No luck flashing with that bin (or my unmodified one):
[CODE]Error 167: Protected Range Registers are currently set by BIOS, preventing flash access.

Protected Range Registers.

But, I have managed to reset the password!
I reached out to Lenovo support and they gave instructions. They weren't sure if they would work but they did.
Other instructions I found said that moving JP35 to 2&4 and powering up was enough, but this...

Thanks [USER="237374"]SMDFlea[/USER]
File size is similar to what AFUWINx64.EXE gives at around 12MB.
I've attached both dumps from FPTW64.

Thanks. Is that the only way?
I've been hammering google to try to work it out and came across FPTW64.exe, part of IntelCSTools - specifically [URL="https://github.com/CE1CECL/IntelCSTools/tree/ce1cecl/CSME%20System%20Tools%20v12%20r38/CSME%20System%20Tools%20v12%20r38"]CSME System Tools v12 r38 on github[/URL] (Flash Programming Tool/WIN64/)
After some blue screens, I got this to dump the bios in safe mode. The bios image is 16MB and in UEFITOOL it appers as "Intel image" like [USER="539585"]DARNO786[/USER]'s.

I tried dumping using AFUWINx64.EXE which is included with the latest bios update I downloaded from Lenovo. It produced a 12.5 MB file. [USER="539585"]DARNO786[/USER] 's file was 16MB 🤷
Next I tried using my dump with autopatch and it says:
[CODE]dump.bin is corrupted or does not contain a valid dump.
There was an error... Aborting.[/CODE]DARNO786...Leave a comment:

I have the same problem with my M720q. I'm struggling to find detailed instructions.
Should this patched dump work with my machine or do I need to get a new dump?
If it should work, how do I flash it?
I downloaded the latest bios update from Lenovo and it contains a .ROM file, so not sure what to do with a .BIN file.
If I need a new dump, how do I do that?

Re: M-audio AV30 speakers recap and repair
Thanks, I've added my country to my profile: Scotland. Usually get stuff from Farnell or RS.
The ceramics have 104 on them, so I think that's 0.10 uF.
I'm not sure if I'll be able to read anything off the burnt out diode. I'll try and de-solder it and see. Hoping SnowKitteh might have the details.Leave a comment:

Re: M-audio AV30 speakers recap and repair
Also trying to repair a set of these. On mine the zener diode Z1 has burnt out, and the electrolytics C48 and C47 (220uf 25v) look suspect. There's another zener (Z2) and a couple of ceramic caps (C4 & C10) nearby which I'd also like to replace.
Does anyone know of suitable replacements for the zener diodes and the ceramics?

Re: Dell Inspiron 6000 works via battery but not charger
Thanks siddiq. All the caps you mention measure 4.7K on both boards, but on the bad board it takes a few seconds to reach that value.
I checked around PU8 and found suspect resistances on a few components (bad vs good):
PC109 - 9 vs 18.58K
PC111 - 42 vs 18.5K
PR141 - 5.7K vs 9K
PR192 - 5.8K vs 12.12K
What sort of component is more likely to be affected by reverse polarity? I'm guessing resistors and capacitors (like these) will probably be okay? Most of them are really tiny...Leave a comment:

Re: Dell Inspiron 6000 works via battery but not charger
carlo0014, thanks but checking the power supply was the first thing I did, after my initial polarity mistake.
ben7, thanks. DOCK_DC_IN only appears on this part of the diagram. I assume it's for a docking connector, but there no sign of one on the board, not even pads.
I'm very reluctant to try to remove PR11 - it's tiny. It measures 150K in circuit which is correct. PR13 also appears okay, measuring 100K in circuit.
With PC2 and PQ3 removed (but PR11 still present) DOCK_DC_IN to ground...Leave a comment:

Re: Dell Inspiron 6000 works via battery but not charger
Almost 12 months to the day, and I'm back looking at this laptop. I now have a couple of other Inspiron 6000 boards to compare with (can't just substitute because the LCD isn't compatible).
I decided to measure some voltages around the power jack. Here's the an image from the schematic.
On the working board, the power supply supplies 19v to pins 2 & 3 of the connector. DCIN+ measures 19v. After PL2 I also get 19v - top of PC2, PR11 and pins 1, 2, and 3 of PQ3. PQ3 puts out...Leave a comment:

Re: Dell Inspiron 6000 works via battery but not charger
I thought pin 1 (OUT1) went to ground at the bottom of PQ9 before the intersection after PL12?
I removed each component in turn and checked the component for a short and then the two pads from where it came. Each time the component was ok but the pads still shorting....Leave a comment:

Re: Dell Inspiron 6000 works via battery but not charger
I removed all 3 and they were ok, but the short remained. Only then did I notice the link on page 43 - if you look left of the three components and PR59 there's a link going down to ground and on to pin 1 of the max1845 (if I'm reading it correctly). PC52, PC51 and PD18 also connect to ground.
Ok, thanks....Leave a comment:

Re: Dell Inspiron 6000 works via battery but not charger
Thanks!
Thought I'd found something. A diode, and 2 caps in parallel showing a short (PC52, PC51, PD18). For reasons I don't understand the schematic shows there is a link shorting these in the circuit.
Found a mosfet apparently shorted (PQ29), circuit shows a diode (PD29) in parallel and on the PCB... no diode both pads deliberately shorted.
On closer inspection pin 4 isn't shorted to the others.
So, can't find any shorts in the "P" sections - caps seem okay and all...Leave a comment:

Dell Inspiron 6000 works via battery but not charger
Hello, hoping someone can give me a few pointers to help troubleshoot this.
I was having issues with the original DC adapter and tried a universal one instead - unfortunately I got the polarity wrong.
As a result the laptop works fine from a charged battery, but when using a genuine adapter (borrowed from friend with identical laptop) the adapter is not detected at all - no lights, no unknown adapter, no power, nothing.
So I removed the motherboard and had a poke around with a multi-meter. The socket seemed ok, but I resoldered it anyway. I found one capacitor... -
Distorted audio from set top box
Box in question is a Grundig GUDSTB2000 Freeview (DVB-T) Receiver. Nothing special just wondering if it can be fixed.
Picture is fine, channel change possibly slow, but the audio is distorted and slightly out of sync. Box has two scart outputs and a digital audio output. Audio is the same from both scarts. Haven't tried the digital audio output (not sure if I can).
It's powered by an external 12v source which I know to be good. Inside there are around 40 electrolytics made by Secon and Chang. CPU is Zorran SupraTV ZR39162PQGC.

I think I'm just going to give up on this one Getting access to the boards while the TV is powered on is pretty difficult.

Re: Sagem Axium HD-L32 LCD - Horizontal Lines
Thanks for the suggestions.
The T-Con board is the one at the top centre behind the LCD, right?
It's marked V32B C3. Looks like this one:
How can I work out what the voltages should be?
[I should add (in case it's not obvious), this is the first LCD TV I've pulled apart I've repaired a few digibox power supplies, but just obvious faults.]...

Re: Sagem Axium HD-L32 LCD - Horizontal Lines
[Bumping my old thread as I've finally got round to opening it up for a look... ]
I was hoping to find some obviously bulging low quality caps, but the ones in the power supply section are all Rubycon and look fine. Mostly Rubycon elsewhere too. It's all quite clean inside too. I removed and re-seated the connectors between the mainboard and the inverter board and the other board connected to the LCD, but it's made no difference.
Here's how it looks on screen:

Re: CapXon & Teapo 400v 100uf Caps
Thanks a lot Gianni.
Can you tell me why you have chosen those ones? (not the brand but the specific capacitors).
Obviously the capacitance and voltage are the same and the temperature is similar, but should I worry about ESR or ripple or anything else?Leave a comment:

CapXon & Teapo 400v 100uf Caps
I've already posted about these in the Power Supply forum but not had any response ([url=https://www.badcaps.net/forum/showthread.php?t=8261]original thread[/url]).
I'm trying to identify suitable replacements for a large 400v 100uf cap used in a Thomson DSI8215 Sky+ HD receiver.
I've got a few power supply boards and the cap is either a Teapo or CapXon:
- TEAPO 100uF 400v SH105°C 09/05 A3
- CapXon 100uF 400v KM105°C C616 VENT
