5, full laptop dis-asembly is required, if the DC Jack has damaged or shorted out the motherboard….. your basically in for a new laptop.

Tips To Help Maintain Prolong The Life Of Your Laptop:

Be gentle, very gentle with your laptop, the electronics and hardware inside are very sensitive and delicate.



Do not sit your laptop on the floor, or chair, or couch, for you are asking for trouble! Do not drop your laptop, do not step on, sit on, or put anything on on top of the laptop. The screen is very delicate!



When closing the laptop, close the screen lid by the middle of the lid OR by both corners. Grabbing it by one of the corners can flex, torque, twist the lid and LCD screen panel inside, breaking, cracking the screen.



Do not use your laptop on a your bed or couch. The material conforms around the laptop bottom suffocating the laptop from cooling properly.



Do not leave your laptop on overnight, remember it does not cool properly to begin with.



Purchase a USB cooling pad for your laptop. This elevates the laptop, and has a USB cooling fan which circulates cool air to the bottom of the laptop, it’s heat source.



Run a disk cleaner, defragment the hard drive periodically and keep it virus free. A virus infected, fragment hard drive has to work much harder, more work means more heat that the hard drive generates.



Do not spill anything on or close by your laptop, this will create major problems also. If you do, turn your laptop upside down, you want to get that liquid away from the inside of the laptop, and DO NOT TURN IT BACK ON. Take it in for service to have the laptop checked.



And last but not least, for your own sanity, and piece of mind, that “so important data” that you were going to back up, that you just have not got around to backing up, that you thought will be there forever and ever on your laptop……………………….. BACK YOUR IMPORTANT DATA UP today, before you regret it!

Tips When Looking For A New Laptop, If you Must:

Look for a laptop that is built sturdy, has some weight, that might take a bump or drop better then others. Do not let the light weight style, theme, the name, or the “bells & whistles” that attract you to the laptop fool you!



If the laptops are on display, and turned on, lift the laptop up, and put your hand on the bottom of the laptop. Does it feel hot just sitting there on there counter at idle speed on the underside, with nothing intensive running? While you are under there, check the cooling vents on the bottom, are they large enough to properly cool down that laptop? Run your hand over the keyboard from left to right, do you feel heat thru the keyboard area………….. if you do move on, you are not interested in that laptop.



Grab the LCD lid, is it so thin does it flexes the screen? Slowly close it by one of the corners, does the lid flex or twist a bit? If it does, move on, your not interested in that laptop either. Last Christmas I was in Walmart here in town, they had 8 laptops turned on, and on display, they were also chain lock to the counter for security. 5 of the 8 laptops they had on the display counter, turned on had cracked screens,,, I don’t think they fell off the counter, I think they cracked from customers moving or closing the lid.



And if you find the right laptop, and they offer an extended warranty, find out what it covers, and take it for the maximum length.

In general, to sum it up here, laptops are VERY delicate machines that are not designed very well to really last. IF you take very good care of it, follow regular maintenance, follow user maintenance practices (keeping it cool), and keep your fingers crossed, it might just last you ok.

Batery Laptop Repair & Flash

Ok Cok.lek.uda,Kang, Mas Bro pertama2 mari kita telaah beberapa Q/A dibawah ini (sorry copas dari tetangga, tapi tidak terselesaikan masalahnya, kini gue coba menyelesaikannya bro...semoga....!!!!)
1. Saya baru pakai 3 bulan/1tahun kok baterai sudah tidak bisa dipakai :
Baterai dipakai BUKAN BERDASARKAN WAKTU (hari, bulan, tahun), tetapi di-DIHITUNG berdasarkan CYCLE CHARGE-DISCHARGE, setiap satu cycle kemampuan berdasarkan kalkulasi BOARD BATTERY akan berkurang, bukan kemampuan cell baterai. Dimana BOARD BATTERY ada batasan minimum kemampuan baterai yang diperbolehkan. Pada umumnya baterai bisa sampai 400-600 cycle. Jadi kalau dalam satu hari melakukan 30 cycle, kurang lebih baterai dalam 10 hari akan drop

2. Baterai saya charge kok tidak penuh2x hanya sampai xx% :
Kenapa tidak penuh2x, karena Current Capacity di BOARD BATTERY tidak sinkron/SAMA dengan perhitungan Arus dan Voltage CELL BATTERY (CELL IMPEDANCE). Ada beberapa type yang bisa di kalibrasi ada yang di LOCK oleh MANUFACTURE BATTERY (Bukan Manufacture laptop).
3. Lampu charge baterai menyala tetapi kalau adaptor di cabut laptop ikut mati / baterai tidak berfungsi normal :
Kondisi ini biasanya karena SAFETY CIRCUIT di BOARD BATTERY sudah rusak, bisa di akibatkan over current (I), over voltage (V) maupun heat atau panas. Dan didalam BOARD BATTERY terdapat safety circuit 3 lapis dan CUKUP CERDAS
4. Baterai saya simpan (tidak dipasang di laptop) setelah beberapa waktu kok tidak bisa dipakai lagi. Karena KATA ORANG kalau baterai mau awet lebih baik dicabut :
Didalam BOARD BATTERY terdapat “self discharge/day” parameter dimana apabila battery tidak dipakai akan mengurangi “Current Capacity” di BOARD BATTERY , dimana ada minimum CURRENT CAPACITY yang di ijinkan oleh BOARD BATTERY. Apabila terlalu rendah maka BOARD BATTERY akan mengaktifkan SAFETY CIRCUIT, alias bunuh diri.
Ok bro kita mulai pecahkan masalah ini,
pada umumnya baterai laptop teridiri dari 6 bagian pokok :

perlu di ingat bahwa dari ke 6 bagian diatas semuanya berpotensi RUSAK, hanya 1 yg berpotensi rusak secara FIRMWARE yaitu pada bagian F.
Nah.....untuk menjawab ke 4 point kerusakan baterai diatas ?, sebelumnya saya mau tanya agan2 semua, apa yg agan2 lakukan jika printer agan error WASTE TANK FULL? (kalau didunia baterai laptop istilahnya CYCLE COUNT) jawabanya pasti SOFTWARE RESETTER. begitu juga baterai laptop .

tidak seperti mereset printer, untuk mereset baterai agan2 membutuhkan sebuah interface yang menghubungkan antara baterai dan komputer yg masih mempunya port LPT1, interfacenya agan2 bisa buat sendiri, tapi untuk yg buta elektro bisa minta bikinin temen yg kebetulan melek elektro ato ke tukang service radio 4 band hehehehe.......
ok next....eh jangan lupa ngopi dulu...ama rokoknya dihisap dalam2 hehehehehe
cekidot skemanya......


ok jika udah selesai, agan tinggal hubungkan baterai dengan komputernya melalui inetrface yg undah kita bikin....????????
next agan2 membutuhkan software kan? pasti itu......
ok...... dari sekian banyak software untuk proyek ini saya cuma merekom 3 yg pernah saya coba

1. be2work
2. SBWorkshop 3.71
3. ACCPlus
kalau agan2 mau download......tanyakan aja sama mbah google dimana tempatnya....

selanjutnya jika agan2 sudah akrab dengan pekerjaan ini, para agan akan bisa membaca data dari dalam baterai lepi, kurang lebih seperti ini datanya :

DesignCapacity: 32767 mAh
FullChargeCapacity: 32767 mAh
CycleCount: 32767
Date: 2043.15.31 ymd
DesignVoltage: 32767 mV
ManufactureName: Read ERROR
DeviceName: Read ERROR
SerialNumber: 32767
ChargingCurrent: 32767 mA
ChargingVoltage: 32767 mV
DeviceChemistry: Read ERROR
Temperature: 30,5 C

Voltage: 32767 mV
Current: 32767 mA
RelativeSOC: 32767 percents
AbsoluteSOC: 32767 percents
RemainingCapacity: 32767 mAh

tapi dari semua diatas tidak menutup kemungkinan untuk merepair baterai secara hardware, contoh : ganti cell yang soak, ganti fuse yang putus dll.....
