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.

Hi all, for the past 14 months, I have been travel long distance around 160+km go to office and back.  Every month, average distance around 3000km and I am using my CT100 for that travel,most of the time. It is quite safe travel, although with many heavy vehicle using the same road with me. However, it become concern to me lately about my safety as I mostly left my office quite late. sometimes, its night already. so, I need to make sure that vehicle on the back can notice/see me and know what is my next move during my travel. Therefore, I decide to install extra rear light which is third brake light, turn signal and also tail light at the most visible position (decided to install on the rear storage GIVI box). Figure 1: brake light and turn signal light test Purchased the LED light as below which had all the function. Tail light, brake light and turn signal. Figure 2: LED 48 brake, tail and turn signal. Then, wiring installation are required. Refer to t

Hi all, My HP Laptop charger  suddenly not working 2-3 months ago and already managed to buy new charger. But, but, now have time to have look into old charger to troubleshoot the problem and solve it if possible. Symptom of problem with charger: no DC voltage at output dc connector. Checked the main plug fuse, and its ok. So, main problem should inside the black square converter box. In order to fix it (troubleshoot the problem or find the problem), the cover must be open and this is by breaking the black cover. Figure 1: Opening the case for charger figure above show picture after case or cover is open. then we can visually inspect the component inside the charger. Figure 2: Two of broken capacitor Figure above shows internal component of charger. input supply are from left side which will pass through some important component like rectifier, capacitors, inductors and transformer (part of converter and filter). AC supply power are converted to DC supply that

Hi, my wife complaint lately about our water kettle not working. this is second kettle having the same problem... I realised that two of my water kettle with new base design having the similar problem, which are its live metal connector, that supply power to the kettle, changing its colour and corroded due to high current flow.  Due to high current flow, live cable seem to be overheat causing some plastic around it melt. Figure 1: first kettle (morphy richard 43904) having issue with its base connector Figure 2: Second kettle from Faber FCK135, also have the issue with its base connector. Figure 3: unscrew the bottow base to access the internal part of base. and most of the time, causing the plastic around the cable melting and ending up open circuit to the kettle which lead to unworking kettle. Figure 4: It was found that life connector and plastic holder around it have been damaged due to overheat. What I did is disassemble the kettle base..and find th

Changing battery for C180K is quite an easy work.. In my case, my 14 years old battery are suddenly dead. Although, I managed to strecth its life beyond its normal life cycle, but, it is time to replace that battery. Its not able to provide enough current anymore to crank the engine. Though, still work for smaller engine. There is no specific procedure in doing this procedure..however, you might loss the setting in the car unless we have additional backup battery when doing replacement procedure. In my case, i dont have backup battery, so, i have to accept losing my setting.

Hi all, anyone having trouble with their door lock acting like a machine gun? this is common problem with mercedes c180k w203 car. usually, door lock button keep bouncing whenver we try to lock the car using remote. and most of the time, very difficult to lock the door. Figure 1: W203 C180K that has common problem of bouncing door lock main culprit is broken spring inside the actuator located in each door. in my case, both of my front door actuator spring broken. so, two choice for me to fix this problem. either send the car to repairman or do the repair myself.. i have asked the repairman about the cost and labour to fix the problem, and he said, cost about rm450++ for just one actuator part. and labour about 200-400 to replace broken actuator. so, total for my car will be about 1200++..thats quite hefty cost. in the end..i decide to do it myself, and i am going to take some time to study, and have it done in my own free time. cost will be less than RM100 for

Hi all, last month, one of my sister in-law complaint to me that she not able to control her fan speed. and fan become very slow in term of rotating speed.. So, the fan is no use as they not feel any blowing air from the fan. First is to get the model detail: brand: panasonic model: f-my-143 5 blade fan Figure 1: Outside cover of F-MY-143 panasonic fan remove the cover to get access to the internal board. this fan different than common fan which have separate regulator circuit on the wall. This fan come with remote control, so, all the speed control circuit and motor circuit is on the same board. Figure below shows the common circuit inside the panasonic remote control fan Figure 2:electrical board in panasonic fan F-MY-143 Common part that always associated with the fan slowing down is the capacitors. figure show with arrow the suspected damage parts. one, is 0.82uF 275V capacitor , another one is 0.1 uF 275V capacitor that usuaslly smaller in dimension com
