See the attached drawing of the chip I am trying to identify. I think the last character (the 'H') may actually be the manufacturer logo, but I am not sure.
This chip is part of a hand held device that detects metal. Its called a pinpointer, and is used in the metal detecting community. The chip is located on the main power rail which is from a 9 volt battery, noted in the drawing.
I tried many searches to find the part, but did not see anything that looked close. But then I have very little experience doing this and I could have easily missed something obviou...Today, 07:27 AM -
I have a card that does post at all, the owner said it does go into windows but it gets stuck on the logo with artifacts, I have no idea if he is lying or not... I tried the card on my pc and it does not post at, no beeps, no bios nothing just all fans turning and nothing else. I tried plugging DVI or hdmi but nothing, I tried unplugging the 8 pin plug from the power supply and it's the same thing.
I just want it to post and get into the bios at least.
Forgive me if I am wrong, but I tested the 3 PCIe 12v power pins on the left(550ohm) and the 4th one from the right 3.3v (400ohm),...04-18-2024, 02:42 AM -
my laptop has a weird power-on issue.
Once the laptop has been powered on, it can restart/ wake just fine on battery power or Adapter, ONLY If i have not closed the LCD.
If i am running on battery and have closed the LCD (even momentarily). it will not power-on/ wake-up on battery power no matter the battery percentage.
but once i open the LCD and connect it to the adapter (even momentarily) it will wake up gain and I wont experience any issues till i close the LCD.
i do not know where to look for repair.
thank you all for any advice.04-30-2024, 04:36 PM -

The laptop won't start. When plug power supply, on 19V in gives me 0,14A, without turning on the laptop.
I check it with thermal camera, and there is one resistor that is very hot, I change the resistor with new on but the result is the same.
In the attachment there is schematic of the resistor area, and schematic of the laptop.
I can't understand, why this resistor is getting so hot....Today, 01:24 AM -
Hi All
Been a while since I have been here, and a bit rusty.
I have the above laptop motherboard that was working and now the charging circuit is faulty.
Have 19v in fine until it hits PU4403 - not shorts I can see and thermal cam reveals nothing.
I have swapped out the ISL9538 and also the two mosfets (PU4403 and PU4405). Have 2.8v at the power switch, which pulls low when pressed - charging light comes on and goes straight off
Below are measurements (pin names are per the datasheet for the ISL95338 (couldn't find one for ISL9538,...05-03-2024, 03:25 AM -
