Hi, everyone. First post of an actual repair. I'm a technician but a complete newbie with laptops.
So I got this Dell Inspiron to play with.
No charger, so I connected to my bench PSU.
The laptop also didn't include: hard disk (I added one of my own for testing, see below) and wireless PCB (but I doubt this could have anything to do with this particular failure).
------What it did (and didn't do)------
1) I turned it on and it powered on. Powered down in 2 seconds by itself.
2) Removed RAM, changed slot. Same...04-04-2024, 12:39 PM -

Hello, I have this HP Spectre 14-ea0023dx (wrong model number in the title) laptop with an issue. When you close the lid, the screen goes off. Then, when you open the lid the screen remains dark while the computer is still running.
I suspect the issue is with the lid sensor which I am assuming is a small magnet located in the lower part behind the screen bezel.
Could someone, please confirm this? Thanks.Yesterday, 04:32 PM -
Hi,
I'm looking for ideas on how to aproach this, I spent many ours already.
The dryer doesn't get hot, only warm and then gives error E25 (Fault with the sensor or electronics detected).
Now I'm testing it using the service mode - it gets the temperature of the heat pump liquid to 52C and then it stops the heat pump. After few minutes it then produces E25.
I tried to understand if it stops the testing because the final temperature was reached and I don't think that's true. While it was running, I heated that sensor using hot air to 80C and then it stopped. So I think the...04-12-2024, 06:24 AM -
Hi as you can see from title, I have a samsung tv here that will show the smart tv logo and then no picture after that even hitting input or menu on remote and shows nothing but the backlight still appears to be on. The tv will turn itself off after a minute or so automatically. I'm somewhat confused if this is either a eeprom problem or a bad led strip problem. The power supply makes a pretty noticeable humming sound when it's turned on leading me to believe one of the leds are shorted but idk honestly. Any of you guys have any help for me? I have a good multi meter and can take pictures of whatever...04-13-2024, 10:05 PM

Hi,
Sooo - our IT got a pile of old iPads that the sales guys have been mistreating. These are free for grabs if you want to try to get one working. Thought I'd give it a try - if I get at least some life to I can give to my kid to entertain during a car rides.
But the iPad it self - its a 5th gen cellular model. When I initially plug it in it was completely dead. It was not recognized by my Mac nor it started to charge. Disassembled it opened up the battery connector and checked the battery voltage. My multimeter showed 0,7v. Had a spare micro-usb charging board lying...Today, 12:51 PM -
Hi Guys, I hope someone can assist me me. I have a HP Probook G2. It came in for not charging. When charger plugged in power light on the charge port was flickering as well as the caps lock light. Not a pattern, but inconsistent. I found a faulty mosfet on the power input which I replaced. Problem I have is that it does not start up without a battery unless I use a 18.5v charger. It does however start with the 19.5v with the battery installed, but the battery charge voltage is 2.58v. The required charger for this unit is a 19.5v of which I have tried several. The battery is bad and have ordered...Yesterday, 07:37 AM

Hello
working on a2141 macbook, board number 820-01700 which has no wifi\bt and also no connection with LAN cable.
initial visual inspection the board looks good no visible corrosion or damage.
i found that PP3V3_G3S_X is shorted to ground (around 1.5ohm short)
and also PP3V3_GS3_WLAN i shorted to ground (same ohm reading, around 1.5ohm).
the board is working but no WIFI\BT as i mentioned.
with the usb c cable connected for measurement i noticed U8215 i getting EXTREMELY HOT
so i pulled it out figuring it might be causing the...Today, 01:18 PM -
Hello, working on a laptop (MSI GS75 9SG-242US, Core i7-9750H, 2080 Max Q) and after replacing the screen and forgetting to disconnect the battery prior, I have no visible indications of power anywhere. It was working perfectly fine prior to the screen removal and replacement. Checked the motherboard PCB visually near the LCD connectors and didn't really see any indications of damaged surface mounted components but haven't looked under a microscope yet.
Battery charging light isn't turning on when plugged in and pressing the button does nothing regardless of being on battery power...Yesterday, 09:35 AM -

Good morning.
I have a problem with my LG Smart 43UF640V TV. It starts, the backlight comes on but nothing is displayed on the screen and there is no sound.
I thought it was a TCon problem and ran various tests. If I disconnect one or the other of the cables from the tcon to the panel then the screen is white on the side where the cable is disconnected and black on the other side. If the two cables are disconnected the screen is completely black.
In the 4 configurations I measure exactly the same voltages on the tcon card (model V15 43UHD TM120 Ver0.4) :

Hi,
a few weeks ago I saw offers for a MEC1503 on aliexpress. Out of curiosity, I bought one and was a bit surprised when the chip arrived: as you can see in the picture, it was significantly smaller than the original in my ThinkPad. Does this chip really exist in 2 sizes or is it just a fake?
