Hello, I'm trying to remove the password from an HP Elitebook 650 G10. It's motherboard has two chips, a 32mb spi (W25Q256JVEN) and 32mb ec (GD25B256EYIG). I have created a dump of each, but don't know which one(s) to patch. Could someone point me in the right direction or just patch it for me?...Yesterday, 06:29 PM

Hi guys, I have this macbook a1278 which doesn't have any image on the display, but when I turn it on I hear the chime.
I found the L9008 choke open and reset it.
When I turn on the macbook I have about 3v on pins 3 and 4 of the display so everything is ok but I still don't have the image.
On the backligt pin 21 and 22 I have 0v but the fuses are all ok.
What can I check?
I tried another display from a macbook a1278 but from the previous year and it still doesn't work.Yesterday, 02:17 AM -

I got this gpu that does not work, is not detected in windows(not shown as a pcie device),the heatsink got a little warm. MSI 7600 GT PCIE, NX7600GT-T2D256EZ.
Tested in different motherboards, same issue. I got it with a capacitor broken(one leg was left), and an broken indictor related to fan pwm I think.
As a hobby I tinkered with arduino, I got a soldering iron and a hot air gun, no experience in repairing(occasionally watched videos of northridgefix)
I measured randomly capacitors for short and found some shorts on a few, and found short on a few mosfets....05-23-2024, 07:30 AM -

Hi all.
Recently I picked up a vintage HP 37717B communications analyzer which uses one of these MML200 Coutant power supplies. Needless to say the PSU is not working, and surprisingly there is apparently nothing available on the web regarding repairing one of these. No stories, no schematics, zilch!
There[I] are [/I]however many companies offering repair 'services', however I don't have the luxury of sending it off, so am intending to do the repair myself.
I admit right now that I am no expert on smps repair, although I do have a grasp on the principle of the general...Yesterday, 08:23 PM -
Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

Going to replace op-amps in a guitar amp jcr072d
so TI versions have suffix D IP etc. There didn’t seem to be an explanation of these anywhere. I think they indicate the physical pin characteristics but what do they represent- anyone have a list.Yesterday, 03:06 PM
