Preparing for Disassembly: Tools and Precautions

Before you start disassembling HP G62, make sure you have everything you need. This model is known for its flimsy plastic latches, so wrong tool may cause the case to break.

Here is the minimum set you will need:

  • 🔧 Phillips screwdriver (better magnetic, size PH0 or PH1)
  • 📏 Plastic spatula or a mediator to separate the latches
  • 🧲 Tweezers (for removing small screws and cables)
  • 📷 Smartphone for photographing disassembly stages
  • 🧴 Alcohol and cotton swabs (for cleaning contacts)

Pay special attention workspace organization. Organize the screws into groups (for example, “cover”, “keyboard”, “system board”), as in G62 screws of different lengths are used. The screws under the laptop legs are shorter than the others - if you confuse them with long ones, you can damage the motherboard.

Removing the keyboard: the most difficult step

Keyboard in HP G62 is a headache for many users. It is attached not only to screws, but also to plastic latches, which are easy to break. Before you begin, make sure you have unscrewed all 3 screws under the top panel (one is hidden under the warranty sticker).

Withdrawal algorithm:

  1. Carefully pry the keyboard from the side with a plastic spatula TouchPad.
  2. Lift it 1–2 cm and find the cable going to the motherboard (connector KB_CON1).
  3. Snap the cable lock upwards (do not pull on the cable itself!).
  4. Remove the keyboard completely, placing it face down on the touchpad.

If the keyboard does not respond, check:

  • ✅ Are all the screws unscrewed (including the one under the sticker)?
  • ✅ Are there any latches left in the area? F1–F12?
  • ✅ Does the train cling to the body?
What to do if the keyboard latch is broken?

If the plastic latch breaks off, don't panic. The keyboard can be secured with double-sided tape (for example, 3M VHB) or hot glue. The main thing is not to overdo it with the amount of glue, so as not to damage the cable. As a last resort, the keyboard can be replaced with a new one (part number for HP G62 — 6050A2469901 or 6050A2469902 depending on the layout).

After removing the keyboard you will have access to:

  • 🔌 Touchpad cable (connector TP_CON1)
  • 🖥️ Motherboard mounting screws (6 pieces)
  • 🔊 Speakers (secured with double-sided tape)
💡

Before disconnecting the touchpad cable, take a photo of its location. B HP G62 the connector is often confused with KB_CON1, which results in the touchpad not working after assembly.

Replacing thermal paste and cleaning the cooling system

One of the most common reasons for disassembly HP G62 — overheating. Due to dried thermal paste and dust in the heatsink, the laptop starts to slow down or suddenly turns off. To replace thermal paste you will need:

  • 🧴 Thermal paste (we recommend Arctic MX-4 or Noctua NT-H1)
  • 🧹 Brush for cleaning the radiator
  • 💨 Can of compressed air (optional, but convenient)

Procedure:

  1. Disconnect the cooler cable (connector FAN1).
  2. Remove the 4 radiator mounting screws diagonallyso as not to deform the board.
  3. Remove the heatsink and clean it of old thermal paste with alcohol.
  4. Apply a thin layer (about the size of a pea) of new thermal paste to the CPU And GPU (if you have a discrete video card).
  5. Blow dust off the radiator and reassemble everything in reverse order.
⚠️ Attention: B HP G62 a common problem with peeling of video card chips (especially for models with ATI Radeon HD 5470). If after replacing the thermal paste artifacts remain on the screen, the laptop needs GPU resoldering.
💡

After replacing the thermal paste, be sure to check the temperature in HWMonitor or AIDA64. Normal values under load: CPU — up to 85°C, GPU - up to 90°C. If the temperature is higher, reapply the paste or check the cooler.

Replacing RAM and hard drive

Upgrade HP Pavilion G62 usually comes down to replacement RAM And HDD to SSD. Model supports up to 8 GB DDR3 (2 slots) and any 2.5" SATA drives.

Replacing RAM:

  1. Open the black cover on the back panel (secured with 2 latches).
  2. Unclip the latches on the sides of the memory modules.
  3. Insert the new planks at an angle of 45° and secure them.

Replacing a hard drive with an SSD:

  • Unscrew the 4 mounting screws HDD.
  • Remove the hard drive along with the carrier.
  • Move the skid to SSD (the screws usually match).
  • Connect SSD to the connector SATA and secure with screws.

After replacement HDD to SSD recommended:

  • 🔄 Reinstall Windows (for optimal operation with the new drive).
