upgrade 8gb on board ram in my dell 5290 2 in 1

[Mr.heinrich]

Greetings, i just decide to upgrade 8gb on board ram in my dell 5290 2 in 1, is it possible if i just swap the ram chip to 16gb or i should swap the other else like resistor or something. Please help me guys, thank you.

Just for information, my dell 5290 2 in 1 is using SAMSUNG K4E8E324EB-EGCF chip, this is 8gb chip ram.

SERVICE TAG: 160LHR2

Thank you so much.

I'm so sorry if my english isn't clearly.

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...

Hello guys
Because the unit is old (but only occasionally used) the loudness button causes some noise due to bad contact,
sprays did not work, so i decided to solder the pins that it connects on the pcb at the on (loudness on) position
i did that and it worked fine, i know from the bottom of my heart that the switch connects 2 pins and also d/c other 2 pins
on every position it have (6 pin switch), so i was curious what would happen if i clicked the switch off while the pins are soldered at on (so basiclly on and off at the same time), when i did so the sound is gone, nothing...

Hello,
I've got a SanDisk Ultra II 480 GB 2.5" SSD (SDSSDHII-480G)

Controller: Marvel 88SS9189-BLD2

Symptoms:
- the drive is completely dead, no response when connected to the computer,
- current consumption (0.01 A)
- under thermal imaging the only component that heats up is the controller,
- I checked the voltages according to the thread ([url]https://forum.hddguru.com/viewtopic.php?f=10&t=40329&view=previous[/url]) - all seem correct (typical 1, 1.8, 3 and 5 V).

Hello, I was updating the bios on my t470 20jn pf1q6dx5 using the soic8 clip that came with the Ch341A on the bios and pressed the clip too far back when i was taking it out and it knocked off what look like little capacitors, can this be repaired or bypassed with solder or a wire or what was originally on there, they are extremely small. I have attached two pictures, one with the capacitors on and one with them off. It took me weeks to figure out why the board wouldn't power on. I thought I had broke the bios. THe machine turns on for a second then turns off.

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....

I picked up this TV that the prior owner said - just died.

Tested the fuse - burnt. A dead capacitor is visible too on the hot side (CP801). Got the replacement power board (cheaply - used). Replaced the board - the TV turned ON!

Now, about a month later (yesterday) I noticed the left side of the screen was flickering from time to time. That was already happening with the antenna input, not through HDMI.

Also, some glitchiness with a Fire stick on HDMI3 - I hit an app with quick dark screen in stick, the TV goes - no input. Then I had to choose the stick...

Hello Badcaps!

I am trying to troubleshoot my Allen & Heath Xone:02 DJ mixer. I have had this for somewhere close to 20 years and have played music through it in one form or another pretty much every single day since I've had it, though these days it's usually from a wireless streaming receptacle (Apple Airport) more than the turntables that are also connected to it.

This week my music stopped working, and after a bit of a wild goose chase, I realised my mixer was dead. I checked the 500mA fuse in the device beside the power supply and found it was blown, so I replaced...

Hello Guys,

I am not familiar at all with plasma tv's but i tried my luck anyway since business is so bad. We gotta try, right?
Anyway, the original problem was a tv clicking and not starting due to a short circuit on the Z-Sustain board (on the right side from the rear).
I found two transistors shorted (30F123) and changed the gate driver ic's as well. I think they were FAN73711. I soldered for dry joint on power supply, Y-Sustain and Z-sustain. Started up the TV and the short was gone so i had an image but.....

Hello,

I am new to repairing computer electronics, so excuse any mistakes I make.

A friend of mine had a broken graphics card (MSI Radeon RX 5700 XT MECH OC) and gave it to me. It does not power on or show any signs of life.
I identified what looks like the remains of a blown capacitor at the bottom of the board (see picture).

I wanted to replace the capacitor, but I have two questions:[LIST][*]Does this repair have a chance of working? or is a blown capacitor a sign something else is wrong?[*]How do I determine the rating/value of this capacitor?...

I have a PS5 in my shop that beeps when the power button is pressed but the light does not turn on and the fan doesn’t move at all. I tried replacing the power supply because it had some roach bodies in it but the rest of the device had no signs of infestation, and it does the exact same thing. Then I tried replacing the HDMI chip (MN864739) because I saw somewhere that it could be the culprit but still no change. Does anyone have any other suggestions or things I should test on the board or is it likely dead? Thanks!

Can someone tell me what the Capacitance value, voltage, etc is for these 68 C79 caps are? Where could i pick up a replacement? Thanks in advance!!...

Hi I have a touch screen monitor. It work fine for many years, but now It shows its age!
When I turn on the monitor, white lines appear on the display. They jump for a few seconds and then the display goes off.
Can you give me some pointers on where to start with the diagnostics.
There was a trail of dried light brown liquid on the board that the display connects to, as if a capacitor had leaked, but I couldn't find one. I cleaned the circuit board and resoldered the legs where this liquid was, but to no avail....

Hi there,
I have a Mac on the bench that wouldn't turn on, it didn't have PPBUS_G3H voltage.
I replaced the IC U7000, ISL6259 and the green light came on, the cooler turned on and showed the video, but I noticed that PPBUS_G3H is at 9.45V and the U7000 is heating up a lot.
I took resistance measurements for the earth and did not find a short circuit.
I measured the resistors connected to the U7000 and found no different value.
I searched the Forum and didn't find anything like this.
Can anyone give me any advice about this problem?
Thanks in advance.

Dear friends of the community, I hope you can help me in this case, this notebook came to me with the fault that does not turn on, when the source is connected it indicates that it is charging, when you press Power 2 or 3 seconds pass, when it only steps once on the Power LED, that's all the fans do not turn on it does nothing more than charge the battery.

I have had this TV many years without fault, however aprox 6 months ago I fitted a new set of backlights as some of the lens caps had fallen off.

Was working fine, until 3 days ago, when watching TV the screen just went blank (still illuminated)
I turned the TV off and left it around 12 hours, and when turned it on again it seemed to work perfectly again. After around 45 mins the screen went blank again.
Left it off overnight and turned it on, and the Smart TV logo came on as normal, then screen went blank.
