    I don't think the extra half a volt will be risky, but Dell use the centre pin of their charger to detect that it is genune. If it doesn't detect the genuine charger it should power on but not run at full speed.

      The extra .5 volts shouldn't cause any problems. And remember that the rated amperage is the maximum the power supply can output. If the laptop only needs 4.62A its not going to "force" more amps in. You could use 19V 1000A power supply with no issues, for that reason.

          If you read 19.5 instead of 19v it's ok, most transformers read more v without load,i have here an HP adapter that is 19v but when i test with my DM i see 19.16 v,and this goes for most adapters that i have and i have many in my scrap,without load some adapters get more volts, this is normal,although some good Q adapters should have lower variation,i also have a small adapter that is 1.5v but when i probe the output i read 6v.

            It shouldn't cause a problem.

            If anything, it's slightly better because the extra half a volt will compensate for the resistance in the power cord when it is heavily loaded.

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
              by shamsudeen
              Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
              I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

              i know that in linear power supply the noise will be very low comparing to SMPS supply....

              HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
              by Bloodhoundje
              Hi everyone,

              I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

              I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

              After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

              I have desoldered the bios chip (GigaDevice...

              Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
              by sam_sam_sam
              I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

              One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
