I just noticed Avira says there are no trackers on me. Where are they? I demand my trackers. I want to see at least three by the time I come back here. You'd better get with it TC.Lol.

Hello
does someone have the schematics for dell E5470 0P88J9 A00 please? -
Hi,
Finally got time to fix this board up.
At first it didn't give any POST codes. Turns out it was an unsupported Celeron D cpu. After dropping in an Celery 2.6gHz the CPU came out of reset with clock signal, but still no post codes. For a while it did work when I applied pressure to the ADP3168 chip, but on next reboot the MOSFETs started to burn. Then I left it as is for months.
Now I came back prepared. Replaced the bad MOSFETs and the ADPxx18k drivers. Now I don't get any MOSFETs blowing up issues anymore. But sadly, the Vcore is missing. The whole VRM isn't... -
Hi there. I am trying to repair an Acer Nitro 5 AN515-45 and it's giving me some trouble. I have access to SMD rework station, variable power supply, digital oscilloscope, thermal camera, multimeter, stereo microscope.
This laptop will boot and run from the power brick and/or the internal battery, but it will not charge the battery. NirSoft BattInfo tells me the charge/discharge currents, so I'm confident in saying that it's not charging. In addition, there's no increase in voltage at the battery connector when the laptop thinks it's charging, not even a few millivolts.
I've downloaded... -

Design of CCFL Backlight Inverters with Frame & Bar Cores
Summary
Portable devices, such as notebook computers and personal digital assistants are developed rapidly nowadays, which places an increasing demand on display technology. The LCD with cold cathode fluorescent back lighting satisfies the requirements on display performance, size and efficiency.
The backlight inverter plays a crucial role in supplying the power to the lamps of these flat-panel displays.
The frame and bar ferrite cores, described in this brochure, are especially designed...10-07-2024, 04:26 AM
