MACBOOK WHITE 2009: BROKEN CHARGER SOLVED BY CHARGER CABLE SOLDERED PERMANENTLY

Hi all,
this is my wife old laptop..purchased back in 2009..still quite smooth and has been utilise by her and the kids. After several time facing the problem with it charger such as overheat, melting, magnet connector damaged, then fix it again as in  the link for several time.

then..i decided to install the charger cable permanently with the hope that it can last long. 

Since this laptop stay at the same place and not moving around. so, it is safe to, i guess, to permanently install its charger cable, as long as its working.

Figure 1: Disassemble the macbook to access the charger circuit (picture shown mainboard)

Disassembley and fixing step:

1) The first step was to remove back cover to have acces to internal circuitary.

2) Once back cover is open, disconnect the battery connector first to cut/remove supply from battery to the circuit. This is important to make sure no damage happen to mainboard during repair work.

3) remove battery by unscrew it.

4) then, remove the internal cooling fan ( unscrew 3 screw and lift off its supply connector)

5) after that, mainboard circuit can be taken out from macbook body after removing 6 screw.

6) locate charger circuit near the end of mainboard circuit (shown in figure 2).
Figure 2: Charger circuit.



7) add 5 additional cable from charger to charger circuit. Soldering work will be a bit tricky due to the tight space. Make sure there is no short circuit.


Figure 3: Soldering work a bit tricky.

Figure 4: Outcome after soldering. very tight in space, so precision are required

8) Once soldering are complete, check for any short circuit visually and by multimeter. After confirm that not problem with soldering, assemble back the laptop in reverse order.

9) Test the laptop with power supply once assemble is completed, and the outcome shown in figure 5 below.

Figure 5: Charger are tested ok after assembley of Macbook.

Testing with power supply shown that laptop battery charging properly. Now, my Macbook can work again.

Hopefully, this will help other who have similar problem.

HONDA RS150 TPS: RPM TAK STABIL BILA NOT ON THROTTLE DAN PENYELESAIANNYA

Assalamualaikum dan salam sejahtera Isu TPS ni berlaku pada tahun lepas, Ogos 2020 (milage dalam 24000km, baru dua tahun pakai) sewaktu saya on the way ke KL Masa tu tunggang motor full throttle yang menyebabkan RPM nya selalu mencecah ke CUT-OFF (utk makluman, honda RS150 saya ni tak guna ECU custom, masih guna yang standard). Jadi saya perasan, bila selalu tunggang pada RPM yang sampai CUTT-OFF, ini menyebabkan kesan tak baik pada TPS..jadi utk yang belum jadi problem TPS ni..boleh la cepat ganti ECU ke ECU yang tanpa cutoff. APA TU TPS? TPS bermaksud Throttle positioning sensor..bahasa mudahnya alat ni bertujuan untuk mengesan kedudukan throttle body valve dimana udara masuk ke enjin untuk pembakaran. Dengan itu, baru la ECU tahu berapa banyak bahan bakar yang perlu utk pembakaran berdasarkan bukaan valve tu.  Bila TPS dah problem, TPS akan memberi maklumat yang salah pada ECU berkenaan besar mana valve tu buka, jadi nisbah bahan api dan udara jadi tak betul la. maka, tu yang jadi s

HONDA RS150 IACV: IACV PROBLEM? RPM NAIK TINGGI BILA HIDUPKAN ENJIN?

 Hi semua, Salam sejahtera Masalah IACV saya berlaku selepas isu TPS wujud di milage 24000+km..kemungkinan kedua2nya ini saling berkait. Masalah IACV hadir ketika saya on the way balik semula ke Johor, ketika bahan bakar berkurang dari tangki moto. SIMPTOM  ? bila hidupkan enjin honda RS150 saya, RPM akan naik tinggi dan kadang2 sukar dikawal. tengah jalan pun, jika stop di trafik light, rpm akan naik tinggi dan mengaum bising..so, isu ni biasanya disebabkan IACV IACV APA TU IACV? IACV bermaksud Idle Air Control Valve. bahasa mudahnya nak control udara masuk ke ruang pembakaran sewaktu motosikal kita idle (tanpa pulas pendikit atau throttle) iaitu semasa tak bergerak. FUngsi dia mcm choke la pada motor lama yg guna karburator supaya moto mudah di hidupkan dan dalam masa sama injap dikawal dan dikecilkan bila enjin motosikal telah panas. IACV idling control valve (anak panah, lubang udara yang dikawal) APA FUNGSI IACV? Jika kita dah pulas throttle, IACV dah tak digunakan dan valve udara

HONDA RS150: MAINTENANCE SCHEDULES & MOST COMMON SERVICE WORK

Hi all, this is based on the guide book supplied with your motorcycle when you purchased your motorcycle. With this guide table, hopefully, easy for all, planning their motorcycle service. for me, its really useful since I'm doing my RS150 maintenance myself. The list below shows the most common maintenance schedule and what I did for my RS150 (already 22000+km after almost 9 months): Engine oil change, Petronas Sprinta F700: replace every 1600km Oil strainer: clean every 12000km Spark plug: replace every 12000km (can replace with a high-performance spark plug to reduce maintenance frequency) Fuel filter: replace every 18000km Coolant fluid: replace every 12000km following oil strainer clean work Below are is the maintenance schedule from the guide book. Hope this sharing help
