I am trying to get a set of Creative T40 computer speakers to work again of which I believe the problem is bad caps (470uF @ 35V). So I get a generic set off Aliexpress. The brands are meaningless, but if anyone cares it's a "Chongx"
When they arrive, to my surprise it's much smaller than the originals. These are 8mm x 15mm whereas the OE is 10mm x 20mm. Unfortunately my meter does not test capacitance but I'm guessing there's no way this meets spec at 80% the size.
Thoughts? Is it still worthwhile or safe to try and install these to see if...

11254-3 charging problem

by madjid911hello I have an acer nitro 5 model N20C2 (motherboard FH51M LA-J871P rev 1B) which does not charge, it turns on perfectly but when I plug in the battery, we see the charging indicator and the charged battery logo but it turns off a few seconds later, and there is no way to turn it back on, you must then disconnect the battery and the charger. If I turn it on without the battery it works fine.
I changed BQ24781 but the result is the same, I put after BQ24800 the same, I then checked all the resistors and mosfets, everything is ok, I bought a new new battery but the result is the same...04-20-2024, 07:58 AM -

so i repaced, pqb3, pqb4, and makes no change, still no acdrv, i replaced bq24781 and makes no change, still no acdrv, if someone can help pls, thanks, this are the schematic and boardview

by TheOtherGuySo I'm having difficulty finding line drawings for this motherboard NM-C53. My charging port was broken. So I replaced it with a terrible solder job. Problem is pin 3 on the drawing I saw on here has it listed as adapter-id. Now I checked my other pins and I have continuity (resistance check from power to ground). Pin 3 shows nothing. Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge. I have read that pin 3 is usually tied to a resistor that identifies the charging power thus disabled the ability to charge if it fails the check. I look at my board...Yesterday, 07:27 AM

by DanPokaI bought 2 of these supplies off of Temu , it said they were original for Samsung phones and I bought them cheap so I thought I got a bargain. Looked inside and they are definitely not original. Could you provide any pointers about safety, other characteristics etc. I cannot identify components 5433q 349DJB (what is that?) and it seems it has normal resistor instead of fusible resistor. Is it a fire risk. Lots of questions. Thanks for any time spent on this..9 PhotosToday, 12:56 AM

Hi.
My Hp G6 laptop died while using it.
I opened it up and used a thermal camera on it to see if anything was getting hot. The RT9513 chip (EQ ED B1Y) which is supposedly a battery charger ic was getting hot. I ordered a new one and replaced it but its still red hot. Where should I look next?04-20-2024, 10:02 AM -
