ACER ASPIRE IDEA 500 POWER SUPPLY PROBLEM (FSP120-40GLS)

Hi, its has been 3 years that my acer aspire idea 500 power supply broken (not working). since the replacement power supply is difficult to find in here (Malaysia), I have to modified the supply cable on the connector to match my aspire idea power supply (PS).


old bulky PS

 the original replacement is about £50 now at UK..While, here in my home country, no chance to find it. so, I have to find alternative way to make my idea 500 working. 

one way was to use old power supply (twice the size of its original PS) and rearrange it cables to PS connector to suit the idea 500 supply. That was done (and working) 3 years ago.
these pins used for removing the cable from old PS connector for rearrangement


Recently, I managed to get some courage to open my dusty aspire idea 500 original PS casing to find out the source of the problem.

120W original aspire idea 500 PS model FSP120-40GLS
 In there, I found several bulking and leaking capacitor which could be the main supply problem.
with little bit of soldering skills, I replaced the capacitor (20 pence each = RM1 each)

after that, my aspire idea 500 PS are working again inside acer aspire idea 500. with a lot of saving from buying the new PS.

    Thanks for the information. Then I will try to fix mine as well. Is it possible for you to provide a list of the replaced capacitors (the types)? Then I can order them in advance and replace them one by one.

    Hi Django, thanks for reading my little blog...about the capacitor, just order normal electrolytic capacitor..1000uF 16V 105degC temp. any brand would do. you will need about 8 pieces...please also check the fuse the go through life (brown cable)..it might blow as well. Hope this help

    Hi, may you tell me how much are electrical potentials for OT and PW_OK signals? My aspire 500 doesn't work and I measured a value of 0.15V for both previous signals. The other potentials are ok.

    I modified the pinout of a standard PSU and the media center works fine, with 5V for OT and -12V for PW_OK. Anyway it looks like 0.15V is the right value for this custom PSU.
    PS: I measured values without load.

    Sorry, I mean -12V for OT and 5V for PW_OK.

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
