Re: Which is better? 32-bit or 64-bit on the edge of max 32-bit memory (Win7)
64-bit..!
Whether you install 64-bit or 32-bit OS is not decisive factor in your machine. The decisive factor is whether you have HDD or SSD. With HDD machine will seem slow and sluggish, especially after you install office. An SSD will make that machine fly.
Another thing that can make it fly is Linux, perhaps Manjaro with XFCE. So long as Microsoft Word and Excel are not needed, it's good.
I have Q8300 machine with 2gb RAM and SSD, office installed, it is fast....Leave a comment:

Re: Chuwi HeroBox blown components
Well here is my plan, doesn't mean it is correct, but this is what I would do.
This chip
GST5009
LF
2146G
We need to find schematics from some other device where this chip is used. Caps and resistors and other things that goes with this chip will be the same. Then we figure out what is blown and this way we would know the values.
For example: I'm not saying this example might give positive results. But ASUS n61vg uses this chip. Here is the boardview for it. If this...Last edited by u666sa; 05-29-2023, 05:30 AM.Leave a comment:

Re: Core 2 "gaming" build with SLI
Hmmm. Mine has Q8300 and 2 gigs ram now (for now at least), runs Windows 10 Pro for Workstations 64-bit just fine. I mean, web browser, latest chrome, foxit pdf, boardview software, no problems. I wouldn't call it useless, it's still a work station, ideal for live under the work bench for manuals and web. All I want for mine is xeon CPU and big cooler and more ram, and maybe better card, perhaps I can find a broken card and fix it.
I mean, what else can you ask for? System like this will be good for another 10 years or so,...Leave a comment:

Re: Core 2 "gaming" build with SLI
There is a nice E5450 and X5460 on Ali. Both of those chips are capable of running at 4 and even 4.5 GHz with proper cooling. Frequency that you kinda need for one of your cards, not to mention two at the same time. Here is more info - [url]https://xeon-e5450.ru/socket-775/e5450/[/url]
Now.. Anyway you spin it, your CPU is old....... So gaming wise, games 2015 and newer will have problems, some won't even run.
I have a similar setup, ASUS P5Q3 and I want to get xeon from ali and 8 or 16 gigs of memory. But the...Leave a comment:

ASUS K53SV not turning on
Pardon, but how much voltage should I be getting on AC_BAT_SYS? Is it 5 volts or is it 19 volts? Either way, it's not coming there. lul

Re: ASUS K53SV HannStar E89382 no 3.3V I need schematics
To open FZ? I have FlexBV..
I need proper schematic for K53SV...
Look at PQ8802 for example...

ASUS K53SV HannStar E89382 no 3.3V I need schematics
First of all, if it says HannStar E89382 on the board does that mean that the board is HannStar or it could be Compal?
Because I've gotten two different so called schematics off the internet and none of them has same components as in the boardview.
FlexBV fials to work and my brain fails to work in manual search mode, nothing found on boardview can be found in schematics.
Which schematic do I use?
Where do I look for thingy that generates 3.3V for me?... -
Re: HP Elitebook 2740p - starts on battery only
This might seem stupid. But by any stretch of imagination have you maybe enabled battery calibration discharge? It's a setting from windows that will discharge your battery completely so that it can be recalibrated.
I know this sounds silly.
But let it die on battery.Leave a comment:

Re: Dell Latititude ic equivalnt
TPS51285B was replaced with RT6575A
on Compal-La-9591P

Interesting that doing a search on aliexpress for TPS51285B gave me a boat load of results ranging fro $2 to $5 bucks for 5 pieces from china with free shipping.
Doing same search on amazon resulted in 10 pieces lots for about $10 to $20 on average.
I bet you can also find them on chip dip and other sites if you search properly.Re: Dell Latititude ic equivalnt

Re: Killed a custom HP WLAN chipset - now how to fix it!
Although, I take it back, you might have no flipped but reversed the cable. In which case you need to make sure while the cable is unplugged that you have 3.3V on the motherboard side. Then you check the fuse on the card if it has one.
If you getting 3.3V and no fuse issues, then you just need to order new card, link provided in previous post.Leave a comment:

Does it it actually boot? If yes, boot into memtest86 latest version and test memory.
Going to BIOS and loading safe defaults or something similar might solve the issue.Re: Dell 1720 caps key blinking<br /...lve the issue.Re: Dell 1720Leave a comment:

Re: Killed a custom HP WLAN chipset - now how to fix it!
See pic. There is no way in hell you could have made contacts if you flipped cable. Then must be the problem with flex cable. You need to check every single contact, which is not hard. If it is the flex, then you can jumper with budge wire.
The card is HP Spectre 13-V Intel 8260D2W AC WIFI 867Mbps Bluetooth 4.2 W/ Cable LS-D401P
It is basically a dauther card with this [URL="https://www.aliexpress.com/i/32827469668.html"]thing[/URL] installed onto it.

Re: Killed a custom HP WLAN chipset - now how to fix it!
I don't imagine it be anything more than PCIE card with custom connector, look for fuse on the other side. Sometimes they are labeled F on silk screen, othertimes they are not labeled.
Post pic of the other side on this card.
Also post pic of the other side of flex.
Does this flex have contact pads on the otherwise. If not, then the question, how could you have burned the card or board....Last edited by u666sa; 12-18-2019, 12:58 AM.Leave a comment:

Re: Samsung Scala3_15/17A BA41-01820A no LCD_VDD3V LCD not turning on
YES! LCD3_VDDEN is low, before resistor it is 3.4mV and after resistor it is 3.1mV.
YES! It's like this.

As far as MCP1_DRAMRST# I wouldn't know where to look for it as there is no board view. I'm assuming this is DRAM voltage, mobo is working, I did connect display port and there is picture on display port.
