Fortinet 50E Slowing down internet throughput

[mon2]

Hello. Coming to you from the laptop forum. Have a client with the Fortinet 50E that has 320 Mbps as internet input speed but only 20 Mbps output on each and every downstream port (using FAST.COM to benchmark).

Reseller is stating the Fortinet is 'worn out' which does not sound logical at all unless the flash memory is 'worn out'. They, of course, want to sell another + onsite installation fees.

Can anyone share feedback on this unit? What can cause this sluggish behavior. From our knowledge, this device is snooping on the traffic to halt viruses / hack attacks, etc....

Hi guys.
I ordered used LG 34UM88 monitor which should come with 19V 5.76 A adapter from LG.
I payed for monitor but sadly I got scammed it came with 14V 58W Samsung adapter.
Luckly I did not even tried to turn on monitor, but I think they used the 14V adapter.
Is it possible to use 14V adapter and what already damage could happen?

Hello good people of badcaps.

im back with another question

Im trying adjust the current bias accordingly to the manual, but my meter is showing the same value no matter whatever position VR-804a/VR-804b is in.

DC bias is adjusted and is working as intended.

Is my settings on the multimeter wrong ? or should i look for a bad component

note: all transistor are new

Looking for a BIOS for HP 255 G8 (HPL51 LA-L021P).

The main problem is that the laptop will crash while booting to OS. Will crash even on booting from USB, like a Ubuntu or to a Windows 11 installer.
Before junking the board I would try the new BIOS if it does anything.

Thank you!...

Hello,

im actually trying to save a d1500 delay from yamaha. I found the service manual but schematic is missing and BOM list is a bit unclear as components listed have no reference linked to the pcbs... In my case, one zener diode was broken (114 code on the pcb in attached file) and couldn't be repaired : it was a zener type package. In the BOM list i found 3 reference on this board : 1S555 (can be replaced by 1N4148), RD4.7EB2 (approx 5v rectifier), RD7.5EB3 (approx 7v rectifier)...

Actually the cathode goes to VCC of sram M5M5118P, without this diode missing, i have...

Hello!

I am still learning on laptop repairs and I am currently working on the above mentioned device.
Currently the laptop is dead (no power on). The device takes 2-3 mA when 20v are injected onto the charging plug.
Main power rail is present (20v), but no other power rail is present, including the 3v and 5v. I noticed that when no power is connected the 3v and 5v coils have large (normal) resistence to ground, but when I plug the power, both are being shorted to ground.
I wonder is that an expected behavior or there is an outer protection activated.

Hello.

I have an Asus X705UV which no longer starts since the last Windows update. I suspect Windows Update of having tried to update the bios and having corrupted it, because currently, I have the charging indicator when I plug in the charger and I have the power indicator when I press the on/off button but nothing more, not even a fan running.
Could someone check this bios and if it is broken, repair it?

Sorry in advance, google translate is useful but not perfect. 😂

Hello,
I recently got a PS5 with an EMD-032 board and someone before me “tried” to change the HDMI port. Unfortunately, a few SMD components are now missing, see image. the top one should be a 100nF cap. but what is the lower (0Ohm resistance?)

Hi,
I have this dead laptop, if I plug the charger I see only charging led light blinking 3 times.
I disassembled it, removed the battery and checked with my multimeter:

red arrow input connector 19v

green arrow first mosfet drain 19v

white arrow first mosfet source 3v

yellow arrow second mosfet 19v

pink arrow 3v

blue arrow third mosfet shorted to ground

current resistor 3 volts on both sides

Any advice? I have a thermal camera and I could inject low voltage if needed.

I've gotten into the habit of Looking at peoples Mechanical Hard drives with a Ubuntu thumb drive to boot their system.
I understand the raw values are not really uniform between manufacturers, but I have noticed that high seek and read error raw values at the very least correlate to a drive that is going to have sub par access time, and extremely slow OS booting.
The odd thing is I've often seen very high seek and read error rates on drives with fairly low on time.

Does anybody have any other takes on evaluating smart data? I've used Crystal Disk Info, It seems to present...

Couple of Windows 11 machines have come in this week with the same issue. After you login, the taskbar will not appear (or just be a black bar). No access to Start Menu. Task Manager (use CTL+SHIFT+ESC) works, however the Performance stats seem stuck with CPU on 100% for Task Manager itself. Trying to exit Task Manager result in it hanging as well. No issue if you boot into Safe Mode.

Hi,
I got corrupted bios bin file, which way is correct to repair.
File puts errors on Me Analyzer and cannot open in FIT.

To open in FIT I made:
1. Extract MFS and EFS using MEAnalyzer from other bios file with the same parameters
2. put it in HxD to my file
3. MEAnalyzer shows 1 error after that
4. file opens in FIT

and:

1. extract current dell bios on website
2. put System BIOS with BiosGuard v1.30.0.bin using FIT
3. MEAnalyzer OK no errors

I have the above mentioned MBP, quick scan with thermal camera revealed that only U3200 was heating up. I found that C3208, C3219 and C3205 were all reading ~6.8ohms to ground.
so I swapped U3200.

I connected the PSU again for a quick check on thermal it's drawing about the same amount of current but now I'm seeing only heat radiating from U7800 and the T2 chip from under the black shielding fabric, and the bottom of the board.
It's hard to judge the actual temperature without removing the shielding.

I had this Lenovo Flex 3 1580 worked fine. Suddenly it won't power up. After open it up, I found it can start with lid closed when I plug in the power adapter.

But the mouse pad and physical keyboard won't work. The power button won't do anything.

Hello everyone.
I'm troubleshooting a cisco switch, which seems to have an issue with the PSU.
The psu has the following power rails - +12v, -53.5V and +3.3V
When connected to power, the +12 and -53.5 seem to work fine, but the +3.3 starts at ~3v and then goes down to ~0 (I guess this is the cap discharging). This happens both when the cable is connected and not to the switch board.
Any ideas what might be causing this behavior?

For those in 220V locales, anyone power their SMPS with DC, and how high of a voltage is okay?
What kind of PSU?
I suspect that 240V * sqrt(2) = 340V DC is probably fine because that would be about how much the the primary rectifier ends up with peak voltage. Just wondering, other than input capacitor voltages, can one go up above this 340V without damage? Will that input capacitor be the upper bound?
Wondering if exactly that, can I feed near 400VDC into bona fide specced at 220V SMPS without damage?

I did a hard reset on it (twice) clearing all data & settings out.....will still do this. Even removed the batteries from the remote....in the unlikely even there was a stuck key... Still doing it. I did not set up any of the 'smart' functions, I just fed it a source from a HTPC. It doesn't matter what input is selected.....still does it. No rhyme or reason...

Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge.
